What is it?
The breaking down of rock on Earth's surface into smaller pieces is called...
Weathering
True or False
Wind and water can carry sand and small pieces of rock to new locations.
True
Volcanoes change Earth's surface...(slowly/quickly)
Quickly
The difference between weathering and erosion is:
a. weathering causes a quick change in landforms and erosion causes a slow change in landforms.
b. weathering breaks rocks into sediments and erosion moves sediment from one place to another.
B
Small pieces that break off of rocks.
Sediments
What are mountains, hills, islands and other surface features of the land?
Landforms
Volcanoes, floods, tsunamis, and wildfires are _______. (slow or fast land changes)
Fast
Weathering changes Earth's surface...(slowly/quickly)
Slowly
The difference between Wildfires and Tsunamis is:
a. Wildfires are fast land changes and Tsunamis are slow land changes.
b. Wildfires happen on land and Tsunamis on water.
B
Gigantic formations of ice that do not completely melt over the course of a year.
Glaciers
The process by which weathered rock is picked up and moved to a new place.
Erosion
Weathering over long periods of time breaks rock into ____________ pieces. (larger or smaller)
smaller
True or False.
Erosion can change the shape of the land faster than a volcano can.
False
Name a difference between weathering and erosion.
Weathering makes things smaller, and erosion moves it.
Pulls rocks and soil downhill.
Gravity
Huge sheets of ice that move slowly over land.
Glaciers
Fast flowing rivers can pick up and carry rocks (far/short) distances.
Far
Water can weather rock by:
A. eroding soil
B. by freezing and melting
B. Freezing and melting
The difference between a mountain and a hill is:
a. A mountain is bigger than a hill and the hill has round top.
b. The hill is between two mountains and the mountain has a peak.
A
A quick movement of rocks down a slope.
Rockslide
The sudden movement of rocks and soil down the side of a hill because of gravity and rain.
Landslide
All of the following are forces that change landforms EXCEPT:
A. wind
B. moving water
C. glaciers
D. physical features
D. Physical features
Landslides are quick changes to the land. They can be caused by:
A. magma and rain
B. gravity and rain
Gravity and rain
The difference between fast and slow land changes is:
A. Fast land changes take years to happen and slow land changes happen in a moment.
B. When fast land changes occur people have to react immediately and in slow land changes people can see how land is changing over time.
B
Can cause eruptions of magma.
