Layers of the earth
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.
this one i think is the best picture that i have put up
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
