Types of Rocks
What are the three major rock types?
Igneous
Sedimentary
Metamorphic
Which type of rock forms from cooled magma and lava?
Igneous
Igneous rocks form from:
Cooled magma and lava
What are sedimentary rocks made of?
Sediments
Where do Metamorphic rocks form?
Deep within Earth
Granite is an example of which type of rock?
Igneous
Which process breaks rocks into smaller pieces?
Weathering and erosion
What are the two TYPES of Igneous rock?
Intrusive and Extrusive
Which part of the Sedimentary rock process moves sediment from one location to another?
Transportation
Metamorphic rocks form when existing rocks are changed by:
Heat and Pressure
A rock that has visible layers (parts), is most likely what type of rock?
Sedimentary
Which type of rock forms when heat and pressure change an existing rock?
Metamorphic
A type of Igneous rock that forms from lava on Earth's surface is called:
Extrusive rock
What are the three most common sedimentary rocks?
Shale
Sandstone
Limestone
What is a common Metamorphic rock that it used inside homes/houses?
Marble
Which rock is most likely to contain fossils?
Sedimentary
Heat and pressure deep within Earth can cause rocks to:
Change into Metamorphic rock
Slow cooling of magma underground produces crystals that are:
Large (coarse grained)
What other materials, other than small particles of rocks or minerals, make up Sedimentary rocks?
Marble forms from which rock?
Limestone
What determines the type of rock?
Origin (How it forms)
What TYPE of rock forms when magma cools BELOW Earth's surface?
Intrusive Igneous rock
What is the most common extrusive igneous rock that makes up a large part of Earth's oceanic crust?
Basalt
What is the process, in order, that forms Sedimentary rocks?
Weathering and Erosion
Transportation
Deposition
Compaction
Cementation
Foliation in Metamorphic rocks refer to:
Visible layers (bands)
