High and low pressure system both bring changes in weather.
Answer: Option D
Step-by-step explanation:
There are certain areas which are affected by high pressure of air and some are affected by low pressure of air. This high and low pressure of air is caused by the ascending and descending of air.
But both affect the weather and causes a change in it. Due to the high pressure of air, weather becomes cold and dry and on the opposite side, because of low pressure of air, there is formation of clouds and rain.
