Why does wind between the equator and 30 degrees south come out of the southeast? Cooled air moves east toward the equator and is deflected toward the north by the Coriolis effect. Cooled air moves south toward the equator and is deflected toward the west by the Coriolis effect. Cooled air moves north toward the equator and is deflected toward the east by the Coriolis effect. Cooled air moves west toward the equator and is deflected toward the south by the Coriolis effect. Cooled air moves north toward the equator and is deflected toward the west by the Coriolis effect.

Cooled air moves north toward the equator and is deflected toward the west by the Coriolis effect.

Why does air tend to rise in equatorial regions? Equatorial regions receive less indirect sunlight than other areas. Equatorial regions receive more indirect sunlight than other areas. Equatorial regions receive less direct sunlight than other areas. Equatorial regions receive more direct sunlight than other areas.

Equatorial regions receive more direct sunlight than other areas.

Determine which line on the graph represents Urbana and which represents San Francisco and label each for the correct city. Indicate how you figured this out by answering the question below.

The weather on four different summer days is described below. On which day would you expect the greatest temperature range? Which day would have the smallest range in temperature?

Greatest Temp Range: -Clear skies during day and clear at night Inter. Temp. Range: -Clear skies during day and cloudy at night -Cloudy skies during day and clear at night Small Temp Range: -Cloudy during day and cloudy at night

The image below shows that about 30 percent of the Sun's energy is reflected and scattered back into space. How would a 50 percent increase in Earth's albedo impact average surface temperatures? Surface temperatures would increase, causing a decrease in surface water and/or ice on Earth, and would thus cause a further increase in albedo. Higher albedo would result in cooler temperatures on Earth. A higher albedo means more of the Sun's radiation is absorbed by Earth's surface. Ice sheets would advance, thereby increasing Earth's overall albedo and further cooling Earth's surface.

Higher albedo would result in cooler temperatures on Earth. Ice sheets would advance, thereby increasing Earth's overall albedo and further cooling Earth's surface.

Circulation in the atmosphere is influenced by whether the planetary body is rotating or nonrotating. Sort the following features by whether they apply to a rotating Earth, a nonrotating Earth, or neither.

Non rotating: -all surface air flows toward the equator -one pair of convec cells Rotating: -equatorial and subpolar air -presence of trade winds -three pairs of convec cells Neither: -all surface air flows poleward -air sinks at equator

How does the location of the Intertropical Convergence Zone (ITCZ) change over time? The ITCZ migrates north of the equator in Northern Hemisphere winter and south of the equator in Northern Hemisphere summer. The ITCZ migrates south of the equator in winter and north of the equator in summer. The ITCZ migrates south of the equator in Northern Hemisphere winter and north of the equator in Northern Hemisphere summer. The ITCZ migrates north of the equator in winter and south of the equator in summer.

The ITCZ migrates south of the equator in Northern Hemisphere winter and north of the equator in Northern Hemisphere summer.

A jet stream generally diverges above a low-pressure (warm) center. However, at Earth's surface, air converges at a low-pressure center. If the divergence of the jet stream is greater than the convergence of air at the surface low-pressure center below it, what will happen to the surface winds? The surface winds will not change. The surface winds will likely get weaker. The surface winds will likely get stronger. The surface winds will begin to move downward.

The surface winds will likely get stronger.

This air is cool and dry.

Of the following statements about the transfer of heat on Earth, which is/are true? Choose all that apply. Water vapor in the air carries latent heat with it, which is released in other areas. Air currents move warmer air from the tropics to higher latitudes. Ocean currents move warm water from the tropics to higher latitudes. Earth's albedo reflects back into space all of the sunlight hitting Earth. Greenhouse gases in the air decrease the amount of heat retained by Earth's atmosphere.

Water vapor in the air carries latent heat with it, which is released in other areas. Air currents move warmer air from the tropics to higher latitudes. Ocean currents move warm water from the tropics to higher latitudes.

In which direction would winds move at the poles if Earth rotated in the opposite direction? Wind would move toward the southeast at both poles.

Wind near the north pole would move to the northwest, and the wind near the south pole would move to the southwest.

Wind near the north pole would move to the northeast, and the wind near the south pole would move to the southeast.
