How is weathering related to erosion?

Question

I am reviewing for my science final next week and I can't find the sheet I did it on. Remember, best answer gets 10 points!

Answer 1

EROSION
soil erosion is almost always as a result of human intervention.
the trees are cut down and these trees existed to provide a cover against the rays of the sun which now dries out the soil ,and the wind can than easily blow away the dust that is formed ,------this is wind erosian

because the trees are no longer there, whose roots bound the soil together ,and because their canapies of foilidge no longer exist the rain now has easy acces to the unprotected ,now dry surface and the rain waters wash away the top soils ,------this is water erosian

farmers plow large plots of land to plant maize or wheat or what ever and as happened in the 20s in the USA,they plowed in straight lines.when the winds came they blew along the straight lines and picking up speed removed millions of tons of top soil(wind erosian) turning vast teritories into dessert deprived of arable soil

today the farmers plow in circles and curves to prevent this building up of speed by the wind,

but still vast sections of land are exposed to the sun which kills the micro biotic life ,that builds the black and rich top soil and tons of water is evaporated by the sun.,
WHEATHERING
under normal conditions with out the damage done by man that removes the earth surface protection ,weathering is a much slower type of erosion wind over many years can sandpaper shapes into rock wall with the dust that is carried by the wind,
or rainfall and the consequent flows of water of the rainfall it self of the resulting water flows over land can also carve the landscape.
but these are gradual processes ,that take many ,many years ,and in between returning plant growth again cover exposed ground and protect it

erosion as a result of mans actions can do in one night ,what takes nature hundreds of years
such as MUD SLIDES
in Mexico in the mountains the increasing
populations of indigenous peoples are cutting down trees to plant corn ,this land is productive for a few years before it becomes poor and useless for farming.
the roots of the trees that have been cut down rot and tunnels are created with their diaaperance ,with heavy rains these tunnels fill up with water and the soil lifts and moves down wards .

mudslides are caused and large parts of the mountains are exposed to the rock.

the mud destroys the lands beneath and the exposed areas NEVER recover leaving the area with out vegetation forever

to recover eroded soil is a lenthy process ,which involves planting, bushes ,grasses and trees under difficult conditions to hold the soil and to create bariers to stop further movements on the surface and trap any organic matter that ends up there.we can help by adding mulch(chopped organic matter and plant leafy plants to be chopped down for this purpose,.

Answer 2

Weathering: the physical and chemical processes that change the characteristics of rocks on the Earth's surface. In order for weathering to occur, the physicial environment of the rocks must change and the rocks must be exposed to air, water in some form (ice, snow, or liquid), or the acts of humans or other living things. Therefore, weathering is the response of rocks to the change in their environment.

There are many types of weathering processes. One type is called physical weathering, when rocks are broken down into smaller pieces without changing the chemical properties of the rock. The rock just becomes smaller, but it stays the same type of rock. The end products of weathering are called sediments, and are classified as boulders, cobbles, pebbles, sand, clay, etc.

Erosions refers to the transportation or rock, soil, and mineral particles from one location to another by the action of water, wind, or ice. The main power behind all the things that cause erosion is gravity. An example of erosion would be glaciers transporting rocks and even boulders down the slope of a mountain.

So, basically, weathering breaks down the rocks, and erosion refers to the transportation of the sediments to other places. Weathering breaks down the rocks into sediments, and as soon as the rock particles move, it is considered erosion.

Hope this helps out! Good luck with your science final next week. :)

Answer 3

Without looking at a dictionary or anything, this is what I would say.

Weathering is aging from exposure to the climate. This would include the sun, UV, rain, heat, cold, ice, wind, oxygen, ozone, and a whole bunch of other stuff.

Erosion is the wearing away of something. A river erodes its banks. The ocean erodes the shore.

Does that help?
