Earth Science Pre Test

What are some consequences of deforestation?

• increased population in cities
• building of more infrastructure
• soil erosion, loss of ability of trees to remove CO2 from the atmosphere
• more mercury and cyanide released into rivers

Flash flooding often occurs in city areas because

• Roads, pavements, and buildings reduce the infiltration of water into the ground
• Ground water storage is usually very large
• unoff decreases during precipitation
• The heat generated by city areas decreases actual evapotranspiration

What is a negative impact of mining?

• Material left after ore is extracted can release toxic chemicals into the groundwater

• Mining can improve the air quality where miners work

• Quarries attract new species to the area

• Mining can decrease soil erosion

What is a negative impact of agriculture?

• Fertilizer runoff polluting rivers

• More land for animals to graze

• Less food available

• Increases atmospheric oxygen

Crop rotation is used in order to

• Provide alternative crops to the public

• Maintain the nutrient health of the soil

• Encourage pest diversity and growth

• Assure development of new pesticides

What is the underlying force that drives plate tectonics?

• Ocean tides

• Volcanic eruptions

• The rock cycle

• Convection currents

Which of the following plate interactions is most likely to form a mountain range?

• A transform boundary between ocean plates

• A transform boundary between continental plates

• A convergent boundary between continental plates

• A subduction zone between a continental plate and an ocean plate

Name the boundary

• convergent boundary
