Answer:
space
Explanation:
As air gets warm, the air molecules have more energy and move around more, taking up more space. As the warm air expands, it becomes less dense than the cold air, so rises up and floats above the cold air.
Answer:
Yemen's principal natural resources are oil and natural gas as well as agriculturally productive land in the west. Other natural resources include fish and seafood, rock salt, marble, and major unexplored deposits of coal, gold, lead, nickel, and copper. The most common crops are cereals such as millet, corn (maize), wheat, barley, and sorghum; myriad vegetables from a burgeoning truck farm industry have appeared on the market in recent years.
Weathering is the breaking down of rocks, soil and minerals. Erosion is the process of being gradually worn away by natural agents such as wind and water.
Some rocks may be generally weaker which causes them to break down quicker than rocks that are stronger.
Answer:
cos 90° = 0, because the angles are complements
Explanation:
Complementary angles are those angles whose angles are sum up to 90 degrees that we called right angles
Just like
one angle is 45 degrees
And, the other angles are also 45 degrees
So, the sum of both two angles are 90 degrees
Now if
sin 0° = 0
The cos 0° = 0 as the angles are considered to be the complement
We used the equation as shown below:
