Chapter 3 Section 3.2 Igneous Rocks Worksheet Answers [extra Quality] Direct

List three examples of intrusive igneous rocks. Answer: Granite, Diorite, Gabbro.

Answer: a) Phaneritic

The formation of igneous rocks involves the cooling and solidification of magma or lava. Magma is a molten mixture of minerals, gases, and rock fragments that forms beneath the Earth's surface. When magma cools, the minerals start to crystallize, and the rock begins to solidify. The rate of cooling determines the texture of the rock, with slower cooling resulting in coarse-grained rocks and faster cooling resulting in fine-grained rocks. chapter 3 section 3.2 igneous rocks worksheet answers

Igneous rocks exhibit a range of characteristics, including: List three examples of intrusive igneous rocks

Describe the relationship between cooling rate and crystal size. Answer: Slow cooling (magma deep underground) allows time for large crystals to grow (coarse texture). Fast cooling (lava at the surface) results in small or no crystals (fine or glassy texture). Magma is a molten mixture of minerals, gases,
