Why has only one-half of the Moon ever been observed from Earth?

• The Moon does not rotate on its axis.
• The Moon is not visible during the day.
• The Moon has phases that coincide with its rate of rotation.
• The Moon rotates at the same rate that it revolves around Earth.

The length of time between night and day on Earth varies throughout the year. This time variance is explained primarily by

• the position of the Sun.
• the position of the Moon.
• Earth’s angle of tilt
• Earth’s distance from the Sun

The temperate zones of the United States experience changing of seasons from winter to summer. Which is the reason for this annual change of seasons?

• the rotation of Earth on its axis
• the tilt of Earth’s axis of rotation
• the distance of Earth from the Sun
• the size and orbit of the Moon around Earth

Earth travels on an elliptical orbit around the Sun. When Earth is at the point labeled on the diagram, it moves most quickly in its orbit. Which BEST explains this more rapid motion of Earth?

• The amount of solar heat reaching Earth is greatest at this point.
• The Sun’s gravitational pull on Earth is strongest at this point.
• Earth is closest to the Sun’s magnetic field at this point.
• Earth is closest to the Sun’s radioactivity at this point.

The diagram shows the difference in sunlight reaching Earth at Points 1 and 2. Based on the diagram, what is another difference between Points 1 and 2?

• Tides will be higher at Point 2 than at Point 1.
• The pull from gravity will be greater at Point 2 than at Point 1.
• Each day is slightly longer than 24 hours at Point 1 and slightly shorter at Point 2.
• The region at Point 1 is experiencing summer while the region at Point 2 is experiencing winter.

Earth’s spherical shape results in an uneven distribution of sunlight reaching Earth’s surface. This uneven distribution is MOST directly responsible for differences in which climatic variable at different latitudes on Earth’s surface?

• wind speed
• temperature
• annual rainfall
• average humidity

• eclipses
• length of year
• change of seasons
