Landforms
A large, nearly level area of land this is higher than the surrounding area.
Plateau
A "horizon" can also be called a ________.
layer
Calcite, which dissolves in acid, is found in this layer of rock.
Limestone.
The breaking apart of rocks into smaller rocks.
Physical Weathering
To make an educated guess is to make an _________.
Inferrence
A large bend in a river
meander
The top layer of soil is called (two possible correct answers)
Humus, or Organic Material.
This process breaks apart different layers of rock at different speeds, depending on how hard or soft they are.
Differential erosion
The wearing down of rocks through wind, water or even human actions.
Erosion
Clay, sand, silt, and pebbles are examples of _____.
Sediments
Where clay is most likely to be found due to erosion (at the end of a river).
Delta
The layer just below the O horizon. Confusingly, it is technically not on the top.
Topsoil
Limestone fizzing when acid is put on it is an example of this process.
Chemical Weathering
Acid is usually the cause of __________ (such as in caves).
Chemical Weathering
How far above (or below) sea level
Elevation
A deep "cut" in a rock, usually formed from a river flowing through it.
Canyon
The layer just below the A horizon.
Subsoil (B)
A sedimintary rock made of silt or clay, typically pretty soft.
Shale
When a mass of rocks hit the ground from high up, like an avalanche.
Rock fall
Ice wedging is an example of ____________.
Physical Weathering
A point of very high elevation
Mountain
This layer is below parent material.
Bedrock
Scientists do this when they are matching layers of rock from different locations, such as the Grand Canyon at different mile markers.
correlation
Different layers eroding at different speeds is called __________
differential erosion
When geologists fine a relationship between rock laters from different locations, they are making a ___________. (correlation, hypothesis, rock column)
Correlation
