1. Rocks and The Rock Cycle Rock is a solid material made up of one or more minerals or other substances, including the remains of once-living things.

2. Types of Rocks 1)Igneous Rock 2)Sedimentary Rock 3)Metamorphic Rock

3. Igneous Rock Igneous rock forms when magma or lava cools and hardens.

4. Igneous Intrusive Rocks are formed from magma beneath the surface. gabbo granite pegmatite diorite

5. Igneous Extrusive Rocks are formed from lava on the surface andesite pumice scoria obsidian

6. Sedimentary Rock Sedimentary rock forms when particles of rock and other materials are pressed and stuck together Erosion moves sediment from place to place on Earth’s surface. Sediment is laid down in a process called deposition. Slowly thick layers of sediment build up and the weight of the layers above presses down on the layers below. The process is call compaction, squeezes the layers of sediment together. Another process, called cementation, glues the sediment together.

7. Three major types of sedimentary rocks 1. Clastic rocks are pieces of rocks that have been pressed and stuck together. siltstone conglomerate

8. 2.Organic rock are formed from the remains of plants and animals. limestone coal

9. 3. Chemical Rock areformed when dissolved minerals come out of solutions and form crystals. iron ore rock salt

10. Metamorphic Rock Heat and great pressure deep beneath Earth’s surface can change rock to metamorphic rock Sometimes heat from a volcano causes nearby rock to become metamorphic rock

11. Metamorphic Rocks granite becomes gneiss sandstone becomes quartzite

12. The Rock Cycle Forces inside Earth and the surface produce a rock cycle that builds, destroys, and changes the rocks in the crust. Forces inside Earth and the surface produce a rock cycle that builds, destroys, and changes the rocks in the crust. The rock cycle is a series of processes on and beneath Earth’s surface that slowly change rocks from one kind to another. The rock cycle is a series of processes on and beneath Earth’s surface that slowly change rocks from one kind to another.

13. Igneous, sedimentary, and metamorphic rocks change continuously through the rock cycle
