“Global warming is a gradual increase in the earth’s temperature generally due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.

All living beings depend on the atmosphere for their survival. Atmosphere provides them the air they breathe. It protects them from the harmful effects of the sun’s rays. Without its protection, they would be baked alive by the heat of the sun during day and get frozen during night.

The hot surface of earth heats the air near it. Air from high pressure area moves towards the low pressure area. The air moving from high pressure area to low pressure area is called wind. So, it is the sun’s heat which causes wind to blow and gives us windy weather.

Atmospheric pressure is an indicator of weather. When a low-pressure system moves into an area, it usually leads to cloudiness, wind, and precipitation. High-pressure systems usually lead to fair, calm weather. A barometer measures atmospheric pressure, which is also called barometric pressure.

The temperature of human body normally does not go below 35°C. Hence the temperature range marked in it is 35°C to a maximum of 42°C in Celsius scale OR 94°F to a maximum of 108°F in Fahrenheit scale. Laboratory Thermometers: These are used in laboratories for scientific research.

Humidity is amount of water vapours or moisture present in the air.

Laboratory thermometer is used to measure the temperature of things other than human body. The daily maximum and minimum temperatures reported in weather reports, are all measured by a thermometer known as the Maximum minimum thermometer.
