Why does the greatest erosion and transportation of sediment by a stream occur during a flood?
As flood waters rise, the slope of the stream as it flows to it's base level increases
Water erosion begins when runoff from rainfall flows in a thin layer over the land in a kind of erosion called?
Sheet erosion
Deltas are build up by?
sediment depposited where a river flows into an ocean or lake
What forces cause erosion and deposition?
Primarily a combination of Gravity, solar energy in the form of wind or waves, and tectonic forces Erosion is the movement of sediment and deposition is when that sediment gets placed somewhere else. Water falls to the Earth in the water cycle, and gravity pulls the water (or ice) down hill, carrying sediment with it (erosion). As the speed of the water slows as the slope decreases, the larger and larger pieces of sediment are settled out of the water by the force of gravity, becoming deposited someplace else. If there is no water present, sediment can be transported by any other fluid as well, usually air in the form of wind. As the wind slows, gravity is again the main factor in deposition. Tectonic forces also cause events such as lava flows, mass wasting etc.
What is load and how does it affect erosion?
Stream Load is the amount of material a stream can hold as it flows. As a stream flows it causes erosion, and this erosion is carried about as material in the stream. As too much is eroded, the extra material will fall to the bottom, or push it's way to the sides.
What is the definition of gulley erosion?
Gulley erosion is a process in which water flows down a small, narrow channel, transporting sediment to lower ground.
How does water change mountains?
Erosion. As the water flows down a mountain, the mountain erodes, or wears away =O)
What landform is created when weathered material is dropped as sediment when a river flows from a mountain to a plain?
alluvial fans
Explain the difference between erosion and deposition?
Glacial erosion is the process by which a glacial flows over the land, picking up rocks. Glacial deposition is the process by which a glacier gathers a huge amount of rock and soil as it Erodes the land in the path
Why does a river turn orange that flows from the mountain?
Impurities in the rocks and erosion usually add a color to the water
Why does the greatest erosion and transportation of sediment by a stream occur during a flood?
As flood waters rise, the slope of the stream as it flows to it's base level increases
How is the water cycle involved in moving rock and sediment from a mountain top to a beach?
When it rains on a mountain top, it creates a river. That river flows down carrying sediments witch end up in the beach.
The ease with which water flows through the open spaces in a rock or sediment indicates the of the rock or sediment?
permeability
What is the phase of water when it moves and flows?
erosion
Is formed when sediment is deposited where a river flows into an ocean?
A "Delta".
What sediment deposited where a river flows into a ocean or lake?
A delta.
The ease with which water flows through the open spaces in a rock or sediment indicates the what of the rock or sediment?
The permeability.
