A farmer is evaluating (thinking about) four methods of preventing farm runoff from reaching the nearby rivers and streams.
Which is the best method for the farmer to use?
Build concrete canals on the farm to help water drain into a nearby lake.
Graze animals and plant crops on the sides of hills so that runoff flows more quickly.
Develop wide ditches filled with plants to give the runoff more time to soak into the ground.
Remove trees and grasses from the sides of the rivers and replace them with barriers made of rocks.
What effect would deforestation (cutting down the trees) most likely have on an ecosystem?
Loss of animal habitat
Loss of groundwater
Increase in species
Increase in precipitation
Where can you find most of Earth's available water?
Oceans
Glaciers
Lakes
Wetlands
Which of the following is a major source of air pollution?
Surface mines and landfills
Cars and coal-burning power plants
Construction sites and houses
Farmland and river
Air pollution causes the rain that falls on a pond to become more acidic. Over the next one or two years, how will the acidity most likely affect populations of plants and animals in the pond?
Populations will increase because the acid carries mineral nutrients into the pond.
Populations will become extinct because the acid is toxic and destroys their cells.
Populations will decrease because many organisms cannot tolerate acidic water.
Populations will increase because acid kills most disease-causing organisms.
Which of the following has the LEAST impact on wildlife habitat destruction?
Farming
Deforestation
Urban development
Weather patterns
Many scientists believe Earth's climate may be getting warmer because of human activities. According to these scientists, which human activities contribute the most to global climate change?
Landfill and urban development
Acid rain and dam construction
Car exhaust and industrial emissions
Farming and surface mining
A frozen popsicle was left in the sun and melted. Which statement is true regarding the physical properties of the popsicle after it melted?
It experienced a phase change.
The number of molecules had changed.
Its chemical composition had changed.
Its molecules were less energetic after it melted.
Which claim best demonstrates how air pollution in one place can affect another place far away?
Towns far away from factories and other sources of air pollution should not worry about the pollution.
Air pollution affects the land and water sources even if they are far away from the source.
Air pollution is only a problem in large cities because they produce extreme amounts of pollution.
Small towns only have to worry about air pollution from cars and trucks.
What are two reasonable solutions to protect the earth and its resources from air pollution?
Keep windows closed to prevent air pollution from coming into homes and other buildings.
Scientists and engineers can research and develop technologies and machines that produce less pollution and waste.
Relocate factories and industries to areas of low populations to lessen the impact of air pollution.
Develop and enforce laws that encourage manufacturers to reduce the amount of resources used and to lower the pollution produced.
Scientists and engineers can discover the source of pollution.
