Some basics about temperatures, pressures, winds, and seasons.

Temperatures, pressures, and gases

Remember these basic points you will likely have learned in your geography class:

  1. Air in motion is called wind.
  2. Warm air rises (causing a low pressure) and cool air descends (causing a high pressure).
  3. Earth’s rotation and gravitational force affect the way winds move.
  4. Wind directions are given based on where the winds blow from relative to where we are, not the direction in which they are going.

Here are three videos you can watch to learn about the interplay among temperatures, pressures, and gases.

Don’t give your full name; just give your initials (even this is optional).

  1. Why does air move? That is to say, why are there winds?
  2. Suppose the temperature of Earth were uniform everywhere at all times, what would be some of the impacts on living beings?
  3. What is the word met short for? What does the full word mean?
    • If you study and become an expert in the field that the full word means, what types of careers might you be able to have?
  4. Which climate controls were you able to make out in the three videos? Which ones were not there?
