Sedimentary Rocks
Sedimentary rocks are formed by
What is the deposition of sediments in layers over long periods of time?
Igneous rocks are formed by
What is the melting and cooling (crystallization) of magma or lava?
Metamorphic rocks are formed by
What is existing rock undergoing intense heat and pressure?
These are formed under Earth's surface by the cooling/crystallization of magma
What is an intrusive igneous rock?
Coal is often found here
Where are the locations of ancient swamps?
TWO examples of sedimentary rocks
What are shale, limestone, conglomerate, sandstone, etc?
TWO examples of igneous rocks
What are pumice, obsidian, granite, etc?
TWO examples of metamorphic rocks
What are gneiss, marble, schist, etc?
These are formed above Earth's surface by the cooling/crystallization of lava
What is an extrusive igneous rock?
Uranium is often found here
Where is Australia?
Sedimentary rocks look like
What are straight, horizontal layers stacked on top of each other?
Igneous rocks look like
What is glassy or smooth, with possible large crystals depending on cooling time?
Metamorphic rocks look like
What are wavy, ribbon-like layers?
What is no rocks could melt to form magma, meaning no new igneous rocks could be formed?
This natural resource is typically found in temperate climates with relatively mild temperatures and high precipitation
What is fertile soil?
Sedimentary rocks often have something not found in any other type of rock
What are fossils?
The crystal size of igneous rocks is determined by
What is how quickly lava or magma cools?
What is underground?
If Earth's interior was cold instead of hot, the formation of metamorphic rocks would be affected by
What is the heat needed to form metamorphic rocks through heat and pressure would no longer be available, meaning no new metamorphic rocks could be formed?
What are human settlement, jobs, trade, conflict & war, or wealth & quality of life?
