Question 10

The graph shows the total number of hurricanes that have reached the coasts of the United States between 1851 and 2015.

A student predicts that the hurricane data for South America should show the same pattern. Which statement BEST describes why the student is correct or incorrect?

Accepted Answer

The student is incorrect because the Southern Hemisphere is warmest in January and February.

This is the result of correctly reasoning that, because hurricanes are formed by moisture evaporating from bodies of water, and because evaporation increases at higher temperatures, the Southern Hemisphere will experience the greatest number of hurricanes during the warmer months. Therefore, the graph will show the opposite pattern as the one shown.

Answer

The student is correct because hurricanes are more likely to form during warmer months.

This is the result of correctly understanding the relationship between temperature and hurricane formation while ignoring that the warmest months differ in the Southern Hemisphere.

Answer

The student is incorrect because hurricanes are more likely to form in the Northern Hemisphere.

This is the result of incorrectly understanding the factors influencing hurricane formation. Hurricanes are equally likely to form in the Northern and Southern Hemispheres.

Answer

The student is correct because more water evaporates from the oceans in August and September.

This is the result of correctly understanding the relationship between evaporation and hurricane formation but neglecting to understand that the greatest amount of evaporation occurs during the warmest months in the Southern Hemisphere.

Question 11

Question 13

Tornadoes form in places where large disturbances exist in the atmosphere. Note the conditions present in the figure below.

What response identifies the likeliest location in the image where a tornado would form?

Accepted Answer

A tornado would most likely form where the Continental Polar and Maritime Tropical air masses meet. Tornadoes form when warm, moist air collides with cold, dry air.

This answer is the result of the correct identification of the location where a tornado would most likely form and a correct description of the conditions that encourage tornado formation.

Answer

A tornado would most likely form where the Continental Polar and Continental Tropical air masses meet. Tornadoes form when hot, dry air collides with cold, dry air.

This answer is the result of an incorrect identification of the location where a tornado would most likely form and an incorrect description of the conditions that encourage tornado formation. Warm and moist, not hot and dry, air is needed to interact with a cold, dry air mass for a tornado to form.

Answer

A tornado would most likely form where the Maritime Polar and Maritime Tropical air masses meet. Tornadoes form when warm, moist air meets cool, moist air.

This answer is the result of an incorrect identification of the location where a tornado would most likely form and an incorrect description of the conditions that encourage tornado formation. Cool, dry air, not cool, moist air, is needed to interact with warm, moist air to form a tornado.

Answer

A tornado would most likely form where the Continental Polar and Maritime Polar air masses meet. Tornadoes form when very cold, dry air meets cool, moist air.

This answer is the result of an incorrect identification of the location where a tornado would most likely form and an incorrect description of the conditions that encourage tornado formation. Warm, moist air must interact with cool, dry air for a tornado to form.

Question 14

The graph below shows some information about Earth's atmospheric layers.

If the stratosphere did not contain the ozone layer shown, which prediction could BEST be made about Earth's atmosphere?

Accepted Answer

The troposphere would have lower temperatures since there would be no ozone layer to trap heat near Earth's surface.

One function of the ozone layer is that it traps warm air near Earth's surface (along with its function of blocking entry of dangerous UV rays).

Answer

The troposphere would remain the same temperature since the ozone layer's function is to block out incoming ultraviolet rays and not to regulate temperature.

The ozone layer does trap some heat near Earth's surface, so the troposphere would likely experience a decrease in temperatures if the ozone layer did not exist.

Answer

The troposphere would experience large temperature extremes each year as the seasons changed since there would be no ozone to regulate seasons.

If no ozone layer was present, the resulting change in temperatures in the troposphere would likely be relatively constant (in a decreasing direction) as opposed to resulting in seasonal fluctuations.

Answer

The troposphere would have higher temperatures since the lack of an ozone layer would allow Earth's surface to receive warmer air from the mesosphere.

The ozone layer helps warm Earth's surface by trapping heat, so lacking an ozone layer would likely reduce temperatures on Earth. Also, the mesosphere is colder than the troposphere, making it unlikely to warm Earth's surface.

Question 15

The moon was created about 4.5 billion years ago when an object the size of Mars crashed into Earth. The crash threw rocks, debris, and dirt into space and these materials came together to form the moon. What would most likely happen if the moon was smaller than it is now?

Accepted Answer

The tides would be smaller because the gravitational pull between the Moon and Earth would be smaller.

Answer

The tides would be bigger because the gravitational pull between the Moon and Earth would be smaller.

Answer

The tides would be smaller because the gravitational pull between the Moon and Earth would be bigger.

Answer

The tides would be bigger because the gravitational pull between the Moon and Earth would be bigger.

Question 16

The graph below shows the average monthly temperatures for an inland city verse a coastal city.

What is one explanation for the differences in the temperatures between the two cities?

Accepted Answer

Large bodies of water absorb and release heat very slowly and moderate the temperature.

Answer

Fewer people live in the coastal city.

Answer

The inland city has more buildings than the coastal city.

Answer

Large bodies of water get very hot in the summer and very cold in the winter.

Question 17

Eric stood on the sidewalk and watched as sandhill cranes flew by overhead. He noticed that the concrete areas of the sidewalk were hotter to walk on than the grass areas. He also noticed many cranes circling upwards to gain height, and then coasting downwards again. His friend told him that birds do this to use wind patterns to save energy. These wind patterns are caused by the way different parts of the Earth's surface are heated differently by the Sun. Which of the following models best explains one way these wind patterns are formed?

Accepted Answer
