Earth's+Interior+Assignment

Look at the powerpoint presentation on the Earth’s Interior and answer the following questions in your science notebook. Make sure you put the title, Earth’s Interior, at the top of the page: How many layers are there inside the Earth? Describe the crust. How hot and how thick is the mantle? Describe the outer core. Describe the inner core.

How do we know all of this if we've never been down there?

Why is the Earth's spinning core so important to us?
