• Tropo means “turning” or “changing”.
• Contains most of the atmosphere’s mass.
• The weather forms here.
• Planes, balloons, and birds fly here.
• Ozone = a form of oxygen that contains three oxygen atoms in each molecule instead of two.
• Ozone converts the sun’s energy to heat, warming the Earth.
• Protects Earth from dangerous ultraviolet rays.
• Meso means “middle”.
• Protects Earth’s surface from being hit by meteoroids and other material from space by burning them up upon reentry.
• Thermo means “heat”.• Hottest layer because
sunlight strikes it first. • Extends into space, no
outer limit.• Broken into two sub
layers: ionosphere and exosphere.
• Energy from the sun causes gas molecules to become electrically charged particles called ions.
• These ions strike atoms in our atmosphere causing the atoms to glow.
Construct support for why your assigned layer serves an important role in the atmosphere, or why it’s beneficial to Earth.
