What happens when a winds hits a barrier like a mountain?

It moves downwards with the same strength.
• It increases its intensity.
• It is pushed upwards and spreads out.
• It breaks apart and moves in all directions.

When a wind hits a barrier like a mountain, it is pushed upwards and spreads out. As the wind collides with the mountain, it is forced to rise, causing it to cool and condense, potentially leading to the formation of clouds and precipitation. This process is known as orographic lifting and can result in increased rainfall on the windward side of the mountain and drier conditions on the leeward side.
