Water is heavy so it stays in the troposphere.

So, all weather happens in the bottom layer of the atmosphere.

The troposphere is about 5-11 miles deep (26,000 to 60,000 ft). It is the layer closest to earth and contains most of the air. The troposphere is where weather happens. Temperatures drop as you move away from the earth (go higher). The top part of the troposphere is called the tropopause. It acts like a lid to keep water vapor and other heavy greenhouse gases in the troposphere. The temperature stops dropping and remains at -76°F.

+136°F Libya Africa;

-129°F Antarctica;

-80°F Alaska

Moon: +253°F to -387°F

Space: -454°F absolute zero: -459°F




The earth’s atmosphere spreads out the heat from the sun, so the earth has an even temperature. The worldwide average temperature on the ground or standard atmospheric temperature is 59°F or 15°C.

Does earth’s average atmospheric temperature always stay the same or does it change over time? What could cause it to rise or drop? Earth’s average temperature changes constantly!


Atmosphere and Ocean - 5


Things that could change the atmosphere and ocean content and temp of the earth:

(1)volcanic eruptions/plate tectonics, (2) pollution, (3) earth’s tilt (Milankovitch cycle), (4) sun spots.
