These rocks are formed by the cooling and solidification of molten magma flowing from the interior of earth during volcanic eruption.



These rocks often contain crystals of different minerals.Granite and basalt are examples of Igneous Rocks.

Metamorphic Rocks


Metamorphic rocks are formed out of Sedimentary and Igneous Rocks under extreme heat and pressure conditions.Thus, the Metamorphic Rocks are the altered forms of Igneous and Sedimentary Rocks.Granite for example changes into Gneiss and Coal into Diamond. bro mark me as brainliest

Heya mate ❤

Here's ur answer -

METAMORPHIC ROCKS :

Metamorphic rocks are rocks that have changed as a result of exposure to extreme pressure and heat. The term “metamorphic” itself is the combination of the Greek words meta, which means “after,” and morph, which means “change.” Intense temperatures and pressure beneath the earth cause physical and chemical change to igneous and sedimentary rocks, causing them to form metamorphic rocks. Marble comes from limestone, while slate is formed from shale or mudstone. These rocks are formed either by being subjected to great pressure beneath the earth (regional metamorphism) or by magma coming into contact with the rocks.

SEDIMENTARY ROCKS :

Sedimentary rocks are made from sediments. Small rock particles, dead animals, plants, and other microorganisms settle at the bottom of lakes and oceans to form sediments. The most common sedimentary rocks include sandstone, shale, and limestone.

About 75% to 80% of the earth’s land mass is composed of sedimentary rocks. The earth’s crust, however, is made up of only 5% sedimentary rocks. Shale is the most abundant type of sedimentary rock, followed by sandstone and carbonate
