Answer:

solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and soil. As liquid water evaporates or transpires, it forms water vapor and clouds, where water droplets eventually gain enough mass to fall back to Earth as precipitation.

Which defines the average kinetic energy of a system's particles?

ch4aika [34]

<h2>Answer:Temperature</h2>

Explanation:

Average kinetic energy of a system of particles is given by $\frac{f}{2} kT$ .

where,

$f$ is the number of degrees of freedom of the particles.

$k$ is the boltzmann constant.

$T$ is the temperature.

For general gases,

$f=3$

For a given degrees of freedom,average kinetic energy is directly proportional to temperature.

So,the average kinetic energy depends on temperature.
