what happens when a wind hits a barrier like a mountain?
a. it moves downwards with the same strength
b. it breaks apart and move in all directions
c. it is pushed upwards and spreads out
d. it increases its intensity
When wind hits a barrier like a mountain, the most common scenario is that it is pushed upwards and spreads out. This is due to the phenomenon called orographic lifting. As the wind encounters the mountain, it is forced to rise. As the air rises, it undergoes adiabatic cooling, which causes the formation of clouds and precipitation on the windward side of the mountain. The wind then continues to flow over the mountain, but with reduced intensity on the leeward side. So, the correct answer is c. It is pushed upwards and spreads out.
