Question

What layers are separated by the Mohorovician discontinuity?

• A. Crust and Mantle
• B. Crust and Core
• C. Mantle and Core
• D. None of the above

Answer 1

Answer:

A. Crust and Mantle

• The crust is the outermost solid layer of the Earth, ranging in thickness from 5-70 km (3-44 miles)

• It's composed of rocks and minerals, and is broken into several large plates that float on the more fluid mantle below.

• The mantle is the thick, rocky layer beneath the Earth's crust, extending from approximately 35 km (22 miles) to 2,900 km (1,800 miles) in depth.

• It makes up about 84% of the Earth's volume.

• Mohorovician discontinuity - It separates Crust and Mantle
