Multiple Choice

What is the relationship between temperature and the maximum amount of water vapor that an air parcel can hold?

• The lower the temperature, the larger the amount of water vapor an air parcel can hold. They are positively related.

• The higher the temperature, the smaller the amount of water vapor an air parcel can hold. They are negatively related.

• The higher the temperature, the larger the amount of water vapor an air parcel can hold. They are positively related.

• The higher the temperature, the larger the amount of water vapor an air parcel can hold. They are negatively related.

3 Monsoon system

Monsoons are winds that change directions seasonally,
blowing from one direction in summer and from the
opposite direction in winter.

They develop due to seasonal variations in air pressure.

Winter monsoon is cold and dry
