Igneous rocks
Sedimentary rocks
Metamorphic rocks

Give me the defination and three or four example of this​

Answer 1

Answer:

igneous rock

Igneous rocks is one of the three main rocks types . Igneous rocks are formed through the cooling and solidification of magma and lava .

sedimentary rocks

Sedimentary rocks are types of rock that are formed by accumulation or deposition of mineral or organic particles at the earth's surface followed by cementation.

metamorphic rocks

Metamorphic rocks make up a large part of the earth's crust and form 12% of the earth's Land surface. they are classified by texture and by chemical and mineral assemble .

Answer 2

Answer:

Igneous rock (derived from the Latin word ignis meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. ... Sedimentation may also occur as dissolved minerals precipitate from water solution.

Metamorphic rocks arise from the transformation of existing rock to new types of rock, in a process called metamorphism. The original rock is subjected to temperatures greater than 150 to 200 °C and, often, elevated pressure of 100 megapascals or more, causing profound physical or chemical changes.
