6.BOWER WIND and OCEAN CURRENTS

What causes wind?

• low pressure

• Air moves from regions of high pressure to regions of low pressure.

• high pressure

• weather patterns

When two air masses of different densities collide, it's called__________.

• a front

• a high pressure zone

• hurricane

• storm

Which of the following statements best describes how the Gulf Stream affects the weather along the east coast?

• It makes the air less humid and brings less rain to the area

• It makes the air temperature warmer and the air more humid

• It makes the air temperature cooler and the winds stronger

• It makes the wind stronger and brings less rain to the area

Which best describes a characteristic of a jet stream?

• It forms a boundary between a cold air mass and a warm air mass

• It creates the high winds around the eye of a hurricane

• It forces hot air along the equator to rise to areas across North America

• It causes high pressure air masses to rotate clockwise

Why are ocean currents important to coastal regions?

• They can warm or coool the air temperatures along coastal regions.

• They produce high and low tides along coastal regions

• They produce warm air temperatures along coastal regions

• They increase the rate of precipitation as cold water moves along coastal regions

What happens to the temperature RANGE near the ocean?

• the range is usually smaller

• the range is usually bigger

• it does not matter

• They stay the same

Why does weather tend to move eastward across the central United States?

• Global winds blow generally from west to east in the middle latitudes. Mountain breezes blow from the western mountains across the country.

• Warmer air from the West Coast tends to spread out toward cooler air over the East Coast.

• Air moves from higher air pressure over the Pacific Ocean to lower air pressure over the Atlantic Ocean.

If the ocean water is warmer than the air above it, will thermal energy be transferred from the water to the air, and will the temperature of the air increase?

• The ocean water will transfer thermal energy to the air, which will increase the temperature of the air.

• The ocean water will transfer thermal energy to the air, but that will not affect the temperature of the air.

• The ocean water will increase the temperature of the air, but it will not transfer thermal energy to the air.

• The ocean water will not transfer thermal energy to the air, and it will not increase the temperature of the air.

Is sunlight more intense

• at the equator

• a few degrees latitude above the equator

• at south pole

• at the north pole

jet stream is a fast moving air current found in the upper levels of the atmosphere. How does the jet stream over the United States most influence weather patterns?

• Weather patterns move from west to east across the United States

• The jet stream increase precipitation in local areas

• The jet stream causes higher temperatures in desert areas

• The jet stream causes lower temperatures in Canada and higher temperatures in the United States
