In physical geography<span>, a </span>dune<span> is a </span>hill<span> of loose </span>sand<span> built by </span>wind<span> or the flow of water.</span><span> Dunes occur in different shapes and sizes, formed by interaction with the flow of air or water. Most kinds of dunes are longer on the windward side where the sand is pushed up the dune and have a shorter "slip face" in the lee of the wind. The valley or trough between dunes is called a </span>slack<span>. A "dune field" is an area covered by extensive sand dunes. Dunes occur, for example, in some </span>deserts<span> and along some coasts.</span>
Sand dunes are formed by the wind, it is formed usually along the beach or desert. It is formed when the air continues to blow sand into an area behind an object. It continues to grow as grains of sand get condensed. The sand can be transported to a different location by saltation, surface creeps and by suspension where it can settle along with beach and desert in order to form dunes.
when plants absorb more energy than they use it can damage critical protein. to prevent this plants turn the excess energy into heat and send it back out.
it might make it crack and harden it will also make it chucky instead of soft grassy fertal soil it will have almost no vitimin for plants to grow or to stay healthly
