Types of Rocks
How is igneous rock formed?
Magma cools and solidifies.
The building blocks of rocks.
Minerals
These are rocks that can become metamorphic rocks.
Any rock type
The three categories all rocks can be put into.
Igneous, sedimentary, and metamorphic
What word means 'not alive'?
Inorganic
This type of rock is formed when sediment is compressed
Sedimentary
What is the movement of sediment called?
Erosion
What are two ways rocks can undergo metamorphism?
What type of Igneous rock is created inside the Earth?
Intrusive igneous rock
What word means 'a solid, inorganic substance of natural occurance'?
Mineral
Molten Rock that is found inside a volcano is called...
Magma
Crystal size when magma or lava cools quickly.
Small or no crystals
Sandstone, a sedimentary rock, must go through what processes to become magma
Melting
What is the process called when we talk about changing one type of rock into another types?
Rock cycle
What part of the word Metamorphic means 'to change'?
Morph
Igneous rocks can be classified into these two types.
Intrusive and extrusive rocks
Name the rock that is changed because of pressure between two tectonic plates.
Metamorphic Rock
Name an example of an extrusive igneous rock. (Hint...one floats...the other looks like black glass.)
Obsidian, pumice
What is the difference in crystal between intrusive and extrusive igneous rock?
The size of the crystals
Intrusive made in the volcano
Extrusive made out of the volcano
What words means 'the movement of large pieces of the Earth's crust'?
Plate tectonics
How are contact Metamorphic rocks created?
When magma touches rock, causing the heat to change the rock.
In which type of rock would I find a fossil?
Sedimentary Rock
Name the two process for how Metamorphic rock changes into a Sedimentary rock
Weathering into sediments
Then being compacted and cemented.
What type of igneous rock cool rapidly causing little to no crystals?
Extrusive igneous rock
What word means 'raising of the Earth's surface by the collision of tectonic plates'?
