Because soon after the earth formed, when it was still hot and mostly molten, the materials separated themselves out. Most of the denser materials, like nickel and iron, sunk towards the center (being the core) and the lighter materials floated to the surface (the crust). So due to the separation the crust composition is different than the core.
The inner core of the Earth is solid iron with a few trace elements. The crust is composed of sedimentary, metamorphic, and igneous rock.
The difference between the earths mantle and the core is that the mantle is liquid metal while the core is solid. However both are very hot.
we live on the earths crust. it is the outer most layer of earth. the core is the inner most layer with temperatures from 90,000 degrees Fahrenheit.
its soft and thick
Earth's crust is the thinnest among the other earth's layers.
The crust is the least dense of the Earth's layers. Each layer is denser than the layer above it. This is very logical, since lighter layers float on top of heavier layers.
the hardest layer of the earth's surface is the crust because it is made up of rocks and other hard materials
1. The earth outermost surface is called crust. 2.The crust is about 25m. thick beneath the continents. 3.The crust is relatively light and brittle. 4.Most earthquakes occur within in the crust.
The Earth's outermost layer of hard brittle rock is called the crust. The crust is typically about 23 miles thick beneath continents, and about 6.5 miles thick beneath oceans. The crust is relatively light and brittle compared to other Earth layers. Most earthquakes occur within the crust.

The crust. We have not been able to access the other layers.
Yes because like sedimentary rocks they stacked on top of each other
The interior of Earth, similar to the other terrestrial planets, is chemically divided into layers. The mantle is a layer between the crust and the outer core.
They are both layers of the Earth comprised of rock....other than that, there are no similarities.
The crust is the least dense portion of the solid Earth because it is the thinnest layer.
the hardest layer of the earth's surface is the crust because it is made up of rocks and other hard materials
the earth's crust is a thin layer about, the crust can be more than 80km thick in some parts and less than 1 km thick in other parts. it is the ground that we live on
consist of large sections called tectonic plates, which move relative to each other.
Well it is much smaller than the actual earth. The crust is a little tiny tiny sliver compared to the other layers. It doesn't get to show the temperature or state of matter on a model (at least most).
