The Rock Cycle Formation of the Earth
What a rock? A rock is a solid material made up of one or more minerals Mineral: a solid element or compound found in the Earth s crust, that has the same definite crystal shape and chemical formula
Igneous Rocks Igneous rocks are formed when magma or lava cool Magma: molten rock below Earth s surface Lava: molten rock above the Earth s surface
Igneous Rocks What do you notice about these rocks? What is the same about all of them? What are some of the physical properties of igneous rocks from what you see?
Sedimentary Rocks Sedimentary rocks are formed from sediments being squished together Sediments: tiny particles of rocks, minerals, plants, bones, or shells
Sedimentary Rocks What do you notice about these rocks? What is the same about all of them? What are some of the physical properties of sedimentary rocks from what you see?
Metamorphic Rocks Metamorphic rocks are formed from igneous or sedimentary rock is changed by pressure or heat
Metamorphic Rocks What do you notice about these rocks? What is the same about all of them? What are some of the physical properties of metamorphic rocks from what you see?
Playdoh Activity What did you notice? How does this model what happens to rocks during the rock cycle? What was similar in different between each of the rocks ?
