a. it only affects weather but not climate
b. it has no role
c. it influences weather and climate

Explanation:

• Humidity is a measure related to moisture in the air. Water vapor is the gaseous form of water. So, humidity measures the amount of water vapor in the air.
• The atmosphere is a key component in weather and climate systems. It is involved in processes like heat transfer, precipitation formation etc., so it influences both weather (short - term atmospheric conditions) and climate (long - term average of weather conditions).

Answer:

1. C. The amount of water vapor in the air
2. C. It influences weather and climate
