Vegetation can be assumed to reduce overgrazing of grasslands if it is woody vegetation. Woody vegetation would act as a physical barrier to grazers. The roots of vegetation, including grassland, bind soil together, thereby preventing erosion.
Deforestation occurs in Haiti because of a lack of energy options in the country. Haitians cut down trees for burning or charcoal production.

An ore is a type of mineral or rock which has a high enough concentration of a desirable element such that it's economical to extract that desired element. This means that the actual concentration of metal in an ore varies quite dramatically depending upon the metal. For instance, Bauxite, which is the ore for aluminum contains approximately 15% to 25% aluminum. But for gold, it's not uncommon to profitably extract 1 ounce of gold from several tons of rock.</span>

Most smaller stars don't have a radiative zone. In the radiative zone, the material is hot and dense which enables thermal radiation transfers from the core outward though the Sun. This layer is size dependent therefore smaller stars might not have this zone at all.
The continental crust is located on the Earth's surface. Most continental crust is dry land above sea level. Some of it is beneath the pacific ocean.
