2.3 Act 3 WS - Earth’s Global Air Currents
1. Where does the majority of Earth’s the energy come from?
The Sun
2. Where is it warm year round on Earth?
Near the Equator
3. Surfaces heat the air (particles) above it so what is the air doing above
warm regions?
Rising since it is being warmed by the land
4. Draw an arrow on the picture of Earth below to show what direction the air
is moving above this warm zone. Draw an arrow on both sides of the
picture.
5. Where is it cold all year on Earth? Near the poles
6. What is the air doing above cold regions? Sinking
7. Draw an arrow to show what direction the air is moving above the cold
area. Then complete the convection cell by drawing additional arrows.
(Similar to your sea and land breeze convection cells)
8. Draw a particle diagram in each bubble to compare the particles motion.
9. The ___sun______ radiates energy. Earth receives more radiated energy
Faster/farther apart
polesand less near the ____poles___________. This
near the __equator______
makes the equator warmer, which means the particles are moving
_faster/farther apart_ and that makes the air _less__ dense so it
___rises_____. Colder air is _more_____ dense so it __sinks______. The
different temperatures and densities of the air cause movement. Air
moving is called __wind____.
