Earth's Layers and Properties

The video tutorial explains how to use page 10 of the reference tables to understand the inferred properties of Earth's interior. It covers the lithosphere, Moho, asthenosphere, and the density, pressure, and temperature of Earth's layers. The video also discusses the melting points and depth of these layers, providing a comprehensive guide to interpreting the reference tables.

What two components make up the lithosphere?

• Asthenosphere and core

• Mantle and core

• Crust and rigid mantle

• Crust and asthenosphere

What is the consistency of the asthenosphere often compared to?

• Water

• Sand

• Peanut butter

• Rock

What is the density of the continental crust at the Earth's surface?

• 3.0 grams per cm³

• 2.7 grams per cm³

• 9.9 grams per cm³

• 5.6 grams per cm³

Which layer of the Earth has a density range of 9.9 to 12.12 grams per cm³?

• Crust

• Asthenosphere

• Inner core

• Outer core

At the bottom of the stiffer mantle, what is the approximate pressure?

• 7 million atmospheres

• 1.5 million atmospheres

• 3 million atmospheres

• 5 million atmospheres

What is the temperature at the bottom of the stiffer mantle?

• 7000 degrees Celsius

• 5000 degrees Celsius

When does a section of the Earth's interior become liquid?

• When the temperature is above the melting point

• When the temperature is below the melting point
