1. It’s a Hard Rock Life! Alma Reyes, Madison Sorrells, Hannah Settle, Shelana Arif Rock Cycle

2. Igneous Facts: Near volcanos Formed by solidified molten rock Cools when reaches surface Examples: Granite Basalt

3. Metamorphic Facts: Formed when other rocks are changed by heat, pressure, and chemical action. Examples: Marble Gniess

4. Sedimentary Facts: Formed when combinations of rock fragments, seashells, and chemicals are compressed in layers and hardened. Examples: Limestone Sand stone

5. Magma Rocks form in layers. It starts from the magma chamber then flows up. It goes in between all the layers and goes up into the earths surface. And forms rock. Some rocks form under ground, the layers compress together and make rock.

6. Physical properties of rocks Rocks can be identified by their physical properties. Different physical properties include: 1.Luster 2.Streak 3.Hardness 4.Color 5.Texture Each physical property can identify weather it is sedimentary, igneous, or metamorphic

7. Rock Cycle Stages 1.Magma comes up from underground 2.Cools down and turns into igneous 3.Heat and pressure turn igneous into metamorphic 4.Breaks down and turns into sediment 5.compacts and turns into sedimentary

8. Rock Cycle Magma cools then turns into igneous, when its weathered it turns into sediment, compacting makes the sediment turn into sedimentary rock the heat and pressure turns it into metamorphic rock. Then that’s the rock cycle!!

9. How rocks are made Rocks are formed and made in many different ways and many different times. Rocks take at least millions to thousands of years to form. Different rocks form different ways sedimentary: formed when combinations of rock fragments are compressed together. metamorphic: formed by heat and pressure. igneous: formed when molten rock reaches the earth surfaces and cools.

10. Extra Information The rock cycle never stops. All rocks can be heated When Earths tectonic plates move around, they produce heat. When they come together, they make mountains and build rock. Rocks are made mostly of minerals or can be made of one mineral only.
