True or False
A slower moving river will have more curves and bends to its shape as it changes.
True.
200
True or False
Moving water is only a slow process that changes the earth.
False. It can be both fast and slow depending on how fast and how much water is moving.
200
True or False
An earthquake occurs when plates get stuck against each other, build up tension, and then move quickly to release a large amount of energy.
True
200
How can a plant both slow down erosion and speed up weathering?
It can slow down erosion by holding soil together with its roots, but also speed up weathering by growing its roots in rocks and breaking them apart.
300
Identify the main process and the main physical cause that would form a sea arch.
a) erosion and wind
b) erosion and water
c) deposition and wind
d) weathering and ice
b) erosion and water (waves)
300
Wind can cause erosion. Identify which of the following choices is an example of a slow change to Earth's surface cause by erosion from wind.
a) tides
b) moraines
c) sand dunes
d) windmills
c) sand dunes
300
Give three examples of rapid processes that shape the earth.
*Many possible answers including, but not limited to: volcanic eruptions, tornadoes, fires, mudslides, landslides, earthquakes, floods, and more.
300
A growing pile of sediment deposited at the mouth of a river is called a _____________.
A growing pile of sediment deposited at the mouth of a river is called a delta.
300
How does a river delta form?
It is formed from sediment deposition from moving water in the river.
400
What process and what main item caused the change of creating a glacial moraine on the Earth’s surface?
deposition from ice
400
Describe the purpose of one of our labs or demonstrations in class.
*Many to note: Oreo lab, glaciers ice cube, wind and water "mountain" erosion, cave formation, sand dune and beach creation...
400
Give three examples of slow changes to the Earth's surface.
*Many possible answers including: weathering, erosion, mountain formation, volcano formation, arch formation, deltas, etc.
400
A landslide is typically caused by ___________ and _____________.
A landslide is typically caused by rain and gravity.
400
Sand dunes often have a wavy surface. What creates this kind of surface?
a) rain water
b) wind blowing
c) animals leaving tracks
d) vibrations from earthquakes
b) wind blowing
500
List the four main causes of erosion.
Flowing water, wind, gravity, and glaciers

Describe how a canyon is formed. Use scientific words in your description.
Over a long period of time, moving water from a river will carve out and weather the rock on the walls of the river. The water will erode the rock and sediment away.
500
Explain what would happen if water got into the crack of a mountain in a cold environment. Be specific and don't skip steps.
The water would freeze then the ice would expand causing the crack to become larger and possibly break off or fall apart (weather).
500
Why are stones typically smooth on the beach?
The continuous movement from the waves have weathered them away and smoothed them out.
500
Explain how a giant boulder may have ended up in the middle of a field or forest.
It's possible that it was stuck in or on a glacier that transported it around and then the glacier melted somewhere, which then deposited the boulder.
