Areas of the earth with lots of direct sunlight have warm air. explain why warm air rises and leaves pockets of low pressure behind ?

Equator

Explanation:

The equator and the regions near the equator receive maximum solar radiation every year. These areas exhibit warm air. The warm air rises and the cools down then further at low pressure zone it might not be able to hold the water vapors. So the water vapors present in the air will cool down and condense in the form of clouds and the rain fall down.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
