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.
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. The mantle is 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.
What else can I help you with?
Is it hot or cold when we go deep inside the earth?
Hot.
What is rare earth metals?
Those metals which are kept deep inside the earth. They are alkaline in nature.
What is the complete predicate in volcanoes are places on the earths surface where molten rock gases and ash from deep inside the earth are ejected?
"are places on the earth's surface where molten rock, gases, and ash from deep inside the earth are ejected."
What is a thick gooey molten material inside a volcano or deep inside earth?
Magma is inside the volcano, and it becomes lava when it comes out. :)
The molten material deep inside earth from which igneous rocks is called what?
magma
When magma cools deep inside earth?
When magma cools deep inside earth, igneous rockforms.
Where is the core in earth?
deep inside the earth
Are there diamonds inside the earth?
Diamonds are formed deep within the earth's mantle.
What is thick gooey molten material inside a volcano or deep inside the earth?

Where are diamonds made?
Deep inside the earth, where there is intense heat and pressure.
Why does magma from deep inside Earth rise toward the surface?
cuz
What Comes from deep inside the earth and does NOT depend on the sun?
natural gas
Why are coal mines deep inside the earth?
Coal mines are usually deep inside the earth because coal deposits form over millions of years in layers of sediment. These layers are then buried deep underground by geological processes, making it necessary to dig deep to access the coal. Additionally, mining deeper coal seams can result in higher yields and better quality coal.
Which type of rock forms deepest inside Earth?
The type of rock that forms deepest inside Earth is known as igneous rock. This type of rock is created from the solidification of magma deep within the Earth's crust or mantle. Examples of igneous rocks that form deep inside the Earth include granite and basalt.
