Question

what are lgneous .metamorphic and sedimentary rocks? Give an example of each of them?​

Answer 1

Answer:

Igneous rock is formed when magma or lava from volcanoes cools. ...

Sedimentary rocks are formed over millions of years when sediments (tiny pieces of rocks and animal skeletons) are pressed together at the bottom of seas and rivers.

Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors

Examples include sandstone, coal and chalk. Some sedimentary rocks contain fossils (bones or shells of living things that were buried long ago and have turned to stone). Metamorphic rocks are formed when other rocks are changed due to heat or pressure. Examples include slate and marble.
