Which best explains why a nearby body of water tends to make local temperatures milder?

• Water constantly releases heat into the air.

• Water gains and loses heat more slowly than land.

• Some water stays liquid when everything else is froze.

• When water is frozen it protects nearby area from wind.

What conditions will result in high winds?

• A large difference in air pressure

• Heavy rains over several days

• Increase in evaporation rates

• Presence of cirrus clouds

What weather change is most likely to happen if air pressure is falling?

• The weather will become warmer.

• The weather will become stormy.

• The weather will become cooler.

• The weather will become fair.

• More areas will become cooler and moister.

• More areas will experience increased snowfall.

What impact does the Gulf Stream have on North Carolina's coastal climate?

• The cold water from the Gulf Stream current cools the land.

Which best explains why there is wind in Earth's atmosphere?

• The evaporation of water

• The uneven heating of Earth

• The movement of birds and planes

• The pull of the ocean currents and tides

What type of weather information would be most helpful in forecasting future tornadoes?
