Weather EOG Review

In which way are evaporation and condensation similar? 

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

Which is most responsible for the uneven heating of the air in the atmosphere?

• convection

• radiation

• conduction

• condensation

Which best describes why winds at the beach change direction between day and night?

• because the temperatures over land and over water change 
• because warm air over land sinks and stays in place over land 
• because cool air rises and is replaced by warm air from the ocean 
• because cool air sinks and stays in place over land 

Which will most likely result from a low-pressure weather system? 

• warm temperatures 
• cloudy conditions 
• clear conditions 
• cool temperatures 

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 Pacific 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. 

Which has the greatest effect on wind speed? 

• precipitation 
• cloud cover 
• wind direction
• air pressure 

After a rain, a puddle of water remains on a sidewalk. After a day of sunshine, the puddle is gone. Which process is most responsible for the disappearance of the puddle?

• precipitation 
• transpiration
• evaporation
• condensation 

On a cold, cloudy day, the local weather forecaster predicts that a high-pressure system will be moving into the area in the next 24 hours. Which weather conditions will this system most likely bring to the area? 

• stormy 
• sunny 
• snowy 
• hot 

Which best describes a characteristic of the 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 the hot air along the equator to rise to areas in North America. 
• It causes high pressure air masses to rotate clockwise.

What must occur before clouds can form? 

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