Unit 6: The Earth Quiz

What is the longest day of the year?

• 
  fall equinox

• spring equinox

• summer solstice

• winter solstice

What season is it in the Northern Hemisphere in the picture?

•  

  summer

  The model shows the Northern Hemisphere tilted away from the Sun. Winter is the season that occurs when the Northern Hemisphere receives the least amount of direct sunlight.

• spring

  The model shows the Northern Hemisphere tilted away from the Sun. Winter is the season that occurs when the Northern Hemisphere receives the least amount of direct sunlight

• winter

  The Northern Hemisphere is tilted away from the Sun so it is receiving the least amount of direct sunlight and experiencing winter.

• autumn

  The model shows the Northern Hemisphere tilted away from the Sun. Winter is the season that occurs when the Northern Hemisphere receives the least amount of direct sunlight.

Which of the following statements best describes how Earth's movement and tilt affects its periods of daylight and seasons?

•  

  Earth's rotation produces unequal periods of daylight and climate patterns called seasons.

• Earth's revolution and its tilt produce unequal periods of daylight and climate patterns called seasons.

• Earth's rotation and its tilt produce unequal periods of daylight and climate patterns called seasons.

• Earth's tilt produces unequal periods of daylight and climate patterns called seasons.

Which relationship between Earth and the Sun explains the changing of the seasons during a year?

• Yearly increases in solar activity cause summer, and decreases in solar activity cause winter.

• During a year, the Sun expands to cause summer, and then contracts to cause winter.

• As Earth travels closer to the Sun, summer occurs, and as it gets further away, winter occurs.

• The tilt of Earth's axis causes changes in the angle of the Sun's rays during a year.

The diagram shows Earth in its yearly orbit around the Sun. During the year, places in the Northern and Southern Hemispheres experience seasons because of the tilt of Earth on its axis.

Which statement correctly identifies the season in the Northern Hemisphere when the Earth is at Position B?

• It is summer because the northern part of Earth is tilted toward the Sun.

• It is winter because Earth is farther away from the Sun.

• It is winter because the northern part of Earth tilts away from the Sun.

• It is summer because Earth is farther away from the Sun.

What do the arrows around X show?

•  

  the Moon's monthly orbit around the Sun

• Earth's monthly rotation on its axis

• Earth's daily rotation on its axis

•  

  the Moon's daily orbit around Earth

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

• 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.

• 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.

• 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.

• 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.

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

• autumn equinox

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

• summer solstice

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

• vernal equinox

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

• winter solstice

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

When Earth's Northern Hemisphere is tilted toward the Sun, the Southern Hemisphere is tilted away from the Sun. What is the difference between these two hemispheres during this time?

• The Northern Hemisphere is experiencing winter, while the Southern Hemisphere is experiencing summer.

• The Northern Hemisphere has 24 hours of daylight, while the Southern Hemisphere has 24 hours of darkness.

• The Northern Hemisphere has longer days and shorter nights, while the Southern Hemisphere has shorter days and longer nights.

• The Northern Hemisphere is receiving less solar energy, while the Southern Hemisphere is receiving more solar energy.
