Which two natural resources are matched correctly with their environmental impacts in the table?
timber and freshwater
coal and timber
coal and solar energy
freshwater and solar energy
In a city, home-heating from coal and local timber increased by 30% in a single year.
As a result, which direct impact to the local environment will most likely happen?
Soil erosion in the area will decrease.
Forests in the area will grow much faster.
Carbon dioxide concentrations in the air will increase.
Lakes, rivers, and streams will become less polluted.
Which conservation example demonstrates resource recycling?
using solar heaters to keep houses warm
using a plastic grocery bag more than once
transforming used glass or plastic bottles into new products
riding a bike to school or work instead of driving a car

In a local town, more than 50% of home owners installed solar heaters to keep their homes warm instead of using electricity from coal that comes from a different state.
How will this decision impact the local environment?
There will be a decrease in local deforestation.
There will be an increase in acid rain as result of the increased coal conservation.
There will be an increase in local smog from the coal fired power plants.
There will be a decrease in local greenhouse gas emissions.
Hydropower generates over 60% of the world's renewable energy. What could be an environmental impact of this method of power generation?
It emits greenhouse gases.
It produces air pollutants.
It contaminates groundwater resources.
It results in the destruction of plant and animal habitats.
The photograph shows a solar energy farm near Seville, Spain.
The mirrors reflect incoming sunlight toward the solar tower in the center, where the energy from the sun is turned into electricity. Why are mirrors used to reflect the sunlight?
to diffuse the incoming solar radiation
to concentrate the energy from solar rays
to drive the process of nuclear fission
to create heat for burning coal
A substance is composed of organic material such as dead plants. To which category does the substance belong?
magma
mineral
ore
soil
What is the relationship between particle size and permeability?
As particle size increases, the permeability decreases.
As particle size increases, the permeability increases.
As permeability decreases, the particle size decreases.
As permeability increases, the particle size remains constant.
