Weathering Weathering 2 Erosion and Deposition Erosion 2 Anything
100
What is WEATHERING?
This is the process in which materials on or near Earth's surface break down and change.
100
What is OXIDATION?
This is the chemical reaction of oxygen with other substances.
100
What is EROSION?
This is the removal of weathered rock and soil from its original location.
100
What is a GLACIER?
This is a large thick mass of ice that moves and erodes.
100
What is 10%?
This is the approximately the percentage of Earth's surface that is presently covered by glaciers.
200
What is MECHANICAL WEATHERING?
This is a type of weathering in which rocks and minerals break down into smaller pieces.
200
What is CLIMATE?
This characteristic of a region has a great effect on the rate of weathering.
200
What is DEPOSITION?
This happens when the materials are transported and dropped in another location.
200
What is WIND?
Sand dunes are formed by this erosional force.
200
What is MECHANICAL WEATHERING?
This process most likely produced the present appearance of the Arches National Park in Utah?
300
What is CHEMICAL WEATHERING?
This is a type of weathering by which rocks and minerals undergo changes in their composition.
300
What is GRANITE?
An engraving on this type of rock (used in your lab) would last longer than marble.
300
What is RILL EROSION?
This develops when running water cuts small channels into the side of a slope.
300
What is GRAVITY?
This force plays a huge role in pulling materials downslope.
300
What is WIND?
This erosional agent was most likely responsible for the appearance of the Arches National Park in Utah.
400
What is FROST WEDGING?
This is a mechanical weathering process that occurs when water repeatedly freezes and thaws in the cracks of rocks, often resulting in rocks splitting.
400
What are FOSSILS?
This does not contribute to the rate of weathering. (CHOICES: rock type, rock composition, climate, fossils)
400
What is GULLY EROSION?
This is erosion that occurs when a rill channel widens and deepens.
400
What is WAVE ACTION?
This type of erosion can move sand along a shoreline.
400
What are FREEZING and THAWING?
Frost wedging primarily relies on these processes.
500
What is EXFOLIATION?
This is a mechanical weathering process in which outer rock layers are stripped away, often resulting in dome-shaped formations.
500
What are COLDER, DRIER CLIMATES WITH LESS VEGETATION?
These parts of the world experience less chemical weathering.
500
What is WATER?
Gully and rill erosion are caused by this.
500
What are WINDBREAKS or WIND BARRIERS?
This are used in farming to reduce the effects of wind erosion.
500
What is HARDNESS?
This is a mineral characteristic that affects the rate of weathering.
