Which type of rock is formed from the cooling of molten magma?

  1. Granite

  2. Basalt

  3. Sandstone

  4. Limestone

The correct answer is: Granite

Granite is the type of rock formed from the cooling of molten magma. This is because magma, which is molten rock beneath the Earth's surface, cools slowly and solidifies into large, interlocking crystals that make up granite. Basalt may appear similar to granite, but it is formed from lava, which cools quickly on the Earth's surface and does not have the same interlocking crystal structure. Sandstone and limestone are both sedimentary rocks that are not formed from molten magma, but rather from the accumulation and compression of sediment or organic matter. Sandstone is made up of compressed grains of sand, while limestone is primarily made of calcium carbonate deposits from ancient sea creatures. Therefore, A) Granite is the only choice that accurately describes a type of rock formed from the cooling of molten magma.
