New Unit 3 Review: Biodiversity and Human Population

Where do most tornadoes happen?

• Mexico

• California

• Canada

• Tornado Alley in the United States

One of the strategies being considered in Arboria to cope with the drought is the construction of a desalination plant to convert seawater into freshwater. How might this technology help mitigate the effects of the drought?

• By increasing the salinity of local water sources

• By promoting the growth of drought-resistant crops

• By reducing the need for water conservation efforts

• By providing an alternative source of freshwater

artificial embankments for preventing flooding

• allergies

• levees

• floodplain

• tributary

If the number of births in a population is the same as the number of deaths in a population, what will happen to the growth of the population?

• It will increase.
• It will decrease.
• It will stay the same.
• It will fluctuate.

What does a tornado warning mean?

• A tornado has been spotted by observers or indicated by weather radar.

• A tornado hasn't been spotted, but conditions are favorable for tornadoes to occur.

• It's a new Discovery Channel special on storm chasers.

• The conditions will be right for a tornado to form within your area in the next day or two.

If a disease that destroyed oak trees came through an ecosystem, what would happen to the acorn eating squirrel population?

• nothing - it would stay the same

• the squirrel population would increase

• the squirrel population would decrease

• none of the above

What is biodiversity?

• Biodiversity is the variety of plants on Earth.

• Biodiversity is the variety of life forms on Earth.

• Biodiversity is the study of rocks and minerals.

• Biodiversity is the process of weathering and erosion.

Which of the following is an example of how technology can reduce the impact of flooding?

• Building houses in flood-prone areas

• Constructing dams and levees

• Cutting down trees in floodplains

• Ignoring weather forecasts

Why did the earth's population begin to rise dramatically in the 1800s and continue?

• better medicines and healthcare were available

• better farming techniques allowed for more food production

• the Industrial Revolution allowed for technology to assist humans in transportation and mass production of goods

• All of these factors led to population growth

Why is biodiversity important?

• Biodiversity is important for ecosystem stability, essential resources, food security, and resilience to environmental changes.

• Biodiversity is only important for aesthetic reasons

• Biodiversity has no impact on ecosystem stability

• Biodiversity does not contribute to food security
