🔥 Difference Between Erosion and Deposition


Erosion is defined as the removal of soil, sediment, regolith, and rock fragments from the landscape. Most landscapes show obvious evidence of erosion. Erosion is responsible for the creation of hills and valleys.
Deposition is the “yin” to erosion’s “yang.” At some point, an agent of erosion drops part or all of its load of rocks and sediments. Such depositions occur, for example, when a river loses some of its carrying power, as when its gradient or discharge diminishes.

What Is the Difference Between Erosion and Deposition? | Sciencing Erosion and deposition


Sediment refers to the solid particles of rock, soil, minerals, and organic matter that are carried by water. Sediment is laid down in layers of flat sheets at the bottom of the water column when the water's speed slows down.
Deposition is the geological process in which sediments, soil and rocks are added to a landform or land mass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
Where erosion is the dominant process, the coastline is retreating landward, and where deposition is the dominant, the coastline is advancing seaward. Erosional Coasts In places where there is an abundance of wave energy or ocean currents and/or a lack of sediment available for deposition, erosion of the coast will be the dominant mechanism of.

Erosion is defined as the removal of soil, sediment, regolith, and rock fragments from the landscape. Most landscapes show obvious evidence of erosion. Erosion is responsible for the creation of hills and valleys.
Give students practice classifying examples of erosion and deposition with this worksheet. In this Earth science printable, students will also explain these processes and define erode and deposit.
Erosion DEFINE. After pieces of the earth are broken down through weathering, those pieces are moved through Erosion. It’s the process of moving things from one place to another. Deposition DEFINE. After pieces of the earth are carried by erosion they are deposited somewhere else. Deposition means to deposit things somewhere else. Liquid.

