The material that makes up the solid parts of Earth Rocks The material that makes up the solid parts of Earth

3 types of rocks Igneous- forms when magma, or molten rock, cools and hardens. Magma is lava when it is exposed at the Earth’s surface. Sedimentary- when rocks and other organic matter have been broken down into smaller fragments by erosion and are compressed together Metamorphic- undergo tremendous pressure and extreme heat to change or alter an existing rock

Igneous Rocks Intrusive- The magma that forms these rocks intrudes, or enters into other rock masses beneath Earth’s surface. The magma cools at a slow rate and then hardens Extrusive- When magma reaches the Earth’s surface it cools at a rapid rate and forms crystals

Textures of Igneous Rocks Coarse-Grained Igneous Rock- Intrusive igneous composed of large mineral grains Fine-Grained Igneous Rock- Extrusive igneous composed of small mineral grains that cannot be seen with the naked eye Other Igneous Rock textures- when magma cools slow at first and then cools more rapidly as it nears Earth’s surface. Composed of Large crystals embedded within a mass of smaller ones.
