There are two types of rock that can form deep within the earth: metamorphic rock and intrusive igneous rock. Metamorphic rock forms from rock that is altered under extreme heat and pressure. Intrusive igneous rock forms from molten rock that cools and solidifies underground. This is opposed to extrusive igneous rock, which forms at the surface after being erupted from a volcano.
The kinds of rocks that formed deep within the earth are called igneous rocks. These rocks are one of the main types of rocks found in Earth.
some rocks form in the deep earth like metamorfic rocks but igneous and sedimentary rocks form on or near the earths surface
Deep in the earth is a molten iron/nickel core. No rocks survive down there, the minerals in rock are too light (they float on the heavy iron and nickel core).

Metamorphic
They can learn about conditions deep inside Earth, where these rocks formed. In addition, forces inside Earth sometimes blast rock to the surface from depths of more than 100 kilometers. These rocks provide clues about the interior.
The formation of intrusive igneous and metamorphic rocks.
Metamorphic rocks form when existing rocks are exposed to heat and pressure deep within the Earth's surface

forms from dead plants and animals that compress deep in the Earth's crust over millions of years.
no
Metamorphic rocks are often found deep under the earth's surface because metamorphic rocks form from heat and pressure. Therefore, they form while they are under the earth's surface.

Because rocks are formed deep in the Earth, and sometimes by compressed sand other sedimentary material.
they have used two methods direct and indirect. seismic waves are the forces produced when earthquakes occur.from rocks from deep inside earth they can give inferences about conditions deep inside earth. they also record the seismic waves and record how dast they travel through Earth this is an indirect method

The Earth's crust does have sedimentary rocks in it's structure - limestone, slate, chalk, are three examples of commonly found sedimentary rocks.
