18 Questions
What are bedrock channels?
Bedrock channels are paths that are eroded and cut through solid rock.
How do bedrock channels differ from alluvium?
Bedrock channels are formed by erosion of solid rock, while alluvium is the loose material deposited by water.
What are the two processes that can form bedrock channels?
The two processes that can form bedrock channels are running water and ice.
What happens to the energy of running water when it hits something?
The energy of running water gets transformed into work, such as erosion.
What is stream power?
Stream power is the rate of energy loss on a channel bed that can lead to erosion.
What do bedrock channels cut through?
Bedrock channels cut through the foundations of solid rock.
What can happen to a gently flowing river after constant rain?
A gently flowing river can turn into a fast-moving flood.
What can large chunks of frozen water do in a flood?
Large chunks of frozen water can create havoc as they flow downstream.
How can water cut channels through hard structures?
Water can cut channels through hard structures like earth and rock by exerting stream power.
What is bedrock?
Bedrock can be defined as a firm foundation of solid rock.
What is alluvium?
Alluvium is loose soil and sediments that usually cover bedrock.
How are bedrock channels formed?
Bedrock channels are formed through erosion and cutting of solid rock.
What is abrasion?
Abrasion is the erosion that occurs when particles scrape against each other.
How does abrasion contribute to the formation of bedrock channels?
Abrasion causes sediment particles to tumble and scrape against the bedrock walls, leading to erosion.
What is plucking?
Plucking is a process that involves the erosion and transport of large chunks of rock.
What causes plucking to occur?
Plucking occurs when moving glaciers melt and seep into cracks and joints of the bedrock, weakening it.
How do frozen chunks of rock and sediment contribute to erosion?
Frozen chunks of rock and sediment scraped along the landscape by glaciers perpetuate abrasive erosion.
What is stream power?
Stream power refers to the rate of energy loss on a channel bed that can lead to erosion.
