The continental crust is thicker than oceanic crust, averaging about 35 kilometers in thickness, and is composed mainly of light silicates like granite, making it less dense and causing it to rise higher above the mantle. It is also thicker below mountains due to deep roots extending into the mantle.
The continental crust is significantly thicker than the oceanic crust. It has an average thickness of about 35 kilometers, although this varies considerably. The composition of the continental crust predominantly includes igneous, metamorphic, and sedimentary rocks, with granite being the most common.
Granite consists largely of silicates made of silicon and oxygen, making it less dense compared to the mafic rocks like basalt found in the oceanic crust.
Furthermore, due to the lower density and greater thickness, the continental crust rises higher above the mantle than the oceanic crust. It is also thicker below mountains than below valleys because mountains are supported by deep roots that extend into the mantle, known as isostasy.
The fauna and flora of australia are very different from those of the rest of the world. Why might this be true?
The unique fauna and flora of Australia can be attributed to several factors, including the continent's long isolation, different biogeographic realms, and human activities. Australia's isolation has allowed for the development of distinct species, while the introduction of new species and the impact of human activities have further shaped the biodiversity of the country.
Explanation:The unique fauna and flora of Australia can be attributed to several factors. One reason is the continent's long isolation from the rest of the world. Australia has been geographically separated from other land masses for millions of years, allowing for the development of distinct and diverse species. Additionally, the introduction of new species by European colonizers has further contributed to the unique biodiversity of Australia.
Another factor is the different biogeographic realms that Australia falls under. The region is separated from Asia by lines such as Wallace's Line and Weber's Line, which represent divisions in species development between the two sides. This separation has led to the evolution of unique plant and animal species in Australia.
Furthermore, human activities have also impacted the biodiversity of Australia. The southwest region of the country, for example, is considered a biodiversity hotspot but has experienced significant loss of native vegetation due to agriculture and land development.
4. What does Einstein's theory of relativity explain? Please explain
A. How magnetism reverses the fields of the poles
B. How light interacts with moisture
C. How gravity interacts with planets
D. How light interacts with gravity
General Relativity is based on the equivalence principle, which expresses the following:
A gravitational force and an acceleration in the opposite direction are equivalent, both have indistinguishable effects.
In other words, for general relativity, gravitational force and acceleration in the opposite direction have the same effect.
Then, in the case of light:
In the absence of accelerations photons travel in a straight line, but if we move quickly (accelerate), we will see how the trajectory of the photon curves.
But, how is this possible is photons has no mass and cannot be affected by gravity?
Because of the equivalence principle.
As acceleration equals a gravitational force, then gravity diverts light.
This effect is more evident in distant galaxies, which can act as gravitational lenses. So, in this way the rays of light are deflected if there is a mass accumulation nearby.
Answer: Einstein's theory of relativity explain how light interacts with gravity.

Africanized honeybees are genetically engineered bees that escaped from a research lab in Brazil. The Africanized bees are more aggressive than native species and are slowly replacing native species in Brazilian rain forests. Which statement best explains competition between native species and Africanized honeybees?
Question 8 options:
The Africanized bees deplete the resources native bees need to survive.
The native species are not reproducing as fast as the Africanized bees due to parasites.
The two species occupy the same ecological niche and compete for abiotic factors only.
The Africanized bees kill the native bees.
Answer:
The Africanized bees deplete the resources native bees need to survive.
Explanation:
The two bees species occupy the same niche and hence compete for resources. Because the Africanized bees are more aggressive, they have an advantage and therefore outcompete the native bees for the same resources. Therefore, over generations more Africanized bees are able to pass their genes to the next generation than native bees.

19. Which effect is used in a turbine to convert mechanical energy into electricity? Please explain.
A. Photosynthesis
B. Electromagnetic induction
C. Nuclear fission
D. Coalification
I think it’s b
A battery converts chemical energy into electricity, and a solar cell produces electricity from the sun's energy, but if you want to produce electricity from mechanical energy, you need an induction generator. These generators can be small enough to power a crank-style flashlight or large enough to energize entire cities, but all work on the principle of electromagnetic induction, discovered by Michael Faraday, the 19th-century English physicist and inventor. Today, induction generators running on a variety of fuels supply electricity for most of the world's population.
Faraday's induction experiment is probably one of the most important in physics, and it was a relatively simple one. He coiled a length of conductive wire around a circular core and connected the wire to a meter. He found that moving a magnet through the center of the circle caused current to flow in the wire. The current stopped when he stopped moving the magnet, and it flowed in the opposite direction when he reversed the direction of the magnet. He later formulated the law of electromagnetic induction, now known as Faraday's Law, which related the strength of the current to the magnitude of the change of the magnetic field, also known as magnetic flux. The strength of the magnet, the number of coils around the core and the characteristics of the conducting wire all influence calculations for real-world generators.
Whether located inside a household utility generator, your car or a nuclear power plant, generators generally incorporate the same features. They include a rotor with a hollow core that rotates around a stator. The stator is typically a powerful magnet, while the coils that carry electricity are wound around the rotor. In some generators, the coils are wound around the stator and the rotor is magnetized. It doesn't matter. Either way, electricity will flow.

