Earth and all of the air in the atmosphere around it make
up an incredibly complex system. Energy is constantly
changing forms in many different ways.
How would scientists most likely describe the system of
the Earth in regard to energy?
O
Earth is a
Earth is an isolated closed system because energy only
escapes the system as heat travels into space.
Earth is an isolated closed system because the
atmosphere allows energy from the Sun to enter as heat.
Earth is an open system because the atmosphere stops
energy from escaping into space.
Earth is an open system because heat energy from the
Sun enters through the atmosphere.
