People usually describe the temperature as hot or cold. The real definition of temperature is the measure of the average speed of air molecules. Temperature is measured in degrees by using a thermometer. They are rea
d in the shade because their measurements are too high when placed in direct sunlight.
Even though temperature changes every day and every season, the Earth's temperature is always in the right range to support life.
The temperature of the air depends on the temperature of the surface directly below. Also, the air feels colder as you climb up a mountain. This happens because the temperature decreases as you move away from the surface. The weather is strongly affected by the temperature.