Erosion and depositioncasinobonus

Erosion is the transport of sediments.
Agents of erosion include flowing water, waves, wind, ice, or gravity.
Eroded material is eventually dropped somewhere else.
This is called deposition.
How Flowing Water Causes Erosion and Deposition Flowing water is a very important agent of erosion.
Flowing water can erode rocks and soil.
Water dissolves minerals from rocks and carries the ions.
This process happens really slowly.
But over millions of years, flowing water dissolves massive amounts of rock.
Moving water also picks up and carries particles of soil and rock.
The ability to erode is affected by the velocity, or speed, of the water.
The size of the eroded particles depends on the velocity of the water.
Eventually, the water deposits the materials.
As water slows, larger particles are deposited.
As the water slows even more, smaller particles are deposited.
The graph in Figure shows how water velocity and particle size influence erosion and deposition.
Flowing water erodes or deposits particles depending on how fast the water is moving and how big the particles are.
Water Speed and Erosion Faster-moving water has more energy.
Therefore, it can carry larger particles.
It can carry more particles.
What causes water to move faster?
The slope of the land over which the water flows is one factor.
The steeper the slope, the faster the water flows.
Another factor is the amount of water that's in the stream.
Streams with a lot of water flow faster than streams that are nearly dry.
Particle Size and Erosion The size of particles determines how they are carried by flowing water.
The salts are carried in solution.
They are mixed thoroughly with the water.
They are mixed throughout the water.
These particles are not dissolved in the water.
The particles move in little jumps near the stream bottom.
They are nudged along by water and other particles.
In this process, the particles roll or drag along the bottom of the water.
How Flowing Water Moves Particles.
How particles are moved by flowing water depends on their size.
Deposition by Water Flowing water slows down when it reaches flatter land or flows into a body of still water.
What do you think happens then?
The water starts dropping the particles it was carrying.
As the water slows, it drops the largest particles first.
The smallest particles settle out last.
All these types of flowing water can cause erosion and deposition.
Erosion by Runoff When a lot of rain falls in a short period of time, much of the water is unable to soak into the ground.
Instead, it runs over the land.
Gravity causes the water to flow from higher to lower ground.
As the runoff flows, it may pick up loose material on the surface, such as bits of soil and sand.
Runoff is likely to cause more erosion if the land is bare.
Plants help hold the soil in place.
The runoff water in Figure is brown because it eroded soil from a bare, sloping field.
Can you erosion and deposition evidence of erosion by runoff where you live?
What should you look for?
Runoff has eroded small channels through this bare field.
Much of the material eroded by runoff is carried into bodies of water, such as streams, rivers, ponds, lakes, or oceans.
Runoff is an important cause of erosion.
Erosion by Mountain Streams Streams often start in mountains, where the land is very steep.
You can see an example in Figure.
A mountain stream flows very quickly because of the steep slope.
This causes a lot of erosion and very little deposition.
The rapidly erosion and deposition water digs down into the stream bed and makes it deeper.
It carves a narrow, V-shaped channel.
This mountain stream races down a steep slope.
It mainly erodes the bottom of its channel.
It carries the eroded rock downstream.
How a Waterfall Forms Mountain streams may erode waterfalls.
As shown in Figure and at the link below, a waterfall forms where a stream flows from an area of harder to softer rock.
The water erodes the softer rock faster than the harder rock.
This causes the stream bed to drop down, like a step, creating a waterfall.
As erosion continues, think, mobilegames download authoritative waterfall gradually moves upstream.
Why does a waterfall keep moving upstream?
Erosion by Slow-Flowing Rivers Rivers flowing over gentle slopes erode the sides of their channels more than the bottom.
Large curves, called meanders, form because of erosion and deposition by the moving water.
You can see how this happens in Figure and at the link below.
Over time, the curves shift position.
As meanders erode from side to side, they create a floodplain.
This is a broad, flat area on both sides of a river.
Eventually, a meander may become cut off from the rest of the river.
This forms an oxbow lake, like the one in Figure.
Deposition by Streams and Rivers When a stream or river slows down, it starts dropping its sediments.
Larger sediments are dropped in steep areas, but smaller sediments can still be carried.
Smaller sediments are dropped as the slope becomes less steep.
Alluvial Fans In arid regions, a mountain stream may flow onto flatter land.
The stream comes to a stop rapidly.
The deposits form an alluvial fan, like the one in Figure.
An alluvial click to see more in Death Valley, California leftNile River Delta in Egypt right.
Deltas Deposition also occurs when a stream or river empties into a large body of still water.
In this case, a delta forms.
A delta is shaped like a triangle.
It spreads out into the body of water.
An example is shown in Figure.
Deposition by Flood Waters A flood occurs when the game code river overflows it banks.
This might happen because of heavy rains.
Floodplains As the water spreads out over the land, it slows down and drops its sediment.
If a river floods often, the floodplain develops a thick layer of rich soil because of all the deposits.
For example, the Nile River in Egypt provides both water and thick sediments for raising crops in the middle of a the game code desert.
Natural Levees A flooding river often forms natural levees along the game code banks.
You can see how levees form in Figure.
This diagram shows how a river builds natural levees along its banks.
Erosion and Deposition by Groundwater Some water soaks into the ground.
It travels down through tiny holes in soil.
It seeps through cracks in rock.
The water moves slowly, pulled deeper and deeper by gravity.
Underground water can also erode and deposit material.
Caves As groundwater moves through rock, it dissolves minerals.
Some rocks dissolve more easily than others.
Over time, the water may dissolve large underground holes, or caves.
Groundwater drips from the ceiling to the floor of a cave.
This water is rich in dissolved minerals.
When the minerals come out of solution, they are deposited.
They build up on the ceiling of the cave to create formations called stalactites.
A stalactite is a pointed, icicle-like mineral deposit that forms on the ceiling of a cave.
They drip to the floor of the cave and harden to form stalagmites.
A stalagmite is a more rounded mineral deposit that forms on the floor of a cave Figure.
Both types of formations grow in size as water keeps dripping and more minerals are deposited.
This cave has both stalactites and stalagmites.
Sinkholes As erosion by groundwater continues, the ceiling of a cave may collapse.
The rock and soil above it sink into the ground.
This forms a sinkhole on the surface.
You can see an example of a sinkhole in Figure.
Some sinkholes are big enough to swallow vehicles and buildings.
When water slows down, it starts depositing sediment, starting with the largest particles first.
It picks up sediment and carries most of it to bodies of water.
Mountain streams erode narrow, V-shaped valleys and waterfalls.
Floodwaters may deposit natural levees.
Stalactites and stalagmites are mineral deposits that build up in caves as water continues to drip.
