CAUSES: weather processes are all the result of the atmosphere responding to uneven heating or cooling of the Earth

CONSEQUENCES: the weather includes different elements that influence it and each one has a different impact (consequence) on the Earth:
• rainfall —> flooding
• wind —> storm
• sunshine —> global heating, sunstrokes
• clouds —> non-growth of the plants, more precipitation
