Sediments are transported or moved form their original source by a process called
Deposition
Erosion
Uplift
weathering

2. Standard:
Summarize the basic events that occur during the rock cycle.

3. Objective
1. I can describe 4 processes that shape Earth’s features. 2. I can describe how each type of rock changes into another type of rock. 3. I can describe how igneous, sedimentary and metamorphic rocks are formed.

5. Guiding Questions What is a rock? How are rocks formed?
How do igneous, sedimentary and metamorphic rocks form?

6. Rocks
A rock is a naturally occurring solid mixture of one or more minerals and organic matter. It might be hard to believe but rocks are always changing…..

10. Which rock will it stay? Can you Figure it Out?

What is the Rock Cycle ?
The rock cycle is a sequence of events involving the formation, alteration, destruction, and reformation of rocks as a result of natural processes such as magmatism (melting of rock into magma), erosion, transportation, deposition, lithification, and metamorphism.
Glossary of Geology, Bates & Jackson, AGI
A possible sequence involves the crystallization of magma to form igneous rocks that are then broken down to sediments (clasts) as a result of weathering, the sediments later being lithified to form sedimentary rocks which are in turn altered by heat, pressure and or fluids to become metamorphic rocks.
The rock cycle can also be related to plate tectonics, if that is appropriate at this time.

14. Middle School Science
Nature and Technology - Changing the Earth
The mantle, crust and surface of the earth can be thought of as a giant recycling machine;
rocks are neither created nor destroyed, but redistributed and transformed from one rock type to another.

17. Minerals combine to form Rocks

18. Some Rocks are made up of just one mineral - like rock salt (made up of the mineral halite)
Others Rocks are made up of many minerals - like the granites and gneisses (made up of feldspars, quartz, and other minerals)

35. Science Closure Which best describes one way igneous rocks form?
Sedimentary rocks erode.
Sedimentary rocks are compacted.
Metamorphic rocks are melted, then cooled.
Metamorphic rocks are deposited and cemented.
