Answer:
Air molecules scatter blue light more efficiently than other colors.
Explanation:
The sunlight has many colors and each of them has a different wavelenght. The color blue has shorter wavelengths and higher frequencies than the other colors. So, as sunlight goes through the air, the blue part causes charged particles to oscillate faster than the red part does and it is scattered more efficiently than the other colors and that's the reason for the sky to be blue.

Answer:
Coriolis effect
Explanation:
The Coriolis effect is an apparent force, corresponding to the earth's surface, which makes deflection of any moving object (air masses) to the right in Northern Hemisphere and to the left in Southern Hemisphere because of the earth's rotation. The Coriolis effect is a primary cause of various large scale weather patterns e.g. Coriolis effect is responsible for cyclones and trade winds.
The weather effecting fast moving objects e.g planes, missiles,rockets is affected by the Coriolis effect. Coriolis effect determines the direction of winds. A plane that flies along a path (north-south) should not fly directly towards the target location but it should fly either a little right or left of it to get to the target location.
The Coriolis effect also have an impact on ocean patterns. The winds power the seas. There are very similar patterns of ocean and atmospheric circulation. The effect is that ocean flows in their basins in the Northern Hemisphere and counter clockwise in the Southern Hemisphere.
Explanation:
North Africa has three main geographic features: the Sahara desert in the south, the Atlas Mountains in the west, and the Nile River and delta in the east. The climate there is hot so there is also less water that's why..
Answer:
Aloft high pressure develops in cold air regions while low pressure develops in warm air regions
Explanation:
A thermally-driven circulation, or thermals are the movement of warm air that move to a higher level due to the buoyancy forces acting on them. That is due to the difference in densities between the warmed and cool air
Given that pressure = Density, <em>ρ</em> × Gravity, <em>g </em>× Height, <em>h</em>, we have that decrease in pressure (low pressure) is due to low density, therefore, the warm air having low pressure, moves upwards, due to their low density
Therefore, the best option is aloft, (as we move higher), high pressure develops in cold air regions while low pressure develops in warm air regions
