There would be no occurrence of different seasons.
Intensity of sunlight would be the same in all places.
Days would be longer than nights all through the year.
There would be no changing of the phases of the moon.
Which percentage of the solar energy that comes to Earth is transformed by photosynthesis
into another form of energy?
0.023%
1.23%
12.3%
23%
Convection currents in the mantle are a driving force of tectonic movement. At which
location do the convection currents cause the plates to diverge?
strike-slip fault
subduction zone
mid-ocean ridges
folded mountains
Weathering and erosion help to shape the surface of Earth. Which BEST represents an example of weathering?
Flowing water transports rocks to the ocean.
Pieces of rock pile on top of each other in layers.
Wind and rain break large rocks into smaller pieces.
Wind blows small pieces of rock from one area to another.
Which of the following is a likely reason for a sinkhole to form?
the removal of underground resources
a collision between two tectonic plates
dense rock formations under the topsoil
buildup of sediment on the ocean floor
Soil erosion can be BEST prevented by
removing grass from the steepest slope.
building terraces into the sides of a slope.
heavily watering the vegetation on the slope.
increasing the slope of the land by adding more soil.
The Dust Bowl was a series of dust storms in the United States and Canada in the 1930s. The dust storms were the result of a widespread drought that followed decades of poor farming practices where the soil was depleted and left barren. Which farming practice MOST likely was introduced as a result of the Dust Bowl?
crop rotation
crop irritation
use of fertilizers
use of machinery
All energy resources have benefits, risks, and drawbacks. Which two resources present the MOST dangerous risks and consequences for the environment during their acquisition?
oil and coal
coal and solar energy
geothermal energy and oil
solar energy and geothermal energy
Because water can hold a large amount of heat, which effect do oceans have on nearby land areas?
They prevent rapid extreme temperature changes.
They form high-pressure areas that cause magma currents.
They provide the energy that triggers volcanic events.
They lower the freezing point of fresh water.
Which is the best way to conserve worldwide freshwater resources?
build more roads and highways for cars and trucks
increase the amount of land used to raise cattle
develop more modern coal-powered plants
use more efficient irrigation techniques
