Earth Science U 7 Test Review: Human Impacts on the Lithosphere

Increased development can create more ____ as a result of the replacement of large land areas with concrete and asphalt.

• flooding

• pollution

• forests

• condensation

​​​ (a)   ​ is the MAIN agent of erosion.

• Water
• Wind
• Gravity
• Glaciers

Deforestation would most immediately result in

• the loss of a native animal species

• the depletion of the ozone layer

• industrialization of an area

• global warming

Some factories in cities have a negative impact on the environment because they

• utilize agricultural technology that decreases soil erosion

• decreases the needs for resources

• require the use of fossil fuels for power

• limit the amount of emissions produced each year

Which human activity would have the most direct impact on the oxygen and carbon dioxide cycle?

• reducing the rate of succession

• decreasing the use of water

• enforcing laws that prevent the use of leaded gasoline

• destroying large forested areas

Deforestation will most directly result in an immediate increase in

• wildlife populations

• atmospheric carbon dioxide

• atmospheric ozone

• renewable resources

Some organizations are buying forest land in order to save those areas from being cut down or exposed to deforestation. The main reason for protecting these sections of forests is to

• provide more land for agricultural purposes

• cause the extinction of undesirable animal species

• prevent these trees from reproducing too fast

• maintain the diversity of the living environment

Increased urbanization/industrialization will most likely

• increase environmental carrying capacity for native species

• decrease available habitats

• increase the stability of ecosystems

• decrease global warming

Oxygen, Carbon Dioxide, and Water are ____________ that living things need

• natural resources

• organisms

• foods

• ions

A federal law requires mining companies to carry out ________, which is the process of restoring the land and vegetation to its original state after mining

• irrigation

• classification

• reclamation

• excavation
