Snowy Peaks in the Savanna

Temperature decreases with altitude:
Every 1000 metres it drops 6 degrees Celcius.

What is the temperature on the summit of a mountain of 2500 meter when the temperature is 25 degrees at sealevel?

Calculation

Rule: Every 1000 metres temperature drops 6 degrees Celcisu

Summit of the mountain (2500 m) = 25 degrees Celcius

2.5 x 6 = (12 + 3) = 15 degrees

Sea level (0 m) = 25 - 15 = 10 degrees Celcius

Rain in Summer

Temperature drops at higher altitude because:

Sun heats the Earth, the Earth heats the atmosphere.

Rules

• Warm air rises, cold air sinks.

• Warm air can hold more moisture than cold air.

• As air rises, its temperare drops. As air sinks, temperature rises.
