PowerPoint Presentation: Climate By - Arti Chaudhary What is climate? : What is climate? Climate is the average weather condition of a place over a long period of time. What is weather?: What is weather? The weather is just the state of the atmosphere at a particular place and time, including things such as temperature, precipitation, air pressure and cloud cover. Climatologist: Climatologist People who study climate . Meteorologist : Meteorologist People who forecast weather are called meteorologists. They are able to do so with the help of satellite. FACTORS INFLUENCING CLIMATE : FACTORS INFLUENCING CLIMATE Latitude Height above the sea level Wind Distance from the sea Humidity LATITUDE: LATITUDE The Earth is spherical, so the Sun's rays don't fall evenly on the land and oceans. Equatorial region receives direct sun rays hence bringing these areas more warmth. The polar regions like Arctic circle 66 ½ degree north and Antarctic circle 66 ½ degree south receive almost no sunlight through out the year hence forming the coldest part of the earth.

TEMPERATE ZONE - PowerPoint Presentation: FRIGID ZONE OF THE EARTH North Pole South Pole Arctic Circle 66° 30′ N Antarctic Circle 66° 30′ S North Frigid Zone South Frigid Zone PowerPoint Presentation: The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere like water vapor, carbon dioxide, nitrous oxide, and methane trap energy from the sun. Without these gases, heat would escape back into space and Earths average temperature would be about 60ºF colder and would not be warm enough for humans to live. But if the greenhouse effect becomes stronger, it could make the Earth warmer than usual.

Areas that are located at high altitude have a cold climate. PowerPoint Presentation: Altitude is the distance above sea level. As you go higher up a mountain, the air pressure decreases and the gas molecules spread farther and farther apart. Less dense air holds less heat than dense air, so the farther above sea level you are, the lower the temperature will be. WIND: WIND Sea breeze (day) Land breeze (night) Land heated by the sun Land cooled by radiation Wind is caused by the uneven heating of the air around the earth. Warm air rises and is replaced by cool air. This produces wind which contains heat and moisture. PowerPoint Presentation: DISTANCE FROM THE SEA AND HUMIDTY ARE TWO MORE FACTORS WHICH AFFECTS THE CLIMATE.
