কারণ ও প্রেক্ষাপট

The atmosphere is the gaseous envelope surrounding Earth, structured into layers by temperature and composition. The governing relationship is: Gravity retains gases while solar radiation drives heating, convection, circulation and chemical reactions through the atmospheric column.

কীভাবে কাজ করে

Gravity retains gases while solar radiation drives heating, convection, circulation and chemical reactions through the atmospheric column.

মূল তথ্য

• The troposphere contains most weather and most atmospheric mass.
• The stratosphere contains the ozone layer and warms upward through ozone absorption of ultraviolet radiation.
• The mesosphere is the coldest major layer; the thermosphere absorbs high-energy radiation.
