the rock cycle ms. sikes. rock cycle continual process by which new rock forms from old rock
TRANSCRIPT
3 types of rock1. Igneous: formed from cooling magma
1. Can be intrusive (formed inside the earth or extrusive (formed on the surface of earth)
2. Sedimentary: formed from layers being smushed together (usually under water)
3. Metamorphic: changed by heat and pressure (usually formed under the earth’s surface)
Important Vocab
• Weathering: when water, wind, ice and heat break down rock
• Erosion: the process by which wind, water, ice or gravity transports soil and sediment from 1 place to another
• Depostion: when sediment is is deposited (laid down) somewhere
The Rock Cycle
• 1:Rock that is buried under ground melts because the center of the earth is so hot.
• 2: magma rises and cools off = solidifies into IGENOUS ROCK (this can happen during a volcanic eruption)
The Rock Cycle
• The Igneous rock is weathered away over time. Erosion takes the sediment to other places and deposits them somewhere else like the ocean
• The water compacts the pieces into SEDIMENTARY ROCK
The Rock Cycle• When Earth’s plate’s collide,
some of Earth’s crust is forced down.
• It’s HOT down there!
• The heat and pressure squeeze the rock and change it to METAMORPHIC ROCK.
• Then it starts all over again…
• 2. Sedimentary rock falls through the cracks when the plates move and collide. What happens to this rock?
3. A volcano erupts and magma spills out. What will happen to this magma? What type of rock is formed?
