How does sand help the environment?

Different scenarios for different environments.  Sand is a habitat for many marine animals.\n\nIn the case of sand dunes along the coast- they are natural structures which protect the coastal environment by absorbing energy from wind, tide and wave action.

to maximize surface area for the collection of sunlight and minimize weight and material used. also, yes it helps transport water and nutrients.

It helps with the environment in many different ways such as increasing the annual rainfalls, keeping the environment cool, and decreases the ratio of wind evaporation which saves the atmosphere from becoming dry. This provides immunity to inhabitants of such areas from chest and respiratory diseases. The tree helps in stabilizing canal banks and preventing soil erosions

The very best way to help the environment is for each person to do what he or she can.  Organizations are interesting, but what really makes the difference is what you actually do.  Keep it simple.  Pick up a piece of paper.  Plant a flower.  Clean a sidewalk.  Keep your part of the world better and it makes the whole state and the whole world a little bit better.  When others notice what you are doing, they in turn can follow your good example.  That is what will do it.

We use the heavier sand, not the fine playsand, it's a little heavier(probably more rock in it). It seems to hold up better.

Several people on here are actually right. The first two are both right.\n\nThe first one had the most simplistic but straight forward answer.\n\nRocks are eroded and the sediments are carried away as runoff into rivers & other low lying places. Most of this sand is carried onto the coastal plains & into the ocean & deposited there.\n\nSince the desert has very little weathering by water it is usually done by wind through a process called abrasion. Sand grains brushing up against rocks wearing it away like sandpaper.\n\nHowever, like someone pointed out earlier, in earth's past life many times the ocean as regressed & transgressed bringing deposits of sand with it. It could have gotten there by that method but more than likely these deposits became sedimentary rock first & was then worn away later by wind.

It provides a cover for the animals and nutrients that reside there, so that in hot, dry weather, or rainy storms there is covering to keep things from seeping out.\nIt also provides a habitat for many creatures.

you can't get any sand from it. because height means distance above the sand. so for 1400ft depth only we can get sand man

This will create land & sea breezes.\n\nLand (sand) gains & loses heat faster than water due to water's latent heat properties.\n\nDuring the day, the land heats up faster than the water. A low pressure will develop over the land. This means that the air above the ground is warmed & will rise.\n\nSince air pressure will equalize, air from over the sea will move inland to replace the air that was lifted. A convection current starts. This is a sea breeze. (winds are named for the direction they come from.)\n\nThe opposite occurs at night. The land cools faster than the water. Since the water is warmer at night, a low pressure cell forms over the sea.\n\nHigher pressure from over land moves toward the low pressure to equalize. This is called a land breeze b/c it comes from the land.

Don't use sand! I believe that they use crushed up walnut shells in blasting on surfaces that you don't want to get all pitted up.

-A desert is similar because the dunes seem to look like waves.  There are high points and low points.  \n\n-Also, sand can become liquified in certain situations, though I'm not sure if that can help...\n\n-Sand covers just as a sea would.  It can blanket vast lands.\n\n-There is a point where you cannot see past a certain point while in a sea or in a desert.  Like when people say they are lost at sea and they cannot see land.  Same in a desert..only the land they are looking for is normal land.

Try sieving it - the sand will pass through the gravel will stay behind.

Wind is the primary force that creates sand dunes. Sand itself is generally created by the erosion of rock material by water and ice.\n\nThere are two types of movement that wind causes in sand. One is called saltation. Wind picks up grains of sand and gives them forward momentum, but they will often fall back and bounce repeatedly, or cause other grains to move. This is about 75% of all movement of sand to form dunes. \n\nThe other movement method is called surface creep. Surface creep is the process where heavier sand grains are moved forward along a surface as saltating grains strike them.  It is estimated that about 25% of sand movement is moved this way. \n\nAs this moving sand encounters obstacles or changes in elevation such as a basin, the irregular flow of the wind will cause sand to accumulate in the "wind shadows." However, obstacles are not necessary to make dunes. The bouncing sand grains will gradually slow, losing energy from impacting heavier grains, and the sand itself tends to slow the wind speed close to the ground. Together, this differential speed of motion among grains, and saltation drag on the wind, will begin to produce small piles of sand, or ripples. Larger grains will tend to accumulate because the wind cannot move them, and cause more ripple effects.\n\nTrue dunes are formed when relatively strong winds blow over fine grained sands. The coarser grains tend to stabilize the windward surface of the dune, and finer grains are moved by saltation upward and over the peak of the dune, where they fall out of the wind and slip downward. \n\nIn areas of active dunes the dunes will migrate in the direction of the wind over periods of years. Many of the largest sand dunes in the world are considered paleodunes that are no longer moving. \n\nTo read more about sand dunes and how they form, as well as some information on the different types of sand dunes go here:\nhttp://www.nps.gov/whsa/Sand%20Dune%20Geology.htm

The most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide), usually in the form of quartz which because of its chemical inertness and considerable hardness is quite resistant to weathering. However, the composition of sand varies according to local rock sources and conditions.

Abrasion by wind-driven sand.\nParticle removal by wind alone.\nDecomposition and weakening due to sunlight (especially the UV).\nCracking due to temperature changes.\nThis doesn't include biological damage which can be severe due to chemicals secreted by various growths such as lichen.

sand is small pieces of rock that has been eroded away from a larger stone.it would take years to get a few pounds of sand from a 25 pound rock but wind rain and snow will break down the rock to produce sand. soil is dirt formed from leaves and twigs from trees. all this will decay and produce soil along with rain and other dying vegetation.go into a densely wooded area and you will find soil.be sure its a hardwood forest.that means maples oaks and other varieties of trees but not conifers, conifers are of the pine family and fir all evergreens.the foilage dropped this fall will take about 2 1/2 to 3 years to decay enough to be soil which is the best for growing flowers and bulbs

Erosion breaks up igneous and metamorphic rocks, and the particles build up to create sedimentary rocks.  \n\nHope this is helpful.
