The amount of crust on Earth remains relatively constant because crust is neither created nor destroyed in significant amounts. Earth's crust is continually recycled through processes like subduction and seabed spreading, leading to a balanced crustal mass over time.

How is crust similar to lithosphere?

The Earth's Crust, Lithosphere and Asthenosphere. Crust, the upper layer of the Earth, is not always the same. ... The tectonic plates are made up of Earth's crust and the upper part of the mantle layer underneath. Together the crust and upper mantle are called the lithosphere and they extend about 80 km deep.


Why does new crust form but the earth doesn't get larger?

New crust is constantly being formed at mid-ocean ridges through volcanic activity. However, the Earth does not get larger because as new crust is formed, older crust is subducted back into the mantle at subduction zones, maintaining a relatively constant amount of crust on the Earth's surface.


Your moon always shows the same face to the earth?

The moon always shows the same face to the Earth due to its synchronous rotation, meaning it takes the same amount of time to rotate on its axis as it does to orbit the Earth. This synchronization occurs because of the gravitational forces between the Earth and the moon.


How much does water grow on the earth each year?

The amount of water on earth does not change. Some of it may become ice, or melt into water, but the global amount is always the same.


How do ocean trenches help explain why crust added at ocean ridges doesn't make earth any larger?

Ocean trenches were discovered as a sign of destructive plate margins. These plate margins cause oceanic crust to subduct below the continental crust at the oceanic-continental boundary, and force the oceanic crust to move down into the Earth's mantle and melt into basaltic magma. As this is happening, magma at oceanic ridges is creating new oceanic crust at the mid-oceanic ridges. Overall, these two processes cancel each other out and so the total amount of oceanic crust is staying aproximately the same. Therefore the Earth is not growing. Hope this helps :)

Why does the earths crust stay the same size?

The amount of crust present on Earth always stays the same. The amount of crust descending into the mantle is balanced by the amount of crust formed at mid-ocean ridges.

Is the amount of water in earth's atmosphere and on earth always the same?

Yes - the Earth has a finite amount of water on it. This water cycles between the oceans and the atmosphere.


Since new crust is constantly being added why does earth's surface not keep expanding?

Crust is made from recycling old crust so that there is still the same amount. The earth doesn't expand because there is a cycle that keeps the proportions the same throughout the entire cycle.

It takes the moon the same amount of time to orbit Earth once as it does to rotate on its axis?

Yes it does. This means we always see the same side of the moon facing Earth.

Which is thicker earths crust or lithosphere?

the lithosphere and the crust of the earth are the same lithosphere is another word for crust so the thickest is both of them.


How is crust and lithosphere the same?

The crust is the outermost layer of the Earth's surface, while the lithosphere includes the crust as well as the uppermost part of the mantle. In this context, the crust is part of the lithosphere. The lithosphere is composed of the crust and the rigid upper portion of the mantle and is divided into several tectonic plates.
