This is described as a subduction zone.
That would be Subduction.
As new oceanic crust is being made in one area older crust is being subducted, (pushed or pulled down), in another area, so Earth stays about the same size.
the earth's crust is 2100 ki. down the earth.
Do you mean under the Earth's crust or above it? If you mean under it: The heat under the Earth's crust rises and falls as it heats and cools. Above the crust, the sun heats the earth, heat rises, cools, falls back down. Hope that helps.
How do THEY get back to earth?!
The mid ocean ridge is the area of the ocean floor that is associated with the breaking down of the oceanic crust. This area is known for seafloor spreading.
The mantle is located between the earths core and crust. The mantle is estimated to be about 1,800 miles or 2,896.8 kilometers down from the earths crust.
A volcano happens when there is rupture in the crust of the Earth where it reaches down into the mantle.
the earth was a big hot ball made up of many rocks and gases. After millions of years the outer portion of the earth coooled down. We live on this outer layer of the earth called the Crust.
Well, All I can said is. When earth is crated its full with magma and lava. That pretty much when earth don't have any crust. But, when the earth cools down, it turn to hard rock, and some of the lava and magma are inside the earth's core
The coolest layer is the crust. The crust is on the surface of the earth (where we are). The further you go down the hotter it gets, the inner core that is at the center of the earth is as hot as the surface of the sun!
Only the crust. The temperature and pressure increases as you go further down into the earth.
Go outside onto the grassy ground. Then look down. There you go, the earths Crust front row seats. The earths crust is the farthest outer layer of the earth.
new crust forms at divergint bounderies where plates move apart magma oozes up and cools down and creates new crust and the old crust moves away and sucks in the earth
the outher part of the earth consitin of the crust and upper the mantle appoximentaly 100km(62mi.)think.
Convection currents inside the Earth happens. The part where the convection currents go up, it brings up materials from the mantle like rocks. This forms new crust. When the convection currents go down, it brings down some older, colder oceanic crust to the mantle, destroying it. In conclusion, the crust is formed and destroyed when convection currents inside the Earth happen.
The crust is the cool part of the Earth. It is the surface we live on. It should be at a comfortable temperature until it reaches down to the mantle, the next layer. That area will be hotter. Then at the center, is the core. That is the hot part of the Earth's interior. It is about 3500° C. Estimates vary from 2000 to 7000, but it is HOT!
The area is called a Subduction Zone.
