Exciting Facts About Earth's Crust!
How thick is the Earth's crust?
A. 5-10 kilometers
B. 25-70 kilometers
C. 100-200 kilometers
D. 300-500 kilometers
Answer:
B. 25-70 kilometers
The Earth's crust is generally about 5-10 kilometers thick beneath the oceans and around 25-70 kilometers thick beneath the continents.
This outermost layer of the Earth is divided into several large tectonic plates that float on the semi-fluid asthenosphere below, which is responsible for the movement of these plates.
The Earth's crust is composed of a variety of rocks, including granite, basalt, and sedimentary rocks, which vary in composition and thickness depending on the location.
It's fascinating to think about the different layers that make up our planet's surface and how they contribute to the dynamic processes that shape the Earth!
