Science EOG Review - Day 1

In North Carolina, the wind is blowing from the north. If the wind changes direction and begins to blow from the south, what will most likely result?

• The temperatures will increase.
• The temperatures will decrease.
• The air pressure will increase.
• The wind speeds will decrease.

What must occur before clouds can form?

• Water vapor must lose heat energy.
• Water vapor must get warmer.
• Precipitation must begin to fall and run off.
• Transpiration must add water vapor to the atmosphere.

Global atmospheric patterns are responsible for most local weather. Which causes these patterns to exist?

• unequal heating of Earth
• mountain ranges
• greenhouse gases
• holes in the ozone layer

Which processes occur when a pot of water placed on a hot stove causes the water to boil?

• The pot heats because of conduction, and convection causes movement of the water.

• The pot heats because of conduction, and radiation causes movement of the water.

• The pot heats because of radiation, and convection causes movement of the water.

• The pot heats because of convection, and conduction causes movement of the water.

Which is the best example of a physical change?

• water in a cup turning into ice
• wood burning to ashes
• cake mix baking into cupcakes
• a piece of metal rusting

James measured the temperature outside his house everyday for 2 months. He observed that on days the sky was mostly cloudy, the temperature was an average of 9 degrees cooler than days the sky was mostly sunny. Which best describes the reason for this pattern?

• The clouds blocked radiation from the sun, causing cooler temperatures.

• The clouds blocked conduction from the sun, causing cooler temperatures.

• The clouds allowed more radiation from the sun to reach the Earth's surface.

• The clouds allowed more conduction from the sun to reach the Earth's surface.

In which way are evaporation and condensation similar?

• Both are caused by changes in heat energy.
• Both cause decreases in air temperature.
• Both cause increases in air temperature.
• Both are caused by the warming of the atmosphere.

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

• The warm water from the Gulf Stream current warms the land.
• The cold water from the Gulf Stream current cools the land.
• The cold water from the Gulf Stream current decreases inland wind speeds.
• The warm water from the Gulf Stream current increases inland wind speeds.

Water droplets forming on the outside of a cold glass of water on a hot, summer day is an example of which part of the water cycle?

• condensation

• evaporation

• precipitation

• transpiration

Which is the best explanation for how air masses move across the United States?

• The prevailing westerlies move air masses from west to east across the United States but may be deflected by the jet stream.
• The trade winds move air masses from west to east across the United States.
• The jet stream moves air masses from the Atlantic Ocean across the United States.
• The warm air of the Gulf Stream causes air masses to move from the Atlantic Ocean to the Pacific Ocean.
