Reading Comprehension - Layers of Earth

Earth's Layers 

Scientists who study the earth's layers are called geologists.  Since they cannot see the inside of the earth they use geographical clues to help them.  These clues are gathered from activities such as volcanoes and earthquakes.  From these clues geologists hypothesize (make an educated guess) what they think the earth actually looks like.
Geologists believe the earth is neither liquid nor solid all the way through.  It is a made up of different layers.  Some of these layers are solid.  Some are liquid, and some are both.  The layers of the earth have special names.  They are the crust, the mantle, and the core.  These layers vary in width and temperature.  Look at the picture below.
Earth Layers
The thin crust, or outer layer of the earth is made mostly of rock.  The thickness of this layer varies from 3 to 34 miles.  Below the crust is the mantle.  The mantle is about 1,800 miles thick and made mostly of solid rock.  It is the thickest layer of the Earth. The mantle is also very hot - about 5,400 degrees F in some spots.  The center of the earth is called the core.  It is about 2,200 miles thick.  The core is extremely hot - about 7,200 degrees F.  The core is further divided into an inner core and an outer core.  The outer core is a liquid layer of melted nickel and iron.  The inner core is made of solid nickel and iron.