What are the four reference points needed to calculate latitude
Answer:
the center of the earth, the north and south poles, the equator and the Prime Meridian.
Explanation:
To obtain a precise latitude, map makers use 4 universal well-known points of reference that make unanimity among the science community, to ensure consensus.
Those reference points are:
1.) the center of the earth: that is used to calculate the radius of the circles and the various angles to draw the latitude lines.
2). the north and south poles: since the latitude lines have to reach them, starting from the Equator.
3.) the equator: that's latitude 0, so it's a pretty important reference point.
4.) the Prime Meridian, as a perpendicular line for the latitude "rings" and other calculations.
And the same reference points are also used to calculate the longitudes as well.
Final answer:
To calculate latitude, four reference points are used: the equator, prime meridian, North Star (Polaris) for celestial navigation in the Northern Hemisphere, and the observer's horizon. Tools to measure these have evolved from astrolabes to sextants and GPS technology.
Explanation:
The question asks about the four reference points needed to calculate latitude, which involves understanding Earth's geometrical and astronomical features. The reference points necessary to determine one's latitude on Earth include:
The equator, which serves as the starting point for measuring latitude degrees north or south.
The prime meridian, which aids in the orientation of the global coordinate system.
The location of the North Star (Polaris) in the Northern Hemisphere for celestial navigation.
The observer's horizon, as the angle of Polaris above the horizon directly corresponds to the observer's latitude.
Techniques used to measure these points have evolved from simple tools like the astrolabe to advanced instruments like the sextant and GPS technology, which calculates a position in three dimensions using at least four satellites and principles of geometry.

1990 marked its independence from south africa
Answer:
Namibia
Explanation:
Namibia is a country located in the southern part of the African continent. It was a German colony, being named West South Africa during that period of time. The country was granted independence by Germany, but that didn't lasted long as RSA saw it as one of its provinces, so it used its military superiority and invaded the country. There has been numerous incidents and conflicts during the South African invasion, and the UN had to react in order to put things under control. Under heavy international pressure, with the guidance and monitoring of the UN, RSA granted independence to Namibia, so the country located along the western coastline of Southern Africa became independent again.

Which is farther east newfoundland or puerto rico
Answer:
Newfoundland
Explanation:
Let's take a look at both locations and find their eastern-most point.
Newfoundland:
we'll take the capital (St. John's) in reference because it's pretty much the eastern-most point.
Latitude: 47.4815685
Longitude: -53.1085765
Now, let's look at Puerto Rico:
we'll take the Punta del Este, on the island Culebrita:
Latitude: 18.312056
Longitude: -65.220939
To see which is the farther East (we'll assume from continental USA), we need to look at the longitudes, which are the vertical lines on the globe.
Since Newfoundland is at -53 degrees, and Puerto Rico is at -65 degrees, Newfoundland is closer to the Longitude 0 (Greenwich), so it's the one farther East from the continental USA.
Newfoundland is farther east than Puerto Rico since its easternmost point has a lower longitude value (approximately 52.6 degrees West) compared to Puerto Rico's easternmost point (approximately 65.3 degrees West).
The question at hand is about the geographical position of Newfoundland and Puerto Rico in relation to longitude, particularly which location is farther east. Newfoundland, located in Canada, is part of the easternmost province of Newfoundland and Labrador. Its most easterly point is Cape Spear, which has a longitude of about 52.6 degrees west. On the other hand, Puerto Rico is a Caribbean island with its easternmost point, Punta Mulas, near a longitude of 65.3 degrees west. Since lower longitudinal values are farther east, Newfoundland is indeed farther east than Puerto Rico.

Mercator projection
equal-area projection
Answer:
Mercator projection
Explanation:
Using a flat paper map to represent the sphere that is our planet has always been a challenge. The Mercator projection is one of the most common representation, although we know it is more accurate around the Equator line and the precision diminishes as you get closer to the poles.
There are other types of projections, correcting some issues, but with their own flaws too. The only accurate representation of the planet is a globe, since it matches the shape of the planet.
I'm pretty sure one of the answers is Mercator projection.

what is/are responsible for creating variation in climate and weather at different latitudes?
A. different levels of sunlight
Answer:
Varying amounts of sunlight falling over different latitudes is what is responsible for the variations in weather and climate
Explanation:
The greater the latitude of a given place means that it is farther away from the equator and hence the Sun's rays reach the place at a sharper angle thus causing the rays to be spread across a greater area. And hence a place which is very far away from the equator will have less heat than a place that is nearer to the equator. The Earth's axis as we know is tilted. This tilt is responsible for the variation in the amount of sunlight a latitude receives during different seasons.
"what if a galaxy was not tilted but was positioned toward us perfectly face-on, so stars in the galaxy are neither approaching nor receding from us, from our point of view. would the tully-fisher technique work?

Explanation:
Because no matter what we are gonna be on a sphere so there is no telling.
Answer:
No, the Tully-Fisher technique wouldn't have worked in such a scenario.
Explanation:
For the Tully-Fisher technique to work, it is required that our view of the stars allows us to read their motion. If a galaxy would be in a position facing perfectly towards us, it would've been impossible to read whether the galaxy is moving towards us or away from us. In that case, the Tully-Fisher technique would fail and our distance from the galaxy would be incalculable.The disks of spiral galaxies appear blue because

Which process cause wells on land to become saline making them unusable for drinking water
Answer:
C. Ground water infiltration
Explanation:
Ground water infiltration can cause wells on land to become saline making them unusable for drinking water.
When rain falls down, it will sip into the ground. It might encounter minerals (like salt) along its path and dissolve them until it reaches a reservoir.
That reservoir could be the well itself, but it's most likely it will be another natural reservoir nearby, in which the salt and minerals concentration will raise gradually... then that second reservoir will somehow connect with the well, contaminating its water.
