During this era, ocean and atmosphere were formed. It describes how the Earth's crust is made up of plates that slowly move around, occasionally pushing underneath each other or colliding. The atmosphere protects life on earth by absorbing ultraviolet solar radiation, warming the surface through heat retention, and reducing temperature extremes between day and night. INTRODUCTION Earth's energy budget refers to the tracking of how much energy is flowing into and out of the Earth's climate, where the energy is going, and if the energy coming in balances with the energy going out.
