True or false erosion is the transportation of weathered pieces of bedrock through the agents of wind water and gravity?
True
What characteristics of sedimentation and erosion lead to streams?
meandering
Age related erosion of articular carilages and formation of painful bony spurs are characteristics of gouty arthritis?
They are more likely to be associated with osteoarthritis.
How does erosion increase?
Erosion increases when there is a flood and when land is plowed and there is no cover crop that would prevent wind erosion.
What are three different types of erosion?
The four types or mechanisms of erosion are rill erosion, gully erosion, stream bank erosion, and sheet erosion. In sheet erosion a thin layer of the surface is removed. In rill erosion, small rivulets of running water gather together and cut small channels. In gully erosion, rills enlarge to form bigger channels too large to be removed by normal tillage. Finally, streambank erosion is the washing away of soil from banks of streams and rivers. Erosion is a natural, continuous process, but agricultural practices can speed erosion, resulting in lost soil, lost soil fertility, air pollution, and water pollution. Wind and water are the main agents that move soil.
What physical characteristics of bedrock are the characteristics responsible for the oldest rock remaining at the highest elevation?
What physical characteristics of the bedrock are responsible for the oldest rock remaining at the highest elevation
Why is bedrock called the parent material of soil?
Bedrock is called the parent material of soil because it is the underlying layer from which soil is formed through weathering and erosion processes over time. The composition and properties of bedrock influence the characteristics of the soil that develops on top of it.
How long does it take water erosion to erode bedrock?
Wind erosion is an ongoing process.
The glacial scouring by bedrock embedded in ice is erosion by?
The glacial scouring by bedrock embedded in ice is erosion by abrasion. This process occurs as the moving ice carries and grinds rocks against the underlying bedrock, wearing it down over time.
How does the process of plucking cause erosion?
Plucking is a glacial erosion process where ice plucks rock fragments from the bedrock as the glacier moves. This occurs when the ice freezes around rock fragments and then plucks them off the bedrock. The process of plucking can deepen existing cracks in the bedrock, leading to further erosion as the glacier moves.
What physical characteristics of the bedrock are responsible for the oldest rock remaining at the highest elevation?
The oldest rock at the highest elevation is typically due to its resistance to erosion compared to surrounding rocks. This may be because the rock is more resistant to weathering and erosion processes or because it is harder and more durable compared to other rocks in the area. These physical characteristics allow the oldest rock to remain at higher elevations over long periods of time.
What landscape feature is most likely to be formed from a bedrock layer that is resistant to erosion?
A ridge or a cliff would be most likely to form from a bedrock layer that is resistant to erosion. These features are created when surrounding softer rock is worn away, leaving the harder bedrock exposed.
The grinding action of debris present in running water breaking up the bedrock?
Erosion
Is sand on top of bedrock?
It is possible for sand to be on top of bedrock, as sand can be deposited on top of bedrock through natural processes like erosion, sedimentation, or glaciation. The presence of sand on bedrock depends on the geological history and the natural processes that have occurred in that particular location.
Does bedrock begin the formation of the soil?
Bedrock is the solid rock beneath the soil. Soil is formed as a result of weathering and erosion of the bedrock over time. So, while bedrock does not directly start the formation of soil, it does provide the material from which soil is developed.
Soil that has been moved away from its parent bedrock is called?
Soil that has been moved away from its parent bedrock is called transported soil. This can happen through processes like erosion, weathering, or human activities like construction or agriculture. Transported soil can differ in composition and characteristics from in situ soil.
Is increased erosion the cause of bedrock being left with scrapes and grooves?
Yes, increased erosion can cause bedrock to be left with scrapes and grooves. This process, known as abrasion, occurs when sediment particles carried by water, ice, or wind rub against the bedrock, wearing it down and leaving behind surface features like scrapes and grooves.
