Question 1

Two transverse waves travel through the same medium. Wave X has a much larger amplitude than Wave Y, but both waves have the same wavelength. How does the energy of Wave X compare to the energy of Wave Y?

Wave X carries more energy because it has a larger amplitude. Wave X carries less energy because amplitude does not affect energy. Both waves carry the same energy because they share the same wavelength. Both waves carry the same energy because amplitude does not matter.

Correct Answer:

Wave X carries more energy because it has a larger amplitude.

Question 2

A region was covered by a shallow sea millions of years ago, where huge numbers of tiny marine organisms lived, died, and were buried under sediment. Today this region has large deposits of oil and natural gas. Which best explains this?

The buried remains of marine organisms were transformed into fossil fuels by heat and pressure over millions of years. The shallow sea evaporated and left behind oil and natural gas as minerals. Volcanic activity beneath the sea produced the oil and natural gas directly. The ocean water itself slowly turned into oil and natural gas as it cooled.

Correct Answer:

The buried remains of marine organisms were transformed into fossil fuels by heat and pressure over millions of years.

Question 3

Students designed several sets of stairs, all 100 cm tall, to help a small dog climb onto a sofa. The most important purpose is that the dog can safely climb each step. Which criterion is MOST important for evaluating the designs?

having a small enough height between steps for the dog to climb being made from the lightest possible material being able to hold the greatest possible mass being built from the strongest available material

Correct Answer:

having a small enough height between steps for the dog to climb

Question 4

A cold, dry air mass moves toward a warm, moist air mass over a city. As the dense cold air pushes under the warm air, the warm air is forced upward. What will most likely happen to the weather in the city?

The air will become cooler and the skies will become cloudy as the lifted warm air condenses. The air will become warmer and the skies will become clear. The air will become cooler and the skies will become clear. The air will become warmer and the skies will become cloudy.

Correct Answer:

The air will become cooler and the skies will become cloudy as the lifted warm air condenses.

Question 5

In a Canadian forest food web, both the Canada lynx and the red fox hunt and eat the snowshoe hare. Which best describes the relationship between the lynx and the fox?

competition, because they use the same food resource predation, because one feeds on the other mutualism, because both benefit from the relationship parasitism, because one lives off the other

Correct Answer:

competition, because they use the same food resource
