Answer:
Arithmetic Density
Explanation:
it is the total number of people divided by the total land area and this is just talking about population density not the amount of arable land (physiological density) or comparing the number of farmers to the area of arable land (agricultural density)
They begin as streams in mountains or hills
Best describes Antarctica are known as reserves of oil and coal as well as mineral deposits in Antarctica.
<h3>What do you mean by Antarctica?</h3>
Antarctica is known as reserves of oil and coal as well as mineral deposits Antarctica although detailed knowledge of these mineral deposits.
There are deposits of minerals in Antarctica including coal and iron ore. Antarctica refers to the major source of oil and coal for the world.
Therefore, C is the correct option.

Recommended rates of potash for grazed grass are 60kg/ha and 30kg/ha of K2O for soil index 0 and 1 respectively. For soils with higher soil fertility levels no potash required.
Very large quantities of potash are removed in grass silage which must be replaced to maintain soil fertility and yield potential. The following is guide to typical potash offtakes from multi-cut silage systems.Low soil magnesium levels will affect grass yield as well as mineral balance in the animal. Apply 50-100 kg/ha MgO every three to four years at Mg index 0. Yield response is less certain at index 1 but magnesium application is justified in terms of insurance for grass yield and mineral balance for the animal, to maintain a soil magnesium index of 2.
Where lime is required and Mg levels are 0 and 1, use magnesian limestone as the most cost effective magnesium source. Where pH is satisfactory, specific magnesium fertilisers (see table below) should be used for soil improvement. Use water soluble forms of magnesium where rapid plant uptake is required.
