State any Five characteristics of ‘The Crust’ layer of the earth
Answers
Answer:
The crust is deepest in mountainous areas.
The continental and oceanic crusts are bonded to the mantle, which we spoke about earlier, and this forms a layer called the lithosphere.
Beneath the lithosphere, there is a hotter part of the mantle that is always moving.
a crust is the outermost layer of a planet.
The crust of the Earth is composed of a great variety of igneous, metamorphic, and sedimentary rocks.
The crust is underlain by the mantle.
The upper part of the mantle is composed mostly of peridotite, a rock denser than rocks common in the overlying crust.
Earth's crust is 5 to 70 km thick. Continental crust makes up the land on Earth, it is thicker (35 - 70 km), less dense and mostly made up of the rock granite. Oceanic crust makes up most of the ocean, it is thinner (5 - 7 km), denser and mostly made up of the rock basalt.
