Weathering
The breaking down of rock into smaller pieces called sediments.
What is Weathering?
The carrying away of weathered pieces of rocks, or sediments, by wind, moving water, gravity, or ice.
What is Erosion?
The laying down of weathered pieces of rock, or sediments, in a new location.
What is Deposition?
The three kinds of mineral material found in soil.
What are Sand, Silt, and Clay?
Resources on Earth are _________, which is why conservation, or the careful management and usage of Earth's resources, is important.
What is Limited?
The type of weathering responsible for cracks in a sidewalk caused by growing weeds.
What is Mechanical Weathering?
The four agents, or causes, or erosion.
What are Wind, Water, Gravity, and Ice?
The natural process that causes the deposition of sand along shorelines, creating beaches
What are Waves/Currents?
This layer of soil contains the most rocks and least amount of organic matter.
What is Bedrock?
This type of renewable energy source harnesses the power of the sun to generate electricity and reduce dependence on fossil fuels.
What is Solar Energy?
The type of weathering associated with acid rain.
What is Chemical Weathering?
When gravity causes the rapid movement of sediments, rocks, and/or other debris down a slope.
What is a Landslide?
Where a river meets a body of water, such as an ocean or lake, and the water slows down, depositing sediments
What is a River Delta?
This layer of soil contains the highest concentration of organic material and nutrients.
What is Topsoil?
Energy sources like wind, solar, and hydroelectric power are examples of this type of energy because they can be replenished naturally in a human lifetime.
What are Renewable Energy Sources?
The specific type of mechanical weathering that formed the Hoodoos of Bryce Canyon.
What is Ice Wedging/Frost Wedging?
This agent of erosion is active on Earth, but not on Mars.

What is Moving Water?
These islands are formed by the deposition of sand and other materials along coastlines.
What are Barrier Islands?
The layer of soil beneath the topsoil, consisting of mostly minerals and little organic material.
What is Subsoil?
What are three fuels that require burning to release energy and also create air pollution? As a group, they are referred to as "fossil fuels."
What are Coal, Oil, and Natural Gas?
The process where minerals in rock, especially iron, react with oxygen in the air or water to form rust, which chemically weathers the rock.
What is Oxidation?
Clay-sized sediments packed tightly together would experience more or less erosion than sand-sized sediments loosely packed together?
What is Less Erosion?
A type of landform created by the deposition of sand by wind in dry areas.
What are Sand Dunes?
In our soil columns lab, Soil A, our sandy/pebbley soil, ______ after 5 minutes due to its ____ density, and Soil B, rich in organic material, __________ after 5 minutes due to its _____ density.
What is Sank/High and Floated/Low?
Deforestation can cause an ________ in soil erosion.
What is an Increase?
