Unit 4 Weather

The diagram shows the trend of increasing global temperatures. Using the data in the diagram, which describes the MOST LIKELY effect on hurricanes experienced around the world?

• The intensity of the hurricanes will decrease because oceans will absorb less heat.

• The number of hurricanes will decrease because there will be less water in the oceans to evaporate.

• The number of hurricanes will increase because there will be increased evaporation due to higher water temperatures.

• The intensity of the hurricanes will stay the same because the rate of precipitation will decrease as the rate of evaporation increases.

What characteristic do thunderstorms, hurricanes, and tornadoes all share?

• They all form over dry and hot desert regions.

• They are all easily predicted by weather forecasters.

• They are all formed when warm and moist air rapidly rises.

• They always cause severe damage to land and property.

What kind of weather are people living on the equator most likely to experience regularly?

• cooler weather and more rain due to decreased evaporation

• warmer weather and more rain due to increased evaporation

• warmer weather and drier conditions due to faster evaporation

• cooler weather and less rain due to increased evaporation

• decreased precipitation

• thunderstorms

• tsunamis

How do weather fronts affect the formation of tornadoes?

• Tornadoes can form when one weather front moves in a circle.

• Tornadoes can form when one weather front reverses direction.

• Tornadoes can form when two weather fronts pass one another.

• Tornadoes can form when two weather fronts move into one other.

• warm temperatures and rain

• warm temperatures and clear skies

How does the Sun affect the movement of Earth's winds?

• It creates solar winds, which pushes air in Earth's atmosphere and result in currents.

• It warms Earth's surface unevenly, causing changes in air temperature and pressure.

• It has an uneven gravitational pull on Earth's atmosphere, causing changes in pressure and direction.

• It creates solar flares, which energize the winds around Earth's equator and cause them to increase in speed.

A student uses the setup shown below to model the effects of Earth's rotation on global winds. The line drawn in the middle represents Earth’s equator. As the student turns the balloon in the direction of the arrow, another student tries to draw a line downward, toward the equator to represent global winds. Which of the following does the model BEST show about the global winds just north of the equator?

• Earth is divided into equal halves, causing the global winds to blow in opposite directions near the equator.

• Earth’s equator is closer to the Sun, causing the global winds to be stronger there.

• Earth’s equator spins faster than the poles, causing the global winds to blow toward the east or left.

• Earth is round, causing the global winds to travel in curved lines.
