6. What is the movement of air from an area of high
pressure to an area of low pressure?
What causes the wind to blow?
What is the weight of air pressing down on Earth? It can
change from place to place, causing air to move, flowing
from areas of high pressure toward areas of low pressure.
Because the Earth is ______
areas of Earth receive different amounts of radiation from
the sun.
Describe the air at the EQUATOR.
Describe the air at both POLES (north & south).
The Sun’s uneven heating of Earth’s surface forms?
The rotation of Earth causes moving air & water to turn to the right north of the equator and to the left south of the equator?
Due to the CoriolisEffect, object deflect to the
______and
objects deflect to the ______.
GLOBAL WINDS
What are the wind patterns that are caused by the giant CONVECTION currents combined with the CORIOLIS EFFECT?
Early sailors discover that the wind patterns on Earth helped
them navigate the oceans. Near the equator, sailors
sometimes found little or no wind at all to move their ships,
it rained nearly every afternoon. This area near the
equator where very little wind occurs is called?
What are the 3 types of GLOBAL WINDS?
A.
B.
C.
What is the JET STREAM?
The JET STREAM moves STORM SYSTEMS across North
America from which direction?
What happens if an airplane flies within the JET STREAM?
What direction does the plane need to be flying fromin
order to catch the jet stream?
Choose 2 states that this could happen between?
LOCAL WINDS
GLOBAL wind systems determine the ______weather patterns for the ______planet.
However…
What do SMALLER wind systems affect?
What are the 2 types of LOCAL WINDS?
Label the Following Diagrams
Label the GLOBAL WIND PATTERNS, latitudes & draw arrows
Label the CORIOLIS EFFECT Diagram by drawing and labeling
the Northern Hemisphere, Southern Hemisphere, Equator,
and the arrows to show the wind deflections.
Label each diagram as CONVECTION, RADIATION &
CONDUCTION
Label AND describe warm air and cold air in convection currents.
REVIEW: READ AND ANSWER
Heat moves in the atmosphere the same way it moves through the solid Earth or another medium. What follows is a review of the way heat flows, but applied to the atmosphere. Radiation is the transfer of energy between two objects by electromagnetic waves. Heat radiates from the ground into the lower atmosphere. In conduction, heat moves from areas of more heat to areas of less heat by direct contact. Warmer molecules vibrate rapidly and collide with other nearby molecules, transferring their energy. In the atmosphere, conduction is more effective at lower altitudes, where air density is higher. This transfers heat upward to where the molecules are spread further apart or transfers heat laterally from a warmer to a cooler spot, where the molecules are moving less vigorously. Heat transfer by movement of heated materials is called convection. Heat that radiates from the ground initiates convectioncells in the atmosphere. Different parts of the Earth receive different amounts of solar radiation. Which part of the planet receives the most solar radiation? The Sun's rays strike the surface most directly at the Equator. The difference in solar energy received at different latitudes drives atmospheric circulation.
What is moving in conduction? What is moving in convection?
Why do the poles receive less solar radiation than the Equator?
What drives atmospheric circulation?
What powers our weather?
What does heat cause?
How does the tilt of the Earth affect heating?
What causes wind?
