Which is the outermost part of the earth?

Correct option is C

Sol. The outermost layer of the earth is called crust. It is also known as earth's crust.

•  Earth's crust constitutes less than 1% of the earth's volume.
• Earth's crust is made up of soil, rocks and different types of minerals and mostly covered with water.
• The crust, mantle, and core are the three main layers of the Earth.

These three layers each have multiple layers as well.

•  Crust: the main crust and the lithosphere (bottom of crust shared with upper mantle). the outer layer of rock on which humans and animals live and plants grow.
• Mantle: lithosphere (shared with crust), asthenosphere, central mantle (transition zone) and lower mantle. a semi-solid magma layer consisting of iron, magnesium, and silicon.
• Core: inner core (solid) and outer core (liquid). centrally located solid mass of metal (inner core) and a liquid mass of iron and nickel (outer core).
