Which two things interact MOST in the water cycle?

• oceans and the Moon

• oceans and the Sun

• lakes and the Moon

• lakes and the Sun

Water vapor sometimes condenses into stratus clouds that are in contact with the ground. What forms as a result of this process?

• ozone

• methane

• fog

• smoke

Which best describes how relative humidity would change if the air temperature decreased?

• It would increase.

• It would decrease.

• It would stay the same.

• There is no relationship between relative humidity and air temperature.

A high-speed wind, called a jet stream, is moving from the west to the east across the United States. Which characteristic of this jet stream is MOST important in predicting weather patterns?

• The jet stream controls the speed of surface wind.

• The jet stream controls the direction of surface wind

• The jet stream separates moist northern air from dry southern air.

• The jet stream separates cold northern air from warm southern air.

Hurricanes are large tropical storms with heavy winds that exceed 74 miles per hour. Hurricanes produce heavy rains and may give rise to tornadoes. What is the source of the energy contained in hurricanes?

• thermal energy of ocean waters

• kinetic energy of ocean waves

• thermal energy of coastal lands

• mechanical energy of moving air

Which two factors are MOST responsible for a flash flood?

• the distance from rivers and the time when it rains

• the temperature of the rain and the tiem since it last rained

• how much rain is falling and how long the rain lasts

• how far the water must flow and the time of the year it is raining

The reading on a barometer rises when the air

• pressure increases.

• pressure decreases

• speed increases

• speed decreases

Which most likely impacts the rotation of a hurricane that forms in the Atlantic Ocean?

• jet stream

• Gulf Stream

• Coriolis effect

• humidity levels

Which cloud is most likely to bring thunderstorms?

• altostratus

• cirrus

• cumulonimbus

• stratus

On a weather map, which is being measured at locations with the same isobars?

• rainfall
