The document is a 7th grade science lesson about the atmosphere. It contains questions and answers about the composition of the atmosphere, how it traps heat and causes the greenhouse effect, and how certain gases like water vapor, carbon dioxide, and ozone absorb energy from the sun and rocks and trap heat in the atmosphere. It also mentions how clouds can help reflect heat back into space.
