Unit 2 AOS 1 Chapter 8 Characteristics of Pollutants

Unit 2: Earth's capacity to sustain life is affected by which of the following?

• Availability of resources

• Color of the sky

• Shape of mountains

• Number of continents

The chemical and physical characteristics of pollutants impact Earth’s four systems in which of the following ways, and what is a recommended approach for managing pollution impacts?

• They affect the atmosphere, hydrosphere, lithosphere, and biosphere differently, requiring a range of local and global management strategies.

• They only impact the atmosphere and require only local management.

• They have no significant effect on Earth’s systems and do not require management.

• They impact only the biosphere and can be managed by a single global policy.

Which of the following best summarizes the process of comparing agricultural systems for food security, evaluating ecological footprint analysis for future food and/or water security, and recommending options for improving food and/or water security in a specific region?

• Assessing different agricultural systems, analyzing ecological footprint, and proposing justified strategies for regional food and water security.

• Focusing only on traditional farming methods to ensure global food security.

• Ignoring ecological footprint analysis when planning for future food and water needs.

• Recommending a single universal solution for all regions regardless of local context.

Science can be applied to address the impacts of natural and human activities in the management of a selected pollutant and/or the maintenance of food and/or water security by:

• Developing technologies for pollution control and sustainable resource management

• Ignoring the effects of pollutants on ecosystems

• Relying solely on traditional farming methods without scientific input

• Allowing unchecked industrial waste disposal

Fill in the blank: The ______ and physical characteristics of pollutants influence dispersal of emissions from natural and manufactured sources.

• chemical

• thermal

• magnetic

• optical

Fill in the blank: The transport mechanisms, persistence, fate and toxicity of pollutants throughout Earth's four ______ systems are important to understand.

• interrelated

• isolated

• random

• separate

The impacts of a range of pollutants on the health and survival of living things in the biosphere, including humans, and on the quality of the atmosphere, hydrosphere and lithosphere, can be assessed with reference to risk, exposure, dosage, tolerance limits, LD50, chronic and acute toxicity, allergies, disruption of system regulation and ______ action.

• synergistic

• antagonistic

• enzymatic

• photolytic

Pollution is defined as:

• The presence of harmful substances in the environment

• The process of growing plants

• The movement of air in the atmosphere

• The natural cycle of water

Different types of pollution include:

• Air, water, soil, and noise pollution

• Only air and water pollution

• Only soil and light pollution

• Only noise and thermal pollution

Sources of pollution can include which of the following?

• Factories and vehicles

• Libraries and parks

• Hospitals and schools

• Museums and theaters
