The atmosphere is essential for life because it maintains a suitable climate for sustaining life. It does so by: Maintaining proper temperatures throughout day and night. It keeps the average temperature of Earth constant during day and prevents the heat from escaping during the night. The atmosphere contains the gases that we need to stay alive (Eg, oxygen). It acts like a protective blanket. It does not allow harmful UV radiations from reaching us. Without the atmosphere the water cycle would not be possible.
