Detailed explanation-1: -There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers.
Detailed explanation-2: -The correct answer is option 1, i.e. Granite. Granite is an example of Intrusive Igneous Rocks. When molten magma cools it forms Igneous Rocks.
Detailed explanation-3: -There are two basic types: 1) intrusive igneous rocks such as diorite, gabbro, granite and pegmatite that solidify below the Earth’s surface; and 2) extrusive igneous rocks such as andesite, basalt, obsidian, pumice, rhyolite and scoria that solidify on or above the Earth’s surface.
