What does a stream's ability to erode mainly depend on?
The amount of water in the stream and the gradient. However if you had two streams both with the same amount of water in them but with one stream flowing down a steeper slope (gradient) than the other, then the steep one has more ability to erode.
What are three things that cause erosion and deposition?
Below are the four agents of erosion, so take what you need:Fluvial erosion - rivers mainly. Rivers erode by hydraulic action, abrasion, attrition and solution. Deposition occurs because the river has run out of energy, or energy is low.Marine erosion - oceans and seas. These erode by hydraulic action and abrasion mainly, as the ocean has great sheer force. They do not transport much material, as most of the work is done by gravity, so most material is left directly under where it came from, but separate nonetheless.Glacial erosion - glaciers. Glaciers erode by plucking and abrasion, then deposit the moraine (glacial load) at the snoutAeolian erosion - wind. Wind erodes mainly by blasting sediment at rocks, which is classic abrasion. Sediment is often deposited as a dune.All agents of erosion cause both erosion and deposition as ultimately all eroded material is deposited.
Can waves or wind erode and deposit larger particles?
Yes, both waves and wind can erode and deposit larger particles such as sand, gravel, and even boulders. This process of erosion and deposition occurs when strong wave action or wind currents pick up and transport sediment, gradually wearing down and carrying larger particles to different locations.
What two types of water cause erosion and deposition?
Liquid and ice. Ice causes mechanical wedging that breaks up larger rocks until they are small enough to be removed from the source area by rushing water and deposited in a lower-energy environment.
In order for rejuvenation to take place in a stream what must occur first?
Rejuvenation in a stream involves the deepening of the stream channel by erosion of the stream bed. This erosion can occur due to changes in tectonic uplift, climate, or land use that increase the stream's energy and ability to erode its bed and banks.
Are tributaries erosion or deposition?
Tributaries can both erode and deposit sediment. In the upper reaches of a tributary, erosion may occur as the flowing water picks up and moves sediment. Closer to the main river, deposition may happen as the velocity of the water slows down and sediment is dropped.
What is the verb for deposit?
Deposit is both a noun and a verb. She made a deposit at the bank. (noun) She was able to deposit the money at the bank. (verb)
What is alluvial terrace or bar upland?
An alluvial terrace is a flat area next to a river or stream that is built up by sediments deposited during flood events. Alluvial bars are more elevated and formed by coarse sediments like sand and gravel. They are both important for flood control and providing habitat for plants and animals.
Till and outwash are both deposits of sediments from what?
Glaciers
Why is surface water both a creator and a destroyer of sediments and sedimentary rocks?
Water chemically and mechanically weathers sedimentary rocks. It also weathers and erodes all rock types, transporting and depositing the sediments, a step in the formation of sedimentary rock.
What do floods do to the land?
Floods can bring both benefits and challenges to the land. They can deposit nutrient-rich sediment, which can make the soil more fertile for agriculture. However, floods can also erode soil, damage crops, disrupt ecosystems, and lead to loss of property and life.
How do floods cause weathering or erosion?
Floods cause weathering by carrying sediments and debris that can physically break down rocks and soil. They also cause erosion by transporting these sediments downstream, wearing away the land and changing the landscape over time. Floodwaters can both pick up and deposit sediments, which can lead to both weathering and erosion processes occurring along the flood's path.
