The magma rises to the crust above it mostly because of the cracks that appear in the crust and the high pressure from the mantle that pushes the magma through these cracks. The cracks in the crust appear because of the tectonic activities, on and in close proximity to the plate boundaries. This is why the volcanic activities, a product of rising magma, are found along the plate boundaries. The magma can rich the crust and solidify in it, or it can come out on the surface in the form of lava flows. The one that solidifies inside the crust forms the intrusive igneous rocks, while the one that comes on the surface forms the extrusive igneous rocks. The rocks formed from the magma are the basis for the formation of the other rock types, as well as for the formation of land masses, and soils.
What conditions are needed for a hurricane to form?
Answer:
Air from surrounding areas with higher air pressure pushes in to the low pressure area. Then that "new" air becomes warm and moist and rises, too. As the warm air continues to rise, the surrounding air swirls in to take its place. As the warmed, moist air rises and cools off, the water in the air forms clouds. The whole system of clouds and wind spins and grows, fed by the ocean's heat and water evaporating from the surface.

A hurricane needs warm ocean water above 80 °F, rapid air ascent, condensation, cyclonic motion influenced by the Coriolis force, and a progression from a tropical depression to a named storm, and finally to a hurricane upon reaching wind speeds of 74 mph. These conditions are more prevalent in the tropics, leading to hurricanes that are extremely dangerous because of their devastating wind speeds and heavy rainfall.
Explanation:The conditions needed for a hurricane to form include warm ocean water with temperatures above 80 °F, which is crucial for the formation of these intense storm systems. This warm water leads to rapidly rising humid air. As the air rises, it cools, condenses, and can result in heavy rains. A critical feature of hurricanes is their cyclonic motion, influenced by the rotation of the earth, leading to a counterclockwise rotation of storms in the Northern Hemisphere and a clockwise rotation in the Southern Hemisphere due to the Coriolis force. Hurricanes start as tropical depressions, progress to being named tropical storms, and upon reaching wind speeds of 74 mph, are classified as hurricanes.
Hurricanes are most prevalent in the tropics because of the available warm water and favorable atmospheric conditions. These storms can be incredibly dangerous due to their potential to cause torrential rainfall, high winds (exceeding 100 mph), and significant property damage. The destructiveness of hurricanes is further exacerbated by the cubic relationship between wind velocity and destructive power, explaining why a hurricane's wind force can lead to massive destruction.
What are the four ways tectonic plates intersect with one another
Answer:
- Convergent plate boundary
- Divergent plate boundary
- Transform fault plate boundary
- Plate boundary zone
Explanation:
The convergent plate boundaries are the places where the tectonic plates collide. One of them subducts below the other, and gradually gets melted into the astenosphere. They cause formation of mountain ranges as they lift up the surrounding area.
The divergent plate boundaries are the places where the plates are moving away from one another. At these boundaries we have the formation of new crust, with its trade mark feature being the mid-ocean ridge.
The transform plate boundaries are the places where the plates are moving past each other, with both of them moving in opposite direction and sliding against one another. They create lot of stress to the surrounding area, often resulting in the formation of faults parallel to the boundary.
The plate boundary zones are the places where the boundary is very complicated and can not be put into a single category. At these places there's numerous micro plates that have different interactions with the large plates as well as between each other.
What kind of information do the seismic stations collect
Answer:
About earthquakes
Explanation:
A seismic station collect data related to the earthquakes.
There are many, even hundreds depending on the location, earthquakes every day. Most of them are of very low intensity and are not felt by the humans. Many animals can detect smaller tremors than we do.
Collecting this data is important to be able to model and try to predict bigger earthquakes, that also has a consequence on the building code of some regions.
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.
Where is the temperature of the mantle material greater?
Answer:
At the boundary with the core.
Explanation:
The mantle is the second layer from the top. It is bordered by the lithosphere above it, or rather by the crust, and by the outer core below it. The mantle is a layer which is in viscous state, being mostly consisted of molten metals and rocks. The temperature of this layer is not the same all throughout it, but it varies a lot. The temperature at its top part is around 200 C degrees, while the temperature at its bottom is around 4,000 C degrees. There's two reasons for this. One is that the core is very hot, so it makes the bottom part of the mantle very hot as well, and the other one is that the lithosphere is much cooler, as well as constantly getting new, cold, crust in it, which makes its top part much cooler. The mantle is the layer responsible for the movement of the tectonic plates on the surface, as it is the layer where the convection currents occur and drive the plates' movement.

Slowness in terms of gross domestic production and decline in various sectors of the economy.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.
Where was the first wildlife refuge formed in 1903?
Answer:
Pelican Island, Florida
Explanation:
The first wildlife refuge was created in 1903 by President Theodore Roosevelt.
It was created to protect egrets and other birds of the area from extinction due to the practice of plume hunting, which consists in hunting birds not their meat but only for their feathers. Some bids feathers, like the egret, were particularly appreciated for their beauty and used in hats and other pieces of clothing.
Which of the following is an essential characteristic of an index fossil?
the fossil organism lived only in a specific type of environment
the fossil organism lived for only a short span of geologic time
the fossil organism was exceptionally well preserved
the fossil organism didn't occur over a wide geographic area
Answer:
the fossil organisms lived for only a short span of geologic time
Explanation:
The index fossils are very useful when it comes to determining the relative age of the rock layers, as well as the other fossils found in the same layer with them. These fossils have four basic characteristics, they appear only in limited geologic time, they are widespread, abundant, and distinctive. The fact that they are limited in their geologic existence is very good for the geologists as when they find a fossil like this they are immediately aware of the geologic period they are working with without having to make examinations. Also, these fossils can be found in abundance and in numerous places around the world, thus the same fossil can be used as a time scale almost everywhere. Being distinctive also helps a lot because the geologist can immediately be aware of the type of organism without having to further examine it.
Answer:
The organism only lived for a short period of geologic time

"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?
Answer:
yes
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.What mountain range is nicknamed the blue ridge mountains?

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 happens at plate boundaries between oceanic and continental plates?
Answer:
Subduction
Explanation:
When an oceanic tectonic plate and continental tectonic plate move toward each other and collide, they create subduction zone. The subduction zone is basically the boundary between the plates, where the oceanic plate slowly moves below the continental plate, gets into the mantle and is melted in it, thus destroyed. The oceanic plates are denser and heavier, but also lower and their crust is not as deep, while the continental plates are less dense and lighter, but higher and have much deeper crust. This results in the oceanic plate to move below the continental plate above it. The subduction zones create a lot of geological activity, and the earthquakes and volcanic activities are something that happens regularly. The volcanic island chains are mostly formed in close proximity to this type of boundaries, which we can easily see with the Pacific Ring of Fire.
At boundaries between oceanic and continental plates, either volcanic mountains form due to subduction of the oceanic plate under the continental plate, or deep trenches form in ocean floors when one oceanic plate subducts under another.
Explanation:In the field of Geography, the boundaries between oceanic and continental plates are known as convergent boundaries. At these boundaries, two things could happen: Volcanic mountains forming due to subduction of the denser oceanic plate beneath less dense continental plate, or the formation of trenches in ocean floors. For instance, the Andes Mountain range in South America formed from the subduction of the Nazca Plate under the South American Plate.
In contrast, trenches like the Mariana Trench in the Pacific Ocean form when oceanic plates collide, with one being forced under the other, leading to the formation of a deep underwater canyon.

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.
