Final Review Part 5

Which causes a subduction zone?

• The formation of mountains because of the uplifting of a continental plate

• The collision of an oceanic plate with a continental plate

• An earthquake beneath the ocean floor

• The eruption of a volcano

Which activity is most likely to create ocean islands far from continents or tectonic plate boundaries?

• Deposition

• Erosion

• Sedimentation

• Hot spots

How does Earth’s magnetic field protect life on Earth?

• By deflecting solar winds

• By reducing greenhouse gases

• By absorbing chlorofluorocarbons

• By absorbing visible light wavelengths

How does the sun make life possible on Earth?

• It provides the energy needed for photosynthesis

• It produces the gases found in the atmosphere

• It causes the core of Earth to produce heat energy

• It causes deep ocean currents to circulate around the globe

Which statement best explains how the sun’s energy is transferred through the vacuum of space to warm Earth?

• The sun’s energy moves from particle to particle by conduction

• The sun’s energy moves like a fluid from the sun to Earth by convection

• The sun’s energy moves through space using both conduction and convection

• The sun’s energy moves through space by electromagnetic waves called radiation

How does the sun produce energy used to warm Earth?

• The sun undergoes nuclear fission, producing helium from the splitting of hydrogen, and releasing energy

• The sun undergoes nuclear fission, producing hydrogen from the splitting of helium, and releasing energy

• The sun undergoes nuclear fusion, producing helium from the combining of hydrogen, and releasing energy

• The sun undergoes nuclear fusion, producing hydrogen from the combining of helium, and producing energy

What would result if Earth were no longer tilted on its axis?

• There would be no tides in our oceans

• The four seasons would no longer exist

• The day would be longer and the night shorter

• The distance between the Sun and Earth would increase

What causes the sun’s rays to hit different latitudes of Earth at different angles, resulting in seasons?

• The rotation of Earth on its axis during its elliptical orbit

• The tilt of Earth’s axis as it revolves around the sun

• The spherical shape of Earth as it revolves around the sun

• The distance of Earth from the sun during its elliptical orbit

When she spends a full day at the beach, Mary notice that the water level is constantly changing. How could this be explained?

• The tilt of Earth affects the density of the water

• The revolution of Earth around the sun affects the tides

• The rotation of Earth changes the amount of water in the ocean

• The gravitational interaction between the moon and Earth affects the tides

What causes Earth’s equator to be slightly bulged in shape?

• Nutation

• Revolution

• Rotation

• Barycenter
