Question

why might dew form in the morning? (1 point)
the temperature fell overnight, and colder air can hold more water vapor.
the temperature rose overnight, and warmer air can hold more water vapor.
the temperature fell overnight, and colder air can hold less water vapor.
the temperature rose overnight, and warmer air can hold less water vapor.

Explanation:

The capacity of air to hold water vapor is temperature - dependent. Colder air can hold less water vapor. Overnight, the temperature often drops. When the air cools down to its dew - point temperature, the excess water vapor condenses into liquid water droplets, forming dew.

Answer:

The temperature fell overnight, and colder air can hold less water vapor.
