Answer:
B. Isostatic equilibrium
Explanation:
Isostasy is a state of balance or equilibrium between the lithospheric plate and the underlying mantle, the asthenosphere.
Due to the weight of the lithosphere, part of it sinks into the plastic asthenosphere and settles to an equilibrium position. This is what causes changes and differences in elevation on the earth.
As with all natural processes, the earth in itself tries to achieve stability and equilibrium in all it parts. The crust and a portion of the mantle forms the brittle lithosphere. The lithosphere floats on the plastic mantle. Due to density contrast, portions of the lithosphere tends to sink into the mantle from time to time. The lithosphere reaches a point where it no longer sinks and establishes an equilibrium with the asthenosphere.
This isostatic adjustment that occurs within the earth is responsible for the changes in elevations from places to places.
When portions of the crust gets eroded, it becomes lighter and rises up. When materials are deposited in adjacent areas or glaciers forms, they add increasing weight to the crust and causes it to further settle within the asthenosphere.
Answer:The two competing ideas in _______ were formulated by the English mathematicians John Pratt and George Airy.
Due to the thick and viscous material in the asthenosphere, the liquid is called _______.
_______ is reached when areas of the lithosphere stop rising.
A change in density occurs as a result of _______ compression.

What are some different phases of climate the earth has gone through?
Answer:
- Warm and wet
- Glaciation
- Inter-glacial
Explanation:
The climate on Earth has constantly been changing and still continues to do so in the present. There has been different climate phases. Some periods of the geological past have been very warm and wet. The climate has been tropical wet, with high temperatures and high amounts of precipitation. There have been periods that have been much colder, with ice caps expanding much further than the poles, and apart from the lower temperatures, the climate has also been much drier. And there are the inter-glacial phases. In this phases the climate seems to be more diverse, arranged roughly by latitude, it is more moderate in general when compared with the other two extremes.
The flattened circular part of the galaxy is called the galactic _________.
The flattened circular part of the galaxy is called the galactic disk.
Flattened circular part of galaxy is called galactic disc.
Explanation:Galactic disk is disk galaxies which consist of gaseous components and stars dust and other material moving in a circular motion about a common axis. Some disk depicts a spiral pattern which is a result of the rotational movement while some have featureless form.
The disks are thin since their motion depends on the disc's plane. The thickness of the disc varies with different galaxies. For example, the Milky Way disc is 1 kpc thick. Galactic disc studies have been understood or advanced by studying motions, ages of stars, and etc.
What type of crust is found under the continents?
Answer:
continental crust. I hope this helped
Continental crust is made up of many different types of rocks, with the average composition being granite. It is thick and has a relatively low density, allowing it to rise higher on the mantle compared to the denser oceanic crust. The basins formed by the oceanic crust sinking into the mantle are filled with water, creating the Earth's oceans.
Explanation:Continental crust is made up of many different types of igneous, metamorphic, and sedimentary rocks. The average composition is granite, which is much less dense than the mafic rocks of the oceanic crust. Because it is thick and has relatively low density, continental crust rises higher on the mantle than oceanic crust, which sinks into the mantle to form basins. When filled with water, these basins form the planet's oceans.
What is the name of the peninsula that separates africa from asia
Sinai is a triangle shaped peninsula, located in the Asian continent and politically belongs to Egypt (this is why this country is considered a transcontinental land).
It is important to know that the border between Africa and Asia is not clearly defined. However, the Sinai Peninsula is often considered to be this border.
Although this peninsula divides the African continent from the Asian continent, many authors consider that the true boundary between both continents is the isthmus of Suez.

Suppose you measure the parallax angle for a particular star to be 0.1 arcsecond. The distance to this star is
Parallax is the angle formed by the observation lines to a very distant object from two separated points.
The procedure to measure this distance in the case of a star, is based on observing it from two different places far away from each other, and then through trigonometry reach to the following relationship:
[tex]d=\frac{r}{sin(p)}[/tex] (1)
Where:
[tex]d[/tex] is the distance from Earth to the observed star (in Parsecs [tex]1pc=206265AU[/tex])
[tex]r[/tex] is the earth-sun distance that is equivalent to an astronomical unit (1AU=150000000km)
[tex]p[/tex] is the angle of the parallax (in arc seconds [tex] '' [/tex])
Now, the distance to an object (measured in parsecs) is the reciprocal of the parallax (measured in arcseconds).
Then, in its simplified mode, the stellar parallax is given by the following equation:
[tex]d=\frac{1}{p}[/tex] (2)
[tex]d=\frac{1}{0.1''}[/tex]
Finally we have the distance to the star:
[tex]d=10pc[/tex]
Which country is nicknamed the emerald isle?
Emerald Isle is also known as Ireland.
Final answer:
The Republic of Ireland is known as the Emerald Isle, due to its lush green landscape. The country gained independence from Britain in 1921, and has since become an important part of the global economic community.
Explanation:
The country nicknamed the Emerald Isle is the Republic of Ireland. This nickname is attributed to its lush, green landscape, which is a result of its Type C climate, providing adequate rainfall for crops and vegetation. The whole island of Ireland was under British control for centuries until 1921 when the Republic of Ireland gained independence, excluding Northern Ireland. The conflict for independence has deeply influenced Irish culture and literature. Today, as an independent country, the Republic of Ireland is a significant player in the global economic community, despite having few natural resources other than its green countryside which significantly contributes to its tourism.

