crust

Earthquakes leave scars in the Earth's crust.

It's still here, imprisoned in the earth's crust.

And in this case, we especially want to know if any of the mantle, the layer beneath the crust, was exposed by the impact.

Earth’s crust contains very little of this element, but most asteroids contain a lot more.

All are slowly moving because the plates float on a denser sem-iliquid mantle, the layer between the crust and Earth’s core.

Earth’s surface is not made up of a single sheet of rock that forms a crust but rather a number of “tectonic plates” that fit closely, like the pieces of a gain jigsaw puzzle.

If Earth became as hot as Venus, much of its carbon dioxide would be boiled out of the oceans and baked out of the crust.

Ganymede is close enough to Jupiter that tidal forces from the giant planet may have episodically heated its interior and triggered major convulsions on its crust.

Extensive mountain ranges were formed from compression of the crust, forming long ridges with parallel valleys spaced one to two kilometers apart.

Some features formed when the crust cracked, flooding many of the craters with water from the interior.

Measurements of its gravity field tell us that the rock and metal sank to form a core about the size of our Moon, with a mantle and crust of ice floating above it.

The drill holes passed through more than a thousand meters of coral before reaching the rock substratum of the ocean floor, and indicated that the coral had been growing upward for tens of millions of years as Earth's crust subsided at a rate of between 15 and 51 meters per million years.

But one well-regarded theory is the crack hypothesis, which assumes that hot spots are created when a piece of the crust gets stretched thinner and thinner and the resulting stress causes small cracks to open up at weak spots in the crust,

because so far, no one's been able to actually observe what's happening that far beneath the Earth's crust.

These plumes well up from deep inside the planet's interior, maybe even as deep as its core, and rise all the way up to melt through the Earth's crust.

molten rock or lava, flowing up through the earth's crust, which means, of course, that volcanic activity there can't be explained simply by plate tectonics.

Professor:Okay. We know the Earth's surface, the crust, is made up of tectonic plates, and these huge slabs of rocky crust are slowly sliding over or under or past each other,

Tectonic movements involve displacements in the plates that make up Earth’s crust.

So that's how we get a mascon, a spot in the crust with newer crust material that's more dense than the material all around it.

Anyway, the material flowing up from below the crust is more dense than the crust itself.

When an asteroid hits Earth, when it slams into Earth's crust, we think that causes molten rock from deep below the surface to rise up into the impact area.

But when we talked about how would actually exists inside earth’s crust, most people think that there are huge, pools of oil sitting around in caverns somewhere under there.

And like coal and natural gas, it’s found in the rocks of Earth’s crusts.

The snow had a fine crust on it.

As the water evaporates, a crust of salt is left on the surface of the soil.

You know planetary researchers love studying deep craters to learn about the impacts that created them, how they redistributed pieces of the planet's crust.

Individual specimens of Allende are covered with a black, glassy crust that formed when their exteriors melted as they were slowed by Earth's atmosphere.

but rather from just beneath the surface crust.

Do you want the crust?

So what do you do for a crust?
