Weathering, Erosion, and Deposition
What is weathering?
How is a metamorphic rock formed?
Heat and pressure
What layer of the earth is made up of tectonic plates?
Which name do we call the molten rock as it comes out of the volcano: lava or magma?
Lava
What makes an ore more special than a mineral?
We mine for them/They are expensive
Give an example of an agent of erosion.
Wind, Water, Gravity, etc.
How does sediment turn into sedimentary rocks?
Compaction and cementation
What causes tectonic plates to move?
Convection currents (in the Mantle)
What causes earthquakes?
Tectonic Plate movement
Name an example of an ore.
(Teacher will approve answers)
A canyon is the result of ___________
Erosion
What is the difference between extrusive and intrusive igneous rocks?
Extrusive: lava cools and hardens on surface
Intrusive: magma cools and hardens under the crust

What is an example of a renewable resource?
Solar energy, wind energy, geothermal energy, hydroelectricity
A rock breaks at the top of a hill. The pieces fall down the hill and land in a ditch at the bottom. Tell me which parts of this event represent weathering, erosion, and deposition.
Weathering: rock breaks
Erosion: pieces fall down the hill
Deposition: pieces settle in ditch
You take a sedimentary rock and throw it into a volcano where it melts. What type of rock will it form into next?
Igneous rock
Which type of plate boundaries are most likely to cause earthquakes?
Transform boundaries
What is the Ring of Fire and where is it?
The plate boundaries surrounding the Pacific Plate where many earthquakes and volcanoes happen
Why should we consider switching to an alternate energy source?
Fossil fuels are running out more quickly than they are being made.
