MS. UNDERBERGER MARCH 9, 2015 OPEN UP YOUR WORKBOOK TO PAGE 64 The Rock Cycle

What is the Rock Cycle? The rock cycle is a series of processes that occur on the Earth’s surface and in the crust and mantle that slowly change rocks from one kind to another Plate tectonics are responsible for the rock cycle

How do rocks change? Rocks can change through 5 processes 1. Weathering and erosion 2. Heat and pressure 3. Melting 4. Volcanic Activity 5. Deposition, Compacting, Cementation

1. Weather and Erosion Weathering- the effects of freezing and thawing, plants roots, acid, and other forces on rock Erosion- the process by which running water, wind, or ice carry away bits of broken rock Where does it fit in the cycle? when igneous rock, metamorphic rock, and sedimentary rock weather and erode, sediment is formed

2. Heat and Pressure Heat and pressure are forms of energy that can change the rock. Where does it fit in the cycle? Igneous rock and sedimentary rock need heat and pressure to become metamorphic rock When rock loses heat, it can create igneous rock

3. Melting Melting causes rock to turn from a solid into liquid magma and lava Where does it fit in the cycle? Metamorphic rock, igneous rock, and sedimentary rock all melt to become magma and lava

4. Volcanic Activity Volcanic activity involves the movement of lava and magma to turn a liquid to a solid. Where does it fit in the cycle? When volcanic activity occurs, igneous rock is formed

5. Deposition, Compaction, and Cementation Deposition is the process by which sediment settles out of the water or wind carrying it and falls Compacting: the process of pressing sediments together Cementation: dissolved minerals crystallize and glue particles of sediment together Where does it fit in the cycle? Sediments need deposition, compaction, and cementation to become sedimentary rock

Rock Cycle and Plate Tectonics Moving plates cause magma to form, which creates igneous rocks! The collision of continental plates can move a mountain range, causing weathering and erosion. This causes sedimentary rock! The collision of continental plates can push rocks beneath the surface. The heat and pressure pushing the rocks beneath the surface can create metamorphic rock!
