d) Describe any four features of the earth's crust.
Answers
Answer:
From mud and clay to diamonds and coal, Earth's crust is composed 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
While continental crust is thick and light-colored, oceanic crust is thin and very dark. Oceanic crust is only about 3-5 miles thick, but continental crust is around 25 miles thick. 25 miles may sound very thick, but the crust is actually the thinnest of Earth's three layers, making up only 1% of Earth's volume.
In geology, the crust is the outermost solid shell of a rocky planet, dwarf planet, or natural satellite. It is usually distinguished from the underlying mantle by its chemical makeup; however, in the case of icy satellites, it may be distinguished based on its phase.
The crust is deepest in mountainous areas. It can be up to 70km thick here. The continental and oceanic crusts are bonded to the mantle, which we spoke about earlier, and this forms a layer called the lithosphere. This layer is cool and rock solid.
Explanation:
hope it helps you....
The crust of earth is a thin, light and made up of oxygen, aluminum and silicon sheets.
Explanation:
- Earth's crust is the outermost layer and is made of lighter elements and
- It has less density as compared to the oceanic crust.
- It's made of igneous, sedimentary, and metamorphic rocks and occupied less than one percent of earth's volume.
- It's typically 30 km thick and is also called the lithosphere.
- It is mainly made of silicon, aluminum, iron, calcium, magnesium, potassium, and sodium oxides.
