What is weather?

• The weather is just the state of the atmosphere at any time, including things such as temperature, precipitation, air pressure and cloud cover.

• Daily changes in the weather are due to winds and storms.

• Seasonal changes are due to the Earth revolving around the sun.

What is climate?

• Climate is the average weather usually taken over a 30-year time period for a particular region and time period.

• Climate is not the same as weather, but rather, it is the average pattern of weather for a particular region.

• Weather describes the short-term state of the atmosphere.

Buzz words!• Atmosphere - The atmosphere covers the Earth. It is a thin layer of mixed

gases which make up the air we breathe. This thin layer also helps the Earth from becoming too hot or too cold.

• Temperature – How hot or cold the atmosphere is at any given point. Measured in degrees Celsius and Fahrenheit.

• Precipitation – Any form of water falling from the sky, for example water, snow, sheath and hail.

• Air pressure – The force per unit area exerted on a surface by the weight of air above that surface in the atmosphere of Earth.

• Cloud cover – The percentage or fraction of the sky that is covered by clouds

• Seasons - A season is a subdivision of the year, marked by changes in weather, ecology, and hours of daylight.
