Answer 1

The volume of water vapor in the troposphere ranges from 0.3% - 4% because water vapor moves between Earth and the troposphere during the water cycle. All weather happens in the troposphere due to its proximity to Earth's surface and the presence of water vapor.

Step-by-step explanation:

The statement that best explains why the volume of water vapor in the troposphere ranges from 0.3% - 4% is D) Water vapor moves between Earth and the troposphere during the water cycle. When water is heated, it evaporates and forms water vapor, which then moves into the troposphere through the water cycle. This process involves the evaporation of water from the Earth's surface and bodies of water, the transport of water vapor through the atmosphere, and the condensation of water vapor into clouds and precipitation.

The two best reasons why all weather happens in the troposphere are:

1. The troposphere is the atmospheric level closest to Earth's surface. This proximity allows for direct contact with the Earth's surface, which influences weather patterns.
2. The troposphere contains the most water vapor. Water vapor is a crucial component for the formation of clouds and precipitation, which are essential for weather events.

In summary, the volume of water vapor in the troposphere ranges from 0.3% - 4% because water vapor moves between Earth and the troposphere during the water cycle. All weather happens in the troposphere because it is the atmospheric level closest to Earth's surface and contains the most water vapor.
