The balance between incoming solar energy and out going energy radiated into space is

Based on the physics principle of conservation of energy, this radiation budget represents the accounting of the balance between incoming radiation, which is almost entirely solar radiation, and outgoing radiation, which is partly reflected solar radiation and partly radiation emitted from the Earth system, including the atmosphere.

Alkaline earth metals are found in group 2 of the periodic table.
