What causes deepening and widening of rill channels?
Rill erosion which is erosion by running water in small channels
How does erosion change earth's surface?
Erosion changes the surface by creating rivers, streams and valleys.
What are erosion and weather caused by?
erosion is caused by rain, rain is caused by the sun heating up the earth's water and creating the water cycle
How do hurricanes change landforms?
Hurricanes can causes significant coastal erosion from waves and storm surge. Heavy rain can cause flooding, which can cause great amounts of erosion around river channels.
Does soil erosion cause acid rain?
Kinda-sorta. All rains can cause soil erosion, as it doesn't take much for running water to cut channels and move loose dirt about.
What is meant by erosion in channels?
Gill Erosion
What causes deepening and widening of rill channels?
Rill erosion which is erosion by running water in small channels
Type of water erosion that forms larger channels down a steep slope?
The type of water erosion that forms larger channels down a steep slope is called gully erosion. Gully and rill erosion are the dominant types of water erosion in the world.
How does erosion change earth's surface?
Erosion changes the surface by creating rivers, streams and valleys.
What causes wide river channels?
by erosion eroding the banks and beds of a river
What role does water play in creating a sinkhole?
Weathring and erosion .
What is rill erosion?
This is the removal of soil by runoff from the land surface whereby numerous small channels, generally up to 30 cm deep are formed...................................................................................Or.......................... Rill Erosion: This is the flow of run off water causes concentrated channels,to be formed at the surface of the soil.
What helps reduce erosion by creating level areas for crops?
Mulching
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.
How does man impact the forces of erosion?
Human activity affects erosion in numerous ways. Humans strip away surface vegetation that protects against serious erosion, (such as deforesting hillsides to build houses which allows rain to directly hit the soil and erode the hillside sometimes catastrophically in mudslides where the forest had previously protected the hillside, or grasses in the prairie to build farms allowing wind to erode the soil away as happened during the Dust Bowl), or covers land with non-porous surfaces such as concrete and asphalt (which concentrates water through small channels, enabling heavy erosion). Human activity can also attempt to reduce erosion by creating erosion-control measures by purposefully planting in erosion-prone soil to help hold the soil, or creating small dams in streambeds to slow the water and reduce its ability to carry material way.
What are erosion and weather caused by?
erosion is caused by rain, rain is caused by the sun heating up the earth's water and creating the water cycle
How soil erosion might affect rock?
It breaks down rock, creating sediment
