Hot and Cold
You may describe the weather to be hot or cold. This is also how we think of temperature . Even though the temperature changes every day and every season, the Earth's temperature
is always in the right range to support life.
The air feels colder as you climb up a mountain. This happens because the temperature decreases as you move away from the surface.
Scientists measure temperature with a thermometer. They are placed in the shade because they will tell the wrong temperature if it is in direct sunlight.
