The figure shows the path of a planet orbiting the Sun. The three areas shaded in gray have equal areas?
The time intervals from A to B, C to D, and E to F are all equal.
The time interval from A to B is twice the interval from E to F.
The time intervals from A to B, C to D, and E to F combine to be equal to one half of a full orbit.
The time intervals from C to D and from E to F combine to be equal to the time interval from A to B.
Why has only one-half of the Moon ever been observed from Earth?
The Moon does not rotate on its axis.
The Moon is not visible during the day.
The Moon has phases that coincide with its rate of rotation.
The Moon rotates at the same rate that it revolves around Earth.
Which is true about the way sunlight changes from winter to summer?
Sunlight travels faster in summer.
Sunlight is more intense in summer.
Sunlight has higher wavelengths in summer.
Sunlight has greater frequencies in summer
Earth travels on an elliptical orbit around the Sun
When Earth is at the point labeled on the diagram, it moves most quickly in its orbit. Which BEST explains this more rapid motion of Earth?
The amount of solar heat reaching Earth is greatest at this point
The Sun’s gravitational pull on Earth is strongest at this point.
Earth is closest to the Sun’s magnetic field at this point.
Earth is closest to the Sun’s radioactivity at this point.
A very large pendulum can be used to investigate motion and forces on a planetary scale. When the pendulum is first set in motion, it will swing back and forth along the same line of swing. After a few hours, the line of the swing of the pendulum will change direction. What MOST likely affects the line of swing of the pendulum?
the rotation of Earth on its axis
the revolution of Earth around the Sun
the gravitational pull of the Sun on Earth
the gravitational pull of the Moon on Earth

Seafloor spreading occurs at divergent boundaries. Which statement BEST identifies the geologic process taking place at the point where seafloor spreading occurs?
a trench is forming
new crust is forming
oceanic crust is subducting
a continental plate is subducting
Which will most likely form when movement along a plate boundary forces a landmass to be pulled apart?
Volcanic island arc

continental rift
oceanic trench
Assuming the layers have NOT been disturbed, which layer would contain the MOST crystallized minerals?
w
x
y
z
Bedrock that is closer to oceanic ridges is younger in age than bedrock that is farther away. What can best be concluded from this information?
The shape of Earth’s lithosphere is continually changing.
The movement of continental plates is caused by volcanic eruptions.
The oceans are becoming deeper and warmer as more rocks are produced.
The rocks on the ocean floor are producing tectonic plates that are converging.
Which is the BEST evidence that rocks found deep underground were once exposed at the surface?
The rocks have been melted by a magma.
The rocks have been broken by faults.
The rocks have been weathered by water.
The rocks have been folded by pressure
How can urbanization affect a local area?
It can decrease the risk of water pollution in an area
It can increase the risk of flooding in an area.
It can decrease the need for natural resources in an area.
It can increase the number of invasive species in an area.
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 irrigation
use of fertilizers
use of machinery
Paleoclimatologists study the climate and its changes throughout Earth’s history. What observation by paleoclimatologists led scientists to predict that the average temperature of the planet is rising due to the combustion of fossil fuels?
direct correlation between atmospheric carbon dioxide level and global temperature
changes in sea level that correspond to average global temperature
increases in average temperatures with increasing volcanic activity
a recent rise in global temperature as atmospheric pollution increased
Chemical weathering occurs when minerals in rocks are changed chemically. Which of these will MOST likely change the rate of chemical weathering on a rock?
decrease in air temperature
increase in rainfall amounts
slow movement of a glacier
rapid growth of plant roots
Water, wind, ice, gravity, and waves are the primary agents of erosion that wear away at the surface of Earth. Which picture shows an area that would be MOST affected by erosion?
image 1
image 2
image 3
image 4
Nuclear power and drilling for oil can both negatively affect ecosystems. Which negative impact can only be caused by nuclear power?
air pollution
water contamination
exposure to uranium
spread of invasive vegetation
