Why Earth Science?
• Because nearly everything we do each day is
connected in some way to the Earth: to its
land, oceans, atmosphere, plants, and animals
• Because just as Earth systems directly affect
us, we - as individuals, communities and
nations - affect our planet
• Because we LIVE on Earth!!

see that all its parts - the living things, the air, the water, the
ice, and the rocks - are connected. Everything on Earth is part
of ONE system.
This iconic picture taken from Apollo 8 in 1968 changed how
scientists, and the general public, view our Earth.
As a result, the ideas of Earth System Science was developed.
