Types of Rocks
How is igneous rock formed?
When 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 water evaporates, leaving minerals behind.
What is the movement of sediment called?
Erosion
What are two ways rocks can undergo metamorphism?
Contact Metamorphism and Regional 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
Rock that is found inside a volcano is made from this type of molten rock.
Magma
Crystal size when magma or lava cools quickly.
Small or no crystals
Sandstone, a sedimentary rock, must go through what processes to become slate, which is a metamorphic rock.
Heat and pressure
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 process where rock is changed because of pressure between two tectonic plates.
Regional metamorphism
Name an example of an extrusive igneous rock. (Hint...one floats...the other looks like black glass.)
Obsidian, pumice
This is formed when rocks go under a lot of heat and pressure.
Metamorphic rock
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
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'?
