1. Which of these would most likely cause the number and strengths of hurricanes that hit Texas to increase?

• Fewer ocean tides
• Lower humidity
• Warmer ocean water
• More melting glaciers

2. Sunlight heats the land and water at different rates. During the day the heated land quickly heats the air over it more than the air over the ocean causing a convection current. Which diagram best shows the formation of a convection current at the beach?

• 
• 
• 
• 

3. The weather map shows the weather conditions for one day across the United States. Based on the weather map, which city will most likely experience heavy rainstorms during the next 24 hours?

• Los Angeles
• Houston
• St. Louis
• Washington D.C.

4. The weather map shows the weather conditions for one day across the United States. Based on the weather map, what will be the weather like in Texas during the next 24 hours?

• Overcast
• Heavy rain
• Light rain

5. Which diagram best represents convection currents?

• A
• B
• C
• D

6. Which statement BEST describes what happens when a cold front approaches a warm front?

• The cold air mass will push the warm air mass upwards.
• The cold air mass will slide over top of the warm air mass.
• The cold air mass will retreat from the warm air mass.
• Cold fronts have no affect on warm fronts when they come together.

7. In some parts of the world hurricanes are called typhoons. The map below shows where typhoons form and the paths they usually follow. Typhoons do not generally form in the area at X. What is missing in area X that would allow typhoons to form there?

• Microscopic organisms
• Salty ocean water
• Warm ocean water
• Ocean waves

8. The boundary between two air masses with different temperatures is known as which of the following?

• Atmosphere
• Front
• High Pressure system
• Low Pressure system

9. Why do hurricanes lose strength when they move over land?

• There is no longer a source of warm, moist air.
• There is not enough energy coming from the Sun.
• Evaporation and condensation cannot take place over land.
• The winds on the land cancel out the winds of the hurricane.

• A: Cold Water, B: Cold Water
• A: Cold Water, B: Warm Water
• A: Warm Water, B: Cold Water
