A
Molten rock within the earth
What is magma or intrusive rock?
Was once an igneous or sedimentary rock and has been changed as a result of intense heat and pressure within the Earth's crust.
What is a metamorphic rock?
What is heat and pressure?
When wind, water, ice removes sediment down to a new location
What is erosion?
The squeezing of sediments by the weight of the rocks and sediments above them.
What is compaction?
granite, pumice, obsidian
What are igneous rocks?
Rocks formed from extreme heat and pressure
What are metamorphic rocks?
The process that turns any rock into magma
What is melting?
When an igneous rock changes into a sediments
What is weathering and erosion?
The temperature of magma decreases can occur underneath or on top of Earth’s surface
What is cooling?
These are created from weathering and erosion
What are sediments?
When sediment is dropped into a new location
What is deposition?
When metamorphic rocks break down into sediments
What is weathering and erosion?
When loose sediments are compacted into layers and harden through cementation
What are sedimentary rocks?
Fluids that binds sediment together
What is cementation?
Strong forces that change rocks into metamorphic rocks
What is heat and pressure?
When sediments form into sedimentary rock
What is compaction and cementation?
This is formed when lava cools on the outer surface of earth's crust
What are extrusive rocks?
shale, limestone, gypsum, sandstone
What are sedimentary rocks?
These rocks are formed when magma cools within the earth's crust
What are intrusive rocks?
This is needed in order for igneous rocks to form
What is a volcano?
What is magama and lava?
When molten magma cools.
What are igneous rocks?
Includes more than one mineral deposit and can be either glassy or coarse.
What is an igneous rock?
Wind, rain, plants or animals break down rocks into smaller pieces and turns it into sediment
What is weathering?
marble, slate, quartzite, gneiss
What are metamorphic rocks?
