The Atmosphere Unit Review

Which of the following best explains the curvature of the arrows for the westerlies and the trade winds?

• The ocean currents create winds flowing in a similar direction to the current.
• The Coriolis effect causes the winds to curve that way because the Earth rotates from left to right.
• The Coriolis effect causes the winds to curve that way because the Earth rotates from right to left.
• The sun is shining and warming the air from the right side of this diagram.

A jet stream is a wide band of low-speed winds that flow in the middle of the atmosphere.

• True
• False

The curving of the path of a moving object as a result of Earth's rotation is called the Coriolis effect.

• True
• False

A convection current is any movement of matter that results from differences in density.

• True
• False

The stratosphere is the top layer of the atmospehre

• True
• False

Which of the following is most responsible for the moving bands of air around Earth that are shown in the picture above?

• Conduction
• Convection
• Coriolis effect
• greenhouse effect

Which of the following is the direct source for these winds and currents?

• the uneven heating of Earth by the sun
• the Coriolis effect
• the rotation of Earth
• the sun is shining and warming the air from the right side of the diagram

The Coriolis effect greatly affects the paths of air circulation on Earth. What causes the Coriolis effect?

• the sun
• the moon
• Earth's rotation
• Earth's revolution

Which of the following describes the general pattern of winds near the equator?

• Winds are generally weak because the equator is a region where low and high air pressure atmospheric bands come together.
• Winds are generally strong because the equator is a region where low and high air pressure atmospheric bands come together.
• Winds are generally strong because the equator is a region of mostly high air pressure.
• Winds are generally weak because the equator is a region of mostly low air pressure.

Winds are named based on different factors. How are winds usually named?

• Winds are usually named based on their altitude.
• Winds are usually named based on their strength.
• Winds are usually named based on the direction in which they are blowing.
• Winds are usually named based on the direction from which they are blowing.
