earth science final exam 2

What would MOST Likely result if more farms were develped along river basins in North carolina?

• an increase in water pollution

• an increase in rainfall

• an increase in invasive species

• an increase in severe weather

Which MOST OFTEN is a result of a warm air mass moving over a cooler air mass?

• a decrease in wind speed

• a decrease in cloud cover

• an increase in precipitation

• an increase in air pressure

What is the GrEATEST influence on wind speed?

• differences in the density of adjacent air masses

• differences in atmosphere nitrogen concentrations

• differences in atmospheric carbon dioxide levels

• differences in ozon levels in the atmosphere

Which is a major source of air pollution?

• planting more trees in a forest area

• building dams for hydroelectric power

• the production of energy using solar and nuclear power

• small farms raising large numbers of animals like cows

a brochure describes temperatures and annual rainfall for North Carolina. What aspect is the brochure focusing on?

• weather in North Carolina

• Climate in North Carolina

• ecosystems in North Carolina

• biomes of North Carolina

which is least likely to cause changes in global climate?

• a tsunami event

• an el nino event

• a volcanic eruption

• radiation from solar flares

What could increase the amount of greenhouse gases in the atmosphere?

• planting trees in areas that have been deforested

• reducing the use of gasoline powered vehicles

• burning coal to create electricity

• an increase in earthquake events around the globe

Which interaction of abiotic and biotic factors can help stabilize a forest area in North Carolina?

• increased precipitation, reducing soil erosion in the area

• increased decaying organic material, adding nutrients to the soil

• decreased water salinity, reducing biodiversity

• decrease number of predators, allowing prey to increase

what will MOST likely influence global sea levels?

• an increase in global temperatures

• an increase in global atmospheric nitrogen

• an increase in cyclone events around the globe

• an increase in earthquake events around the globe

How could a global decrease in plant diversity afffect the biosphere?

• it could increase the amount of oxygen

• It could increase animal diversity

• ite could decrease animal populations

• it could decrease the water available
