Temperature

The temperature you feel everyday is the temperature of the atmosphere. The degree of hotness and coldness of the air is known as temperature.

     The temperature of the atmosphere changes not only between day and night but also from season to season. Summers are hotter than winters.

     An important factor that influences the distribution of temperature is isolation.

Isolation is the incoming solar energy intercepted by the earth.

     The amount of isolation decreases from the equator towards the poles.

Therefore, the temperature decreases in the same manner.Now do you understand why poles are covered with snow?If the earth's temperature rises too high ,it would become too warm for some crops to grow.Temperature in cities is much higher than that of villages, The concrete and metals in buildings and the asphalt of roads get heated upr during the night.

      Also,the crowded high buildings of the cities trap the warm air and thus raise the temperature of the cities.

The standard unit of measuring temperature is degree Celsius. It was invented by Anders Celsius. On the Celsius scale the water freezes at 0°C and boils at 100℃.
