Rock type: Igneous?

They form from the cooling of magma deep inside the earth. They often have large crystals you see them with the naked eye. Are formed when rock is super-heated and becomes molten liquid. There are two kinds of molten rock magma found beneath the earth’s surface and lava found on earth’s surface.

The molten rock cools and hardness on or beneath the earth’s surface forming a variety of igneous rock two type of rock are called the granite rock and the other is called the basalt rock. Metamorphic? They are formed through the change of igneous and sedimentary rocks. They can form both underground and at the surface. Are rocks that have been changed under great heat and pressure.

The original rock can be sedimentary, igneous or even metamorphic the original rock is changed into something new, just as a caterpillar metamorphic into a butterfly. Sedimentary?): they are formed through the solidification of sediment. They can be formed from organic remains such as limestone or from the cementing of other rocks.

Are made of smaller pieces like sand or mud, called sediments that pile into layers as pressure on the sediment increases over time minerals are like glue cementing them into solid rocks. Sandstone, limestone, shale, mudstone. Description (3 sentences or more): Chart is a microcrystalline or cryptocrystalline sedimentary rock material composed of silicon dioxide coal is an organic sedimentary rock that forms mainly from plant debris.
