What are two actions that would cause an increase in relative humidity

Answers

relative humidity increases when the amount of moisture air can hold increases.The increase can be caused by the introduction of more moist air OR a temperature drop of the air/moisture mixture without a loss of moisture. Colder air will hold less moisture than warm air;as the temperature goes down the amount of moisture relative to what the air can hold increases

Answer:

cooler air

From which layer of the atmosphere do particles of air escape into space?

will give brainly

Answers

Answer: The layer from where particles of air escape into space is exosphere.

Explanation:

The atmosphere is divided into layers. There are 5 main layers of atmosphere, which are: Troposphere, Stratosphere, Mesosphere, Thermosphere and Exosphere.

  1. Troposphere is the lowest layer of the atmosphere where most of the weather occurs.
  2. Then comes the Stratosphere which is about 50 km above the Earth's surface. It contains most of the ozone which is present in the atmosphere.
  3. Then comes the Mesosphere which starts from 50 km and extends upto 85 km from the Earth's surface.
  4. Then comes the Thermosphere which starts from 90 km and extends to between 500 km and 1,000 km.
  5. Exosphere is the last layer of the atmosphere, through which anything escapes the atmosphere to space. This layer extends upto 10,000 km from the Earth's surface.

Hence, the layer from where particles of air escape into space is exosphere.

Answer:

Exosphere
