What three factors control weather patterns on Earth?

What three factors control weather patterns on Earth? And what do they do to the weather specificly?





Thank you for your help!What three factors control weather patterns on Earth?

Most weather occurs in the lowest portion of the atmosphere, called the troposphere. The troposphere extends from Earth's surface up to an altitude of about 6 to 12 miles (10 to 19 kilometers). Three key factors that determine the weather in the troposphere are air temperature, air pressure, and humidity.What three factors control weather patterns on Earth?
Inclination of sun's rays,moisture content in the atmosphere and prevailing winds.
There are more than three, so if this is a homework question you need to look at your notes and see what your teacher thinks are important. It it were up to me, I'd say:





1. Distance from the sun


2. Rotation speed of the earth on its axis.


3. Distribution of land and ocean on earth.
So many possibilities. In addition to the above, weather is also influenced by the amount of solar radiation absorbed and heat emitted, type of ground cover, be it water, bare land, ice/snow, dense vegetation. All these create an energy imbalance, and what we call weather (wind, clouds, storms, etc) is simply the processes used by the atmosphere to restore balance.
