GEOLOGY

Detailed explanation-1: -“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-2: -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.

Detailed explanation-3: -Outermost layer of earth is called Crust. Other layers are mantel, outer and inner core. Ans: Crust.

Detailed explanation-4: -Earth’s crust is Earth’s thick outer shell of rock, referring to less than 1% of Earth’s radius and volume. It is the top component of the lithosphere, a division of Earth’s layers that includes the crust and the upper part of the mantle.