Can australia be both east and west of south america, explain.
Answer:
Yes, it can.
Explanation:
Australia can be and it is both east and west of South America in practice. A confusion usually occurs because of the imaginary lines set for the human needs and the way the maps are made, so people may think that every continent can be only on side of the other continent. The Earth is rounded though, and naturally there isn't any lines for separation of the sides. So if we take the location of South America and Australia, we can see that Australia is both east and west from South America, as South America is to Australia as well. Australia is located west of South America's west coast, across the Pacific Ocean, but if we take the other side, Australia is located on the east of the eastern coast of South America, with the Atlantic Ocean, Africa, and the Indian Ocean being between them.
Final answer:
Australia can be considered both east and west of South America depending on one's perspective of Earth as a spherical object and the direction of travel. Map projections such as the Mercator projection and upside-down world maps influence our perception of these directions. Explorers like James Cook had a significant role in the development of eastern Australia, which is home to several major cities and the Great Dividing Range that affects the local climate.
Explanation:
Whether Australia is to the east or west of South America depends on one's perspective. Geographically, it is east of South America when we look at the traditional map with North at the top. However, since these directions are relative on the spherical Earth, if one traveled west from South America, circumnavigating the globe, one would also reach Australia. The key factor influencing this understanding is the map projection used. Additionally, societal and cultural practices that prioritize North America and Europe at the top of most maps have influenced this perception.
Explorers like James Cook spurred the settlement of eastern Australia, where urban development flourished in cities like Sydney, Melbourne, and Brisbane. Thus, historical exploration has shaped our understanding of world geography. The relative view of Australia in the east or west also is a matter of perception influenced by different map projections, like the Mercator projection or upside-down world maps.
Physically, the continent of Australia features varied geography, with the arid outback dominating its interior and the Great Dividing Range influencing the climate on the eastern coast. Moreover, Australia’s considerable distance from other landmasses has contributed to a unique ecosystem and geological stability.

One disadvantage of cloning is
A-scientists can study why nerve cells don't multiply
B-allows the continuation of species facing extinction
C-scientists can study how organisms grow and reproduce
D-new organisms are often sickly and do not live long lives
Answer:
Disadvantage of cloning is new organisms are often sick and don't live long.
Explanation:
Cloning is considered to be one of the biggest scientific achievements of mankind to clone any organism or species is just like replacing it with a new one but at the cost. As this species develops disease quite easily and has a shorter life span as the scientist has discovered that the genetic constituent in the genome of the species changes as a reaction to the reproductive system a similar type of system works in binary format and creates two identical or twin species. This evolutionary process creates a distinction among the fittest and finest species which ultimately results in another end to slow down the functioning of basic body parts or premature death.Belgian settlers in south africa were known as boers- true or false
Boer is a Dutch term meaning 'peasant', this how the settlers of Dutch origin in South Africa and Namibia and their descendants were called, although they were also called Afrikaners.
This ethnic group of Dutch origin was mainly characterized by carrying out tasks of mainly agrarian character, speaking the Afrikaans language (derived from Dutch) and practicing the Calvinist Christian religion.
It should be noted that this community had its origin in the Dutch colonization of the Buena Esperanza Cape area, which began in the mid-seventeenth century and led to a slow but steady immigration in southern Africa of European settlers from the Netherlands.

The north star has very little apparent rotation in the night sky because
The North Star has very little apparent rotation in the night sky because: it lies directly above the Earth's axis of spin. The background stars during a solar eclipse are those of constellations: of the opposite season.
Hope this helps:)
Polaris, the North Star, seems to rotate minimally in the night sky because it is situated close to the north celestial pole. As Earth spins, this causes other stars to seem to move more noticeably around Polaris, which remains mostly stationary. Earth's axial precession also means that the celestial pole will shift over time, moving away from Polaris.
Explanation:The North Star, also known as Polaris, has very little apparent rotation in the night sky because it is located close to the north celestial pole. As the Earth rotates on its axis, the sky appears to pivot about the celestial poles. Polaris remains at a nearly fixed point in the sky, while other stars seem to move significantly in a circular motion around it.
It's important to understand the north circumpolar zone, which is the part of the sky that always stays above the horizon for observers in the northern hemisphere. This zone includes Polaris and some star groups like the Big Dipper, Little Dipper, and Cassiopeia. The apparent rotation of the stars in the night sky is a result of the Earth's rotation, but the North Star's position close to the Earth's rotational axis makes it seems almost motionless.
Another crucial fact is the Earth's axial precession, a slow wobble of the Earth's axis due to the gravitational pulls of the Sun and Moon. This wobble takes about 26,000 years to complete a full circle, which means that the position of the celestial poles shifts over time. Today, Polaris is closest to the north celestial pole, but in 14,000 years, Vega will hold that position.

