How do plants most commonly break large rocks into smaller pieces?
Seeds from plants fall onto rocks and release acidic compounds.
Plant roots grow into cracks in rocks.
Stems of plants surround and squeeze rocks.
Plant protects surrounding rocks from extreme temperatures.
Hillsides are sometimes terraced to grow plants. What is the purpose of using terraces?
to keep roots from spreading
to increase wind erosion
to retain soil and water
to provide protection from animals
Which of the following statements does NOT illustrate the effects of human activity in creating erosion problems?
Building roads can increase erosion due to the change in drainage patterns.
Terracing along a mountainside can lead to erosion
Building on steep slopes can lead to landslides.
soil can be washed away from new construction sites due to clearing trees and brush
Which of the following causes of the Dust Bowl were due to HUMAN IMPACT?
- Over-tilling the land
- Severe heat and drought for almost a decade
- Overgrazing of farm animals
- High winds in the area
All answer options
1 and 3
1, 2, and 3
1 and 2
Which soil conservation practice aims to keep nutrients in the soil?
no-tilling farming
crop rotation
contour plowing on hillsides
terracing hillside farms
The rate of soil erosion will be higher in a field of crops planted in rows than in a field covered with grass because
grass grows lower to the ground than most crops
more soil is exposed to wind and water
most crops grow lower to the ground than grass
less soil is exposed to wind and water
Which of the following soil types would contain the most nutrients?
soil that has many large rock particles
soil that allows water to drain very quickly through it
soil with a lot of decomposed organic material
soil with a bedrock that is very close to the surface
The layer in the soil profile that has the most humus is

Which statement best describes soil formation?
it occurs primarily through leaching
the "parent rock" helps determine what type of soil forms
It is a completely inorganic process (not from living matter)
it occurs more quickly in dry climates
A scientist is studying geologic formations in deserts. During the study, the scientist draws a diagram of a canyon that has a unique shape.
Which of these BEST explains why the canyon has a unique shape?
The layers of the canyon are composed of different rocks and erode at different rates
The canyon is located in an area next to a river; the bottom layers experience more erosion than the upper layers
All layers of the canyon erode at the same time
The canyon is located in an area that receives heavy rainfall; erosion occurs more quickly due to the constant exposure of water
Which geologic processes have changed the landscape of Georgia the most during the last 10,000 years?
continental drift and plate movement
glacial erosion and deposition
water erosion and deposition
volcanoes and faulting
Which best describes the surface of the earth over billions of years?
High mountains gradually wear down until most of the earth is at sea level
High mountains stay side by side for billions of years with little change
Flat surface is gradually pushed up into higher and higher mountains until the earth is covered with mountains
High mountains gradually wear down as new mountains are continuously being formed, over and over again
The picture shows a kind of glacier that can be many meters thick. In this landscape, which of the following is most likely directly affected by this kind of glacier?
The average height of plants on the mountainside
the average mass of trees near the lake
the shape of clouds that form above the glacier
the shape of the valley between the mountains
Which of the following is the most important factor in erosion (transportation) of soil?
none of the choices
wind
glaciers
water
Which of these processes describes how sand is deposited on beaches?
waves carry sand to the beach and the sun dries the water, leaving sand behind.
Wind and waves grind up rocks under the beach into grains of sand.
Wind carries sand onto beaches from the land and then levels it out.
waves carry sand up the sloping beach, depositing sand as the waves lose speed.
In Spring 2003, a natural rock outcropping in New Hampshire called the Old Man of the Mountain collapsed. Which of the following most likely loosed the rock and caused it to fall?
oxygen reacting with iron on the surface of the rock
heat turning sedimentary rock into metamorphic rock
volcanic activity producing pressure at the rock's base
water freezing and thawing inside cracks in the rock
