11.

Two locations experience opposite seasons. During January, City X experiences winter, and City Z experiences summer. Which statement best describes the locations of each city?

a)

A.  City X and City Z are in a hemisphere that is tilted toward the Sun.

The cities experience opposite seasons during the same month, so they are most likely located in different hemispheres, not the same hemisphere.

b)

B. City X and City Z are in a hemisphere that is tilted away from the Sun.

The cities experience opposite seasons during the same month, so they are most likely located in different hemispheres, not the same hemisphere.

c)

C. City X is in a hemisphere that is tilted toward the Sun, and City Z is in a hemisphere that is tilted away from the Sun.

City X is located in a hemisphere that is tilted away from, not toward, the Sun, and City Z is located located in a hemisphere that is tilted toward, not away from, the Sun.

d)

D. City X is in a hemisphere that is tilted away from the Sun, and City Z is in a hemisphere that is tilted toward the Sun.

City X is experiencing winter, so it must be located in a hemisphere that is tilted away from the Sun, receiving less direct sunlight. City Z is experiencing summer, so it must be located in a hemisphere that is tilted toward the Sun, receiving more direct sunlight.

12.

Earth revolves around the Sun on its tilted axis. As Earth revolves around the Sun, different parts of Earth receive different amounts of sunlight. What effect does this have on Earth?

a)

A. Day and night

Earth rotating on its axis, not receiving different amounts of sunlight, causes day and night.

b)

B. different seasons

Earth receiving different amounts of sunlight causes seasons.

c)

C. high and low tides

The Moon revolving around Earth causes tides. Earth receiving different amounts of sunlight causes seasons.

d)

D. constant temperatures

Earth receiving different amounts of sunlight causes different seasons, not consistent temperatures.

13.

In July, the Northern Hemisphere receives more direct sunlight than the Southern Hemisphere. Why does one hemisphere receive more direct sunlight than the other?

a)

A. Earth is tilted on its axis.

Because Earth is tilted on its axis, the hemisphere that is tilted toward the Sun receives more direct sunlight than the hemisphere that is tilted away from the Sun.

b)

B. Earth rotates on its axis.

Earth's rotation on its axis causes day and night, not one hemisphere to receive more direct sunlight than the other.

c)

C. Earth revolves around the Sun.

Earth's revolution causes seasons to change; it is not the reason that one hemisphere experiences different amounts of direct sunlight.

d)

D. The Moon revolves around Earth.

The Moon's revolution around Earth causes tides on Earth, not one hemisphere to receive more direct sunlight than the other.

14.

What would most likely occur if the Sun did not heat Earth?

b)

B. There would be slightly less weather.

c)

15.

Read the passage about Hadley. Hadley and her parents live in Georgia and are planning a vacation to Maine for spring break. Why would Hadley's mom tell her to pack warm clothing for a spring time trip north to Maine?

a)

A. Because Maine is farther north in the Northern Hemisphere and gets less direct sunlight, it will be colder than Georgia.

b)

B. Because Maine is farther north in the Northern Hemisphere and gets more direct sunlight, it will be colder than Georgia.

c)

C. Because Maine is farther north in the Northern Hemisphere and gets less direct sunlight, it will be warmer than Georgia.

d)

D. Because Maine is farther north in the Northern Hemisphere and gets more direct sunlight, it will be warmer than Georgia.

16.

At what time of year does the Southern Hemisphere receive the minimum hours of daylight?

a)

A. autumn equinox

During an autumn equinox, the Southern Hemisphere receives more hours of daylight than a winter solstice.

b)

B. summer solstice

During a summer solstice, the Southern Hemisphere receives the maximum, not minimum, hours of daylight.

c)

C. vernal equinox

During a vernal equinox, the Southern Hemisphere receives more hours of daylight than a winter solstice.

d)

D. winter solstice

During a winter solstice, the Southern Hemisphere is tilted away from the Sun and receives the least hours of daylight.

17.

During winter, the angle at which sunlight reaches New York is less than the angle at which sunlight reaches Florida. How does the angle of sunlight that each place receives affect how winter is experienced in each place?

a)

A. Florida receives more indirect sunlight than New York, so Florida is colder than New York.

Florida is warmer, not colder, than New York during winter because it receives more direct, not indirect, sunlight than New York.

b)

B. Florida receives more indirect sunlight than New York, so Florida is warmer than New York.

Florida is warmer than New York during winter because it receives more direct, not indirect, sunlight than New York.

c)

C. Florida receives more direct sunlight than New York, so Florida is colder than New York.

Florida is warmer, not colder, than New York during winter because it receives more direct sunlight.

d)

D. Florida receives more direct sunlight than New York, so Florida is warmer than New York.

Florida is warmer than New York during winter because it receives more direct sunlight than New York.

18.
  1. Solar eclipses occur about twice a year. But seeing a total solar eclipse is often described as a "once in a lifetime" experience. Why is it so rare to experience a total solar eclipse?

a)

Total solar eclipses only occur once or twice a century.

b)

Total solar eclipses usually occur in late winter, when clouds are most likely to block the view.

c)
  • The width of the Moon's shadow is very narrow, so a particular area is very unlikely to lie along the path of totality during the eclipse.
