Question

What happens when a low air pressure system meets a high air pressure system?

1. The temperature of the air drops to below freezing.
2. The air moves to the low pressure system, creating wind.
3.The precipitation is removed from the air.
4. The air starts blowing in an easterly direction.

Answer 1

2nd number is right because when A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet.

Answer 2

Answer:

The correct option is 2) The air moves to low pressure system, creating wind.

Explanation:

• Air with higher temperature have lower pressure while cold air is more dense and has higer pressure.
• The Sun's ray heat up the air near the Earth's surface in a differential manner creating high pressure and low pressure systems.
• When these two systems interact with each other, the air which is actually formed of gases, move from higher pressure towards the lower pressure.
• This movement of air gives rise to wind on Earth's surface.
