The entire earth's crust occupies just 1% of the earth's volume. The Earth's crust thickness is 30 km thick. The temperature of the crust is 2oo degrees Celsius (392 Fahrenheit) to 400 degrees Celsius (752 Fahrenheit). Mantle The Mantle is the second layer of the earth, it takes up 80% of the Earth. The mantle has two sections (Lithosphere and the. Asthenosphere). The temperature of the lithosphere and asthenosphere is 300 to 500 degrees celsius. The mantles temperature 4500 degrees celsius and made of 100% magma.
Layers of the Earth-page 4 of 5. The mantle is 84% of the Earth's mass, making it the thickest layer of the earth. We said earlier that it's highly viscous, and it's temperature ranges from 500 degrees Celsius at the crust to 4,000 degrees near the outer core.That means that the coolest part of the mantle is more than five times hotter than boiling water. OUCH!e said earlier that it's highly viscous, and it's temperature ranges from 500 degrees Celsius at the crust to 4,000 degrees near the outer core. That means that the coolest part of the mantle is more than five times hotter than boiling water. OUCH!
