Weather refers to the current atmospheric conditions including air pressure, wind, temperature and moisture. The sun provides energy that evaporates water, causing weather phenomena like snow, rain, hurricanes and hail. Atmospheric pressure is measured in hectopascals at sea level using precise instruments, and air moves from high to low pressure areas causing wind. Temperature reflects the energy of atmospheric particle motion, and moisture makes things slightly wet or damp.

- 2. Weather refers to the state of the atmosphere at a specific time and place. Weather describes conditions such as air pressure, wind, temperature, and the amount of moisture in the air. The sun provides the earth with almost all the energy, which evaporates into water. For example: snow, rain, hurricanes, tornadoes and hail.
- 3. Is the atmospheric pressure at mean sea-level in hectopascals (millibars). Method of Measurement: Usually measured with a precision.
- 4. Air moving in a specific direction Results because air moves from regions of high pressure to low pressure.
- 5. Property of matter which reflects the quantity of energy of motion of the component particles. There are several scales used to measure this value.
- 6. Water or other liquid causing a slight wetness or dampness.
