Igneous
Igneous rocks are formed from?
Hardened magma
What is compaction?
Compaction is when sediments are layered on top of each other
How are metamorphic rocks formed?
Existing rock changed by heat and/or pressure
Which type of rock is made when layers of sediments are compacted and cemented?
Sedimentary rocks
The area below the Earth's crust is called?
Mantle
The process magma takes to become igneous rocks is called
Cooling
What is the difference between compaction and cementation?
Compaction is when sediments are layered on top of each other
Cementation is when sediments are glued together
In order for metamorphic rocks to form they must be uplifted/subducted?
subducted
Uplift is the process of?
A plate moving upwards
The study of rocks, their history and the processes that form and change them.
Geology
As sedimentary rocks are subducted they are exposed to energy from_______
Earth's interior
How are sedimentary rocks formed?
sediments are compacted and cemented
The difference between metamorphic and igenous rocks?
Metamorphic rocks do not melt to magma; igneous rocks do melt into magma
Rain, wind, ice
Give an example of how an engineer's mistake involving rocks could harm people.
Along the lines of - if an engineer did not learn about rocks they may not be able to support structures that could break or collapse
As metamorphic rock is melted and cooled what happens?
The rock becomes magma then becomes igneous rocks
Energy from the _____ exposes sedimentary rocks to ______ creating sediments
Sun; weathering
How can we see metamorphic rocks on the surface?
Erosion is the process of
Moving sediments from one location to another
This person made this quote famous "Do you smell what the Rock is cooking?!"
Dwayne "The Rock" Johnson
What is the difference between magma and lava?
Magma is molten rock found below the earth's surface.
Lava is molten rock found above the earth's surface
What are the processes that create sedimentary rocks?
Weathering, (erosion), compaction & cementation
What are the the processes that create metamorphic rocks and the process where we can see it on Earth's surface?
Subduction, heating/pressure, (uplift), (weathering)
igneous rocks, sedimentary rocks, and metamorphic rocks
Physical weathering is when rocks are broken down by nature such as rain, wind, or ice. What do you think biological weathering is?
Break down of rocks through living organisms
