Question

3: Where does most of the water in the atmosphere come from?

4: What determines the speed of movement of molecules?

Thank you for your help

Answer 1

4)

The temperature determines the speed the molecules move, higher temps move faster lower temps move slower, at 0*K molecules dont move atall, complete absense of heat

Answer 2

3. About 90% of the water in the atmosphere is produced by the evaporation of water. The other 10% comes from transpiration of plants.

4. Temperature is a measure of the speed of motion of the molecules. The higher the temperature, the faster the molecules move.

Answer 3

3. Most of the water in the amosphere comes from seawater being evaporated by the sun.

4. Temperature is basically kinetic energy in molecules. This energy affects the speed of the molecules.
