Unit 5 Review Earth-Sun-Moon

The revolution of the Earth causes:

• Seasons
• Years
• Days
• Months

The rotation of the Earth causes:

• Seasons
• Years
• Days
• Months

Why is a new moon not visible in the sky?

• No sunlight is reflected off the moon
• Sunlight is reflected off only a small portion   of the moon.
• The moon is on the opposite side of the Earth from the Sun.
• The moon is positioned between the Earth and the Sun

Which of the following statements is correct?

• The moon rotates around the Earth, and the Earth rotates around the Sun.
• The moon revolves around the Earth, and the Earth revolves around the Sun.
• The Earth rotates around the moon, and the moon rotates around the Sun.
• The Earth revolves around the moon, and the moon revolves around the Sun.

The Moon is visible to us on Earth because it:

• emits (gives off) its own light.
• reflects light from Earth.
• reflects light from the stars.
• reflects light from the Sun.

Which statement best explains why there are seasons on Earth?

• Earth’s axial tilt remains fixed as it revolves around the sun.
• Earth’s orbit is slightly elliptical, causing the distance from the sun to change.
• Clouds are more frequent during the winter months.
• Earth’s axial tilt changes as it revolves around the sun.

Which statement best describes Earth’s position during summer in the northern hemisphere?

• Earth is at its closest point to the Sun.
• Earth’s hemispheres receive equal amounts of solar energy.
• The north end of the Earth’s rotational axis leans toward the Sun.
• The Sun emits (gives off) a greater amount of light and heat.

During a solar eclipse:

• the moon is directly between Earth and the sun.
• Earth is directly between the moon and the sun.
• the moon is at a 90° angle with respect to the sun and Earth.
• the sun is blocked by Earth’s shadow.

Which event closely coincides with one month?

• The period of Earth’s revolution
• The lunar cycle
• The period of the Earth’s rotation
• The tilt of Earth’s axis

The moon’s gravitational force has a greater tide-causing effect than the sun’s gravitational force. What is one reason for this?

• The moon orbits Earth, and the sun does not move.
• The sun has a greater mass than the moon.
• The moon is much closer to Earth than the sun.
• Water can be distorted by the moon’s gravitational force but not by the sun’s gravitational force.
