🧗 Climb the mountain
Drag the climber up the slope. Watch what happens to the temperature, the air and the plants as you go higher.
🌳 Forest zone. Tall trees give shelter from the wind.
*Example only. Air usually cools about 3.5°F for every 1,000 ft you climb, so we start at 70°F at sea level. Real temperatures depend on the place, season and weather. Air thins as you climb: near the top of Mount Everest, each breath holds only about one-third as much oxygen as at sea level.
