The sun is mostly composed of the elements hydrogen (H) and helium (He). By mass the composition of the sun is 75 percent hydrogen and 25 percent helium. Various metals make up less than 0.1 percent of the mass of the sun. The temperature of the sun’s surface is about 10,340 degrees Fahrenheit (5,726 degrees Celsius).
The Berg winds are winds that are forming in the plateaus deeper into the mainland. These winds move from the plateaus downwards towards the lowlands on the eastern coast of South Africa. The Berg winds are hot and dry winds and as they move they become even hooter because of the abiotic factors in the area.
These winds are very dangerous for the farming communities because they bring in very hot and dry weather with them. They dry out the soil and suck out every drop of moist out of it, and that combined with the hot weather they bring in is often devastating for the crops as they manage to destroy them, thus making a lot of damage for the farming communities that depend for their survival on those crops.
Heat fusion, i think. i dont really get question
The sahara made migrating rough because it was a desert but it was easier to pass through rather than south afria going through jungles
