End of Year Earth Science Part 2

Front

Which statement describes the motion of Earth around the sun? Options: The speed of Earth is constant regardless of its distance from the sun., The speed of Earth is constant because the distance remains the same between Earth and the sun., Speed increases the farther Earth is from the sun and decreases the closer it is to the sun., Speed increases the closer Earth is to the sun and decreases the farther it is from the sun.

Back

Speed increases the closer Earth is to the sun and decreases the farther it is from the sun.

Scientists are studying a graph showing the time differences between the seismic P-waves and the seismic S-waves as they travel through Earth. What information can they learn from the graph? Options: the magnitude of an earthquake, the duration of an earthquake, the epicenter of an earthquake, the intensity of an earthquake

Back

the epicenter of an earthquake

Front

Which agent of erosion leads to the formation of sand dunes? Options: ice, wind, water, gravity

Back

wind

Front

How can water be an agent for physical weathering?

Back

by seeping into the cracks of rocks and freezing

Front

Which is most likely a prevention strategy for flooding? Options: building artificial levees, reducing water consumption, recycling bottled-water containers, building waste landfills for metals and other contaminants

Back

building artificial levees

Front

What describes a disadvantage of adding large quantities of sand to the beach to stabilize the shoreline? Options: It causes inland erosion., It is a short-term solution., It creates a barrier that prevents the tides from occurring along the coastline., It creates a wall that disrupts the vegetation along the coastline.

Back

It is a short-term solution.

Front

Which results from the unequal heating of the ocean water of Earth?

Back

changes in ocean current patterns

Front

Why are ocean currents important to coastal regions?

Back

They can warm or cool the air temperatures along coastal regions.

Front

Which best describes the relationship between carrying capacity and Earth’s resources? Options: A population that is below the carrying capacity will have an increase in contagious diseases., A population that is above the carrying capacity will have a decrease in natural resources., A population that is below the carrying capacity will experience a decrease in freshwater resources., A population that is above the carrying capacity will experience an increase in plant production.

Back

A population that is above the carrying capacity will have a decrease in natural resources.

Front

How could the exponential growth of the human population impact regions throughout the world?

Back

It could lead to an increase in the demand for food in the regions.
