high winds
B
running water
C
earthqakes
D
erupting volcano
2) When rocks and soil are moved from one place to another it is called
A
compaction
B
weathering
C
deposition
D
erosion
3) The best statement to describe chemical weathering is
A
Limestone gravestones in Georgia dissolve in acid rain
B
Stone mountain breaks apart in large sheets due to rock expansion and erosion called exfoliation
C
running water carves a valley through a mountain range over millions of years
D
wind causes the formation of arches in the rocks at Big South Fork in Tennessee
4) Chemical weathering differs from mechanical weathering in that...
A
chemical weathering happens over a much shorter period of time than mechanical weathering
B
chemical weathering occurs in mountains; mechanical weathering occurs on flat surfaces
C
chemical weathering happens in the tropics; mechanical weathering happens in more temperate climates
D
chemical weathering changes the chemical make-up of materials; mechanical weathering breaks the rock into smaller pieces
5) A crack in a sidewalk is observed over 3 years. Year 1 the crack was 1.9cm, year 2 was 4.2cm, and year 3 was 6.1cm. How can this data best be explained?
A
wind blows across the crack in the fall
B
rain falls into the crack in the spring
C
rocks fall in the crack during the summer
D
ice forms in the crack during the winter
6) A picture of a marble statue taken in 1800 when it was first built is compared to a recent photo. The stature looks different today. What best explains why the statue looks different?
A
the statue was exposed to sunlight
B
the statue was exposed to increasing air temperatures over time
C
the statue was exposed to chemical weathering
D
the statue was in a museum for 95 years
7) Stone Mountain is one of the largest exposed pieces of granite in the world. Granite is an intrusive igneous deep beneath Earth's surface. How can the exposure of Stone Mountain best be explained?
A
magma reached Earth's surface and hardened into granite.
B
Stone Mountain is on a transform boundary and movement caused it to be exposed
C
weathering and erosion of Earth's surface exposed the rock
D
Chemical weathering of Earth's surface exposed the rock
8) Weathering breaks down rock chemically and physically. Which of the following is a cause of chemical weathering?
A
acid rain
B
tumbling rocks in a river
C
plant roots growing in cracks of rocks
D
water freezing and thawing
9) When rocks are broken into small pieces, what happens to these pieces?
A
they turn into earthworms
B
plants use the pieces for energy
C
they become part of the soil
D
animals use them for food
10) In cold climates, the action of water breaks rocks into small pieces which helps form soil. What causes the rocks to break?
A
alternate freezing and thawing mechanically weathers rock
B
minerals leaching from the rocks
C
decomposition due to the action of animals
D
the reaction of acidic ice with calcite chemically weathers rock
11) How is a river responsible for shaping a canyon?
A
the weight of a river creates a depression in the ground, forming a canyon
B
a river erodes the rock forming a canyon
C
a river deposits material on its banks which will lead to the formation of a canyon
D
the placement of dams along a river will lead to the formation of a canyon
12) As a river erodes and deposits sediment on its banks, what happens to the river as erosion, deposition continue for a long period of time?
A
a change in the path the river takes
B
an increase in the fish population
