Detailed explanation-1: -Oceanic Crust is the thinnest layer of earth.

Detailed explanation-2: -The Earth’s crust is the outer layer of the Earth and is about 5 to 25 miles thick depending on its location. It is the thinnest layer, only about 3-5 miles thick under the oceans which is called the oceanic crust. Under the continents it is about 25 miles thick, which is called the continental crust.

Detailed explanation-3: -The crust is what you and I live on and is by far the thinnest of the layers of earth. The thickness varies depending on where you are on earth, with oceanic crust being 5-10 km and continental mountain ranges being up to 30-45 km thick.

Detailed explanation-4: -“Crust” describes the outermost shell of a terrestrial planet. Our planet’s thin, 40-kilometer (25-mile) deep crust-just 1% of Earth’s mass-contains all known life in the universe. Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals.

Detailed explanation-5: -Crust. Earth’s crust is what we walk on every day. It is the thin (relatively) outermost layer that wraps around the Earth and ranges in temperature from 500 to 1, 000°C. The crust is split into two types, continental and oceanic.
