Weathering
In chemical weathering, these are formed.
What are new substances?
Erosion never _____________! Never.
What is stops?
Of sand, silt, or clay, this one drains the fastest.
What is sand?
Irregular hills or mounds of sediment that are deposited directly from glacial ice.
What are moraines?
Erosion by __________ is responsible for most of the landforms found on Earth's crust.
What is water?
Of these three processes, this one is NOT an example of mechanical weathering: salt wedging, oxidation, and abrasion.
What is oxidation?
Three main forces that cause erosion.
What are water, wind, and ice?
The difference between a soil profile and a soil horizon.
What is that soil horizons make up the soil profile?
The process that forms sand dunes.
What is sand and silt are dropped (deposited) by the wind?
The two main categories of weathering.
What are mechanical and chemical weathering?
The way that freezing (ice wedging) breaks apart rock.
What is that water gets in cracks, freezes, and expands to break apart rock?
The process that forms arches.
What is that wind erodes soft rock leaving the hard rock arch on the outside?
The process of topsoil formation in three distinct steps.
What is:
1. Decaying materials (humus) in the top layer decompose and move down.
2. Weathered rock move up to towards the surface.
3. The two mix together to form topsoil.
The way you can tell that a valley is formed by a glacier instead of a river.
What is that river valleys are v-shaped, while glacial valleys are u-shaped?
The way that lichen break down rocks.
What is they secrete acid which causes cracks, the cracks fill with water, the water freezes, which causes the rock to crack?
Three types of chemical weathering.
What are oxidation, hydrolysis, hydration, solution, and organisms?
The reason that some rocks are rough and some are smooth.
What is that rocks start out rough, but over a long time they are eroded down into smoother rocks?
Four major properties of soils.
What are color, composition, texture, and permeability?
Three types of gravity-caused mass wasting from section 9.3.
What are slump, creep, and talus?
Five features created by ocean waves and currents.
What are sea arches, sea stacks, sea cliffs, platforms, spits, barrier islands, sea caves, and beaches?
Five types of mechanical weathering.
What are abrasion, pressure, freezing, temperature, salt wedging, plants, and animals?
One way that trees slow down erosion and one way they speed up erosion.
What is slowing erosion down by holding things in place and speeding up erosion by breaking up rocks with their roots?
Five factors that control weathering and affect soil development.
What are climate, vegetation, time, topography, type of rock, and biotic activity (any five of these six)?
Five features formed by rivers.
What are valleys, floodplains, meanders, oxbow lakes, deltas, alluvial fans, bars, caves, channels, and estuaries, mouths, and confluences?
The three part process of breaking down rock, moving rock, and dropping rock.
What are weathering, erosion, and deposition?
