Research and write about at least three reasons as to how a fertile land can turn into a desert and at least two suggestions on how to prevent this from happening.

The major reason for this is desertification

Explanation:

Three major reasons on how a fertile land can turn to a desert;

1) Climatic changes; One of the ways desert changes into dry land is as regards climatic changes. Due to the eaten up of too ozone layer by the sun, we begin to experience changes in the texture of the soul as the climate affects the strength of the soil thereby making the area dry gradually.

2) Human activities; another reason for this is human activities. Some persons want to experience or experiment so they build up systems to this. Another as regards this is the activities carried out on the soil by humans.

3) Overpopulation; this still related to human activities is one of the reasons we experience desertification.

How to prevent it

1) Human limiting exploitation of the soil

2) More attention should be paid to taking care of the fertile ground against climatic conditions.

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals
