Lesson 7: Global Cycles of Matter

matter can leave Earth but cannot enter

no matter enters or leaves Earth

matter can enter Earth but cannot leave

matter enters and leaves Earth in cycles

the amount of matter in a closed system always stays the same

the amount of matter in a system, closed or open, always stays the same

the amount of matter in a closed system decreases as the amount of energy increases

the amount of matter in an open system increases as the amount of energy decreased

Energy cannot enter or leave Earth's biosphere

Energy can enter and leave Earth's biosphere

Energy can leave but cannot enter Earth's biosphere

Energy can enter but cannot leave Earth's biosphere

A meteor falls toward Earth

A spacecraft enters space

An airplane soars above clouds

A shooting star lights up the night sky.

deposited onto the organisms and environments on Earth from the atmosphere

taken from the organisms and environments on Earth and given to the atmosphere

transferred among the organisms and ecosystems on Earth and the atmosphere

created by the organisms and environments on Earth and transferred to the atmosphere

Sunlight warms liquid water

An increase in predators creates a shortage of water

Water molecules evaporate from the soil and combine to become clouds

A producer takes up water molecules from the soil and uses them to make other molecules

water vapor rises and cools

water molecules produce clouds

humans collect water when it rains

water molecules fall back to Earth's surface

atmosphere only

living things only

terrestrial and aquatic

living and non-living

through plants

through sunlight

through respiration

through the water cycle
