Drag each label to the correct location.
cluponka [151]

Answer:

The geosphere or geosphere is the internal and solid part of the Earth that is composed of three concentric layers called crust, mantle and nucleus. Without the geosphere, human beings cannot live on the planet, since there is no solid ground. In the Earth's geosphere are rocks, minerals, magma, sand and mountains.

This layer interacts with the other layers of the earth system, including the atmosphere, hydrosphere and biosphere, and is in a state of constant motion; Sedimentary, igneous and metamorphic rocks within the Earth's geosphere undergo continuous recycling.

It is said that the Earth formed about 4.6 billion years ago from the collision of meteoric debris that created the solar system. Due to the constant collisions during its formation, the initial temperature of the planet was extremely high; It was all molten matter.

But during the next phase of Earth's formation there was a cooling, and with it, the differentiation of the Earth's layers. Dense materials sank in the center, forming a core rich in iron and nickel. The lighter magma rose to the surface, forming the thickest layer of the Earth called the mantle.

Eventually, the outermost magma cooled to form the thin layer we call Earth's crust.
