Rock Types
This rock forms when lava cools after a volcanic eruption.
What is igneous rock?
The “W” in W.E.D. stands for this process that breaks down rocks.
What is weathering?
Cutting down trees for space or resources is known as this.
What is deforestation?
These form where rivers meet oceans and deposit sediment.
What are deltas?
What is the cause of limestone cave formation?
Water dissolving limestone through chemical weathering
This type of rock forms through compaction and cementation of sediment.
What is sedimentary rock?
This process moves sediments from one place to another.
What is erosion?
These man-made structures can block water flow and create deserts.
What are dams?
These large formations are caused by convergent plate boundaries.
What are mountains?
Which landform is most likely created by wind erosion?
Desert sand dunes
This rock forms deep underground due to intense heat and pressure.
What is metamorphic rock?
This process drops or lays down sediment in a new location.
What is deposition?
This form of pollution causes acid rain that breaks down rock.
What is air pollution?
These landforms are created as glaciers move and crush rock below.
What are valleys or glacial grooves?
If vegetation is cleared and it rains, what increases?
Erosion
What must happen for sedimentary rock to become metamorphic?
What is heat and pressure?
Ice, wind, water, and gravity are agents of these two processes.
What are weathering and erosion?
When we replace nature with malls and roads, we call it this.
What is urbanization?
These sandy landforms form from wind erosion and deposition.
What are dunes?
What happens at point A to change metamorphic rock to igneous?
Melts & cools
Which two processes must occur for a metamorphic rock to become igneous?
What are melting and cooling?
This type of landform is created mostly by wind deposition.
What are sand dunes?
What happens to soil when trees are removed and it rains?
What is erosion?
This type of landform forms when groundwater fills a basin.
What is a lake?
Weathering, erosion, and deposition shape Earth by doing this.
Breaking down, moving, and laying down sediment