Which one of the following can the transit method tell us about a planet?
-its mass
-its size
-the eccentricity of its orbit
The transit method allows detecting distant planets by measuring the attenuation of the brightness of a star when a planet passes between it and the Earth.
This is done based on a phenomenon in which a body (a planet in this case) passes in front of a larger one (the star), blocking (eclipsing) its vision to some extent.
So, this transit reflects the ratio of the size of the star and size of the planet. Hence, the larger the planet, more noticeable the eclipsing effect.
This is how the size of the star can be determined through its spectrum photometrically, although it does not give information about its mass.
Final answer:
The transit method can tell us about the size of a planet. When used with the Doppler method, it can also help determine the planet's mass and density.
Explanation:
The transit method primarily allows us to determine the size of an exoplanet. When a planet passes in front of its parent star as seen from Earth, it causes a periodic dimming of the star's light. By analyzing how much the light drops and for how long, astronomers can calculate the planet's size. The transit method does not directly provide information about the planet's mass or the eccentricity of its orbit. However, when combined with the Doppler method, which measures changes in the star's spectrum due to the gravitational pull of an orbiting planet, both the size and mass can be determined. This combination offers a powerful tool for characterizing exoplanets, such as helping to gauge their density and composition, as was the case with HD 209458b, the first detected transiting planet, which confirmed it as a gas giant.
The lake effect occurs when ____ air mass moves over a ____ body of water.
Answer:
-dry
-large
Explanation:
The lake effect occurs when dry air mass moves over a large body of water. When there's a dry air mass, be it warm or cold, and it moves over some large lake, thus large body of water, it changes its properties. The dry air mass picks up a lot of moisture while passing above the large body of water. As it does that, the air mass becomes wet. As it continues to move, this air mass will eventually come upon a natural barrier which will make it accumulate and go up, at certain area, the water vapor to condensate, and lot of precipitation to occur. Because this process will be happening constantly, the area will be receiving solid amount of precipitation, though the side of the water body from which the dry air mass is coming will be relatively dry.

Identify the true statement about drainage divides. A drainage divide is a ridge that separates one watershed from another. Precipitation that falls on the west side of the continental divide flows to the Gulf of Mexico and the Atlantic Ocean. The divide that runs along the crest of the Appalachians separates the Atlantic Ocean drainage from the Arctic Ocean drainage. The ultimate base level for streams on the east side of the continental divide is the Pacific Ocean.
Answer:
A drainage divide is a ridge that separates one watershed from another
Explanation:
A drainage divide is the natural feature that is dividing the watersheds, or rather it is a ridge of a mountain or hill that is dividing the waters. The drainage divides determine where the water will go, on which side, in which streams and rivers. Some of them are larger, some are smaller, but they all do the same job. Where the waters from a certain watershed will end up though depends on the topography of the terrain, which can make them the waters move in any direction, or better said from higher to lower places. This occasionally gives weird paths of the waters from some watershed, as the watershed can be very close to a big body of water, but the topography moves it away from it, and it ends up in a body of water hundreds or even thousands km away.
A drainage divide is a ridge that separates one watershed from another, determining where precipitation will drain. The other statements in the question about watersheds and drainage divides are inaccurate.
Explanation:The true statement about drainage divides is that a drainage divide is a ridge that separates one watershed from another. A drainage divide, or watershed divide, is a geographical boundary that determines into which body of water precipitation will drain. The segregation happens because the water will flow towards the lower point of elevation.
Regarding the other statements, the one about precipitation falling on the west side of the continental divide flowing to the Gulf of Mexico and the Atlantic Ocean is not accurate. Precipitation that falls on the west side of the continental divide flows towards the Pacific Ocean. Similarly, the ultimate base level for streams on the east side of the continental divide is the Atlantic Ocean, not the Pacific Ocean.
Finally, the divide that runs along the crest of the Appalachians does not separate the Atlantic Ocean drainage from the Arctic Ocean drainage. Instead, it separates watersheds that drain into the Atlantic Ocean and the Gulf of Mexico.
