Layers of the earth
Lets start
Have you ever dug a hole in your backyard, or in the playground? How deep were you able to dig? One foot? Two feet? Or perhaps you really worked hard and were able to dig a hole that was three feet deep.
As your hole became deeper, you would quickly dig through the soft Goliath, or dirt, and begin hitting your shovel against hard bedrock. In order to continue digging, you would need a jack hammer or a drill to break through.
Suppose that you had all of this equipment available to you, how deep could you dig? The deepest mines on Earth are only about 2.5 miles (4km) deep. Some geologists have used massive drilling equipment to take narrow core samples from as deep as 7 miles (11km) beneath the surface of the Earth. This seems like a very deep hole, but when compared to the overall radius of the Earth, it is just scratching the surface. The Earth is approximately 4,000 miles (6,400 kilometers) from surface to center.
The Earth’s Crust
The first layer consists of about 10 miles (16km) of rock and loose materials scientists call the crust. Underneath the continents, the crust is almost three times as thick as it is under the oceans.
here are some pictures to what some people think the inside of earth looks like.

this one i think is the best picture that i have put up
2
this one looks a lot like 1 but gives u a different angle

this one lable it so u will know which one it is
Traveling beyond the Earth’s crust, we next encounter the mantle. The mantle extends to a depth of approximately 1,800 miles (2897km), and is made of a thick, solid, rocky substance that represents about 85% of the total weight and mass of the Earth.
the earths core (outer)
Traveling still deeper within the Earth, we next would encounter the Earth’s outer core, which extends to a depth of around 3000 mile (4828km) beneath the surface. It is believed that this outer core is made up of super-heated liquid molten lava. This lava is believed to be mostly iron and nickel.
the earth's core (inner)
Finally, we would reach the Earth’s inner core. The inner core extends another 900 miles (1448km) toward the center of the Earth. It is believed that this inner core is a solid ball of mostly iron and nickel.
