The greenhouse effect. The exchange of incoming and outgoing radiation that warms the Earth is often referred to as the greenhouse effect because a greenhouse works in much the same way.

Southern flying squirrels are adorable pet rodents that have the unique ability to glide through the air, just like sugar gliders. They can be found wild in the United States and can make a good pet for the right person. Names: Glaucomys volans, Southern flying squirrel, Assapan. Expected Lifespan: 10-12 years
Although they are known as flying squirrels, they do not actually fly - they glide through the air. Special type of the furry membrane (called patagia), stretched between wrists and ankles, serves as a parachute which supports squirrel while jumping from tree to tree. Flying squirrels can make 180 degree turns during gliding.
