Grade 6 Trimester #2 District Assessment #2

Which example best shows how the water cycle carries on energy transfer?

• a flooding river depositing silt on a floodplain

• a warm ocean current warming the air above it

• ocean water depositing sand particles on a shore

• water seeping through the soil and dissolving salts

Which type of data confirms that one air mass is being replaced by another air mass in a particular area?

• high wind speed

• high air pressure

• high air temperature

• high levels of humidity

How would this graph look different during an El Niño year?

• A. Beginning in May, the ocean temperatures would be lower for several months.

• B. Beginning in December, the ocean temperatures would be higher for several months.

• C. The ocean temperatures would be higher in summer months but the same in winter months.

• D. The graph would look the opposite, with the ocean temperatures in the winter months being warmer than in the summer months

Which two processes would be responsible for cloud formation in a hurricane?

• freezing and condensation

• evaporation and precipitation

• evaporation and condensation

• condensation and precipitation

One of the elements used to help predict weather includes measuring the amount of water vapor in the air. What does this describe?

• humidity

• wind speed

• air pressure

• temperature

How does the sun’s energy most directly influence precipitation in an area?

• The sun’s energy drives the water cycle, which determines precipitation.

• The sun’s energy controls the amount of condensation and therefore precipitation.

• The sun’s energy powers the water cycle by causing runoff, which leads to precipitation.

• The sun’s energy creates surface currents in oceans that bring precipitation to different areas.

Which factors are most important to know when describing the climate of a region?

• direction of prevailing winds

• current air pressure and humidity

• recent high and low temperatures

• average temperature and precipitation

This map shows the air pressure systems and fronts for a single day. Based on this map, which prediction can be made?

• The warm front will move south.

• The cold front will move southeast.

• The area most likely to have precipitation is in the western area of the country near the Pacific Ocean.

• The area most likely to have no precipitation is in the north central area of the country near Canada.

The causes of weathering and erosion are:

• natural forces like wind and water

• human activities

• both natural forces and human activities

• none of the above

This model shows global ocean currents. How does this model demonstrate the effect of unequal heating of the sun on global currents?

• By showing temperature variations across different latitudes

• By illustrating the Coriolis effect on water movement

• By depicting the salinity levels in various ocean regions

• By highlighting the impact of wind patterns on ocean currents
