is the ocean.
•
•
•
•
•
•
Lakes
Rivers
Marshes
Rain

How Do Earth’s Spheres Interact?
• Matter and Energy
– Change and cycle between
the spheres in two ways.
– 1. By exchange of matter.
• Water Cycle
• Nitrogen Cycle
I will be able to describe the parts of Earth’s System &
explain how matter & energy are transferred through it.
How Do Earth’s Spheres Interact?
• Matter and Energy
– 2. By exchange of energy
• Moves back and forth
between spheres.
• Solar Energy
– Drives winds and Weather
– Plants use it to make food.
» Animals eat plants for
energy.

explain how matter & energy are transferred through it.
What is the Source of Earth’s Energy?
• Earth’s Energy
– Most comes from the Sun.
– A tiny fraction
• Ocean Tides
• Geothermal
– Lava & Magma
– Moves or Changes form
– Not created or destroyed.
– Transferred between
spheres

What is the Source of Earth’s Energy?
• Energy Budget
– A way to keep track
of energy transfers
into and out of
Earth’s system.
– Unbalanced budget
• Can increase or
decrease Earth’s
temperatures.
I will be able to describe the parts of Earth’s System and
explain how matter and energy are transferred through it.
What can disturb Earth’s Energy Budget?
