Essential Question:

•Why does sinking air cause areas of high pressure?

Answer

•Sinking air causes areas of high pressure because sinking air presses down on the air beneath it.

Essential Question:

Key terms:• Radiation: the transfer of energy

as electromagnetic waves• Thermal conduction: the

transfer of energy as heat through a material

• Convection: the transfer of thermal energy by the circulation or movement of a liquid or gas

Key Terms

•Wind: the movement of air caused by differences in air pressure.

•Coriolis effect: the apparent curving of the path of an object from a straight path due to the Earth’s rotation.

Essential Question:•What processes allow atmospheric gases to be constantly used and renewed?

Key Term:•Radiation balance: the

balance between incoming energy and outgoing energy within the atmosphere.

Content Objective:

•Differentiate between the layers of Earth’s atmosphere and identify the physical properties of each layer

Essential Question:•Why does temperature decrease as altitude increases in the troposphere, while temperature increases as altitude increases in the stratosphere?

Key TermsEasterlies: prevailing winds that blow from east to west between 60º and 90º latitude in both hemispheres.

Westerlies: prevailing winds that blow from west to east between 30º and 60º latitude in both hemispheres.

Trade winds: prevailing winds that blow from east to west from 30º latitude to the equator in both hemisphere
