Weathering
Takes place when a body of rock is exposed to the weather.
What is Weathering? pg. 435
The mechanical process, usually driven by water, gravity, wind, or ice that removes sediment from weathering.
What is Erosion? pg. 465
All of Earth's water?
What is the Hydrosphere?
This happens when rocks are stressed, the resulting strain can be elastic, ductile, or brittle.
What is Deformation? pg. 479
Is composed of two atoms of hydrogen and one atom of oxygen bonded together.
What is Water? pg. 490
The mechanical breakdown of rock into smaller fragments.
What is Mechanical Weathering? pg. 435
Particles moved by the wind.
What is Abrasion? pg. 469
What is Lithosphere, Hydrosphere, Biosphere, and Atmosphere?
A measure of how readily a rock will respond to stress.
What is Rock Strength? pg. 481
Stored in the open spaces within rocks and within unconsolidated sediments.
What is Groundwater? pg. 510
The process by which water seeps into cracks in a rock, expands on freezing, and thus enlarges the cracks.
What is Frost Wedging or Ice Wedging? pg. 437
Happens when fragments or rock break off relatively easily from steep bedrock slopes.
What is a rock fall? pg. 460
The rigid rocky outer layer of the Earth.
What is the Lithosphere?
A symmetrical to semi-symmetrical upwarping of rock beds, like in Utah’s San Rafael Swell.
What is a Dome? pg. 486
Can be rain, sleet, hail, or snow. Sometimes it falls back into the ocean, and sometimes it falls onto the land surface.
What is Precipitation? pg. 493
The two main processes that weathering include.
What is Mechanical and Chemical Weathering? pg. 435
What landform has different compositions depending on their location, and are usually quartz because, in humid areas, other minerals weather into clays.
What are Sand Dunes? pg. 470
The parts of land, sea, and atmosphere in which organisms are able to live.
What is Biosphere?
Small bodies of freshwater that usually have no outlet; often are fed by underground springs.
What are Ponds? pg. 503
The process in which a solid changes directly into a gas without first becoming a liquid.
What is Sublimation? pg. 493
The failure and downslope movement of rock or unconsolidated materials in response to gravity.
What is Mass Wasting? pg. 460
Stones that have become polished and faceted due to abrasion by sand particles.
What are Ventifacts? pg. 469
The mixture of gases surrounding the Earth, held in place by gravity.
What is the Atmosphere?
The percentage of open space within unconsolidated sediment or rock.
What is Porosity? pg. 511
The study of bodies of freshwater and the organisms that live there.
What is Limnology? pg. 503
