b. compared waves deposit sand on the shoreline

c. constructive waves are the major contributor to beach erosion

Loess grows, or forms up, at the margins of deserts. For example, When the wind blows in Gobi desert situated in Asia, it pulls up and takes fine particles. The particles have sand crystals made of mica or quartz. It can have organic material too like dusty remains of skeletons if animals.

On the far away of the desert, mist in the air makes the jots and dirt to fall on the ground. Then the roots of grass or other plants trap the dust and keep it to the ground. More dusty will be slowly swollen and losses are formed this way.

C. sand grains move up the slope and accumulate on the downwind face

Sand dunes are complicated sensations and the emergence of a sand dune depends on an immense number of various circumstances, like the mass/configuration of the sediment, blow rate, mist levels, and roots levels.

The sand dunes move over the ground in a blow. The fragments are driven up the windward view of a dune till they approach the top and then they fall down the side apart from the wind. Other grains are swelled up and over, overcoming the initial. This remained movement leads the dune over the land.

Abrasive blasting is usually known as sandblasting. It is the procedure of compulsorily driving a brook of rough material opposite an exterior under huge pressure to polish a rude surface, roughen a soft surface, mold a surface or lift surface contaminants. A pressurized liquid normally pressed air or a diverging wheel is practiced to drive the blasting stuff called media.

B. Eolian systems are shaped by the wind

The word originated from the name of the Greek god Aeolus, the guardian of the blowing winds.

Eolian systems concern to wind motion. It is a wind activity to shape the earth. Winds may consume, bliss, and coat stuff and are capable tools in areas with scattered nature, a deficiency of soil mist and a high number of unconnected sediments. eolian means are necessary for arid conditions so as deserts.

Marginal vegetation performs an essential task in sustaining the sincerity of dune systems. They work as a windbreak, catching inserted sand jots and preserving the dune system. Out of vegetation, this real shielding block would be missed to the impressions of wind and tide depletion.

Coastal plants have accommodated to exist in an atmosphere where they are shown to salt splash, sandblasts, strong winds, raised temperatures and flooding.

The fetch also called the fetch length. It is the length of water over which wind has gone through. Fetch is practiced in geology and cinematography and its outcomes are normally linked with sea environment and when it touches shore it is the principal part that generates wind wave which drives to marginal erosion and flooding. It also performs a big role in the long-shore direction as well.

Coastal erosion is generally described as the damage or displacement of land accompanying the coastline due to the motion of waves, courses, streams, wind-driven water, waterborne ice, or additional consequences of storms

Corrosion is a normal method, which switches a processed ore to a further stable form of chemicals, as its oxide, hydroxide, or sulfide. It is the gradual dissolution of stuff ordinarily ores by the chemical or battery powered chemical response with their surroundings. Corrosion engineering is the profession committed to dominating and preventing corrosion.

Corrosion discredits the beneficial characteristics of substances and compositions including durability, look, and permeability to fluids and gasoline.

True

Weathering is the practice of fading and cracking up rocks. It is the physical and chemical division of rocks and crystals at or near the earth's exterior.

Biological Weathering

It is the influence of living things, like the tubers of a tree spread into the territory they can pries stones individually. It also happens on an extremely tinier order through non-mobile organisms and moss.

In the latest degree of karst many of the real limestone completely dissolves away. All that rests are a some distributed holds and tiny hunks of limestone moved to punch through the exterior. From the cover, the scene may not carry any

notable symptoms of what is proceeding on underneath the facade, besides for some sinkholes scattered.

C. Constructive waves are the major contributor to beach erosion

Constructive waves are weak strength surges that occur in the build-up of substance on the shoreline. Constructive waves are feeble but have powerful swashes than repercussions. This indicates that any element being taken by the sea is washed up and starts to build up with the coastline. The stuff that is dropped by constructive surges can several oftentimes be viewed by the formulation of shores.

Cherish is an overly-romantic word for something that inspires a career or hobby.  Geographers cherish the Earth like mathematicians cherish numbers.  It's more like an intense interest rather than a romance.
