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

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 best describes the surface of the earth over billions of years?

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 average height of plants on the mountainside
the average mass of trees near the lake

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

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
the process of wearing down by friction - like sand blasting
exfoliation
abrasion
erosion
deposition
The photograph shows scratched and grooved
bedrock with boulders on its surface. The scratches and grooves were most likely created when
alternating thawing and freezing of water cracked the bedrock
flooding from a nearby lake covered the bedrock
a glacier dragged rocks over the bedrock
rocks from a landslide slid along the bedrock
The photograph shows a valley. Which agent of erosion most likely produced this valley's shape?
blowing wind
ocean waves
moving ice
running water
Which statement best explains why this process results in weathering?
