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