A) full moon B) new moon C) waxing gibbous D) waning crescent 5.
A) During an equinox, the northern hemisphere is tilted closer to the Sun. B) During an equinox, the southern hemisphere is tilted closer to the Sun. C) During the rest of the days of the year, Earth is tilted, and each hemisphere experiences opposite seasons. D) During an equinox, the seasons switch, and instead of occurring at the same time, they occur opposite each other. 6.
A) Earth's axis is the imaginary line around which Earth spins. B) Earth's axis is the imaginary vertical line that separates the eastern and western hemispheres. C) Earth's axis is the imaginary horizontal line that separates the northern and southern hemispheres. D) Earth's axis is the imaginary line around which Earth spins around the Sun. 7.
A) Earth, the Sun's B) the Moon, Earth's C) Earth, the Moon's D) the Sun, Earth's 8.
A) ten B) eight C) seven D) five 9.
A) eclipses B) day and night C) the seasons D) a year 10.
A) They believe the movement of material inside Earth's core generates a magnetic field. B) They believe Earth's tilted axis along with Earth's rotation generates a magnetic field. C) They believe the movement of material inside Earth's core along with Earth's rotation generates a magnetic field. D) They believe the Earth's revolution around the Sun generates a magnetic field. 11.
A) The change in distance occurs at the same time as the seasons, so we don't notice the change. B) The change in distance is the real cause of seasons on Earth. C) The change in distance is actually minimal. Earth's tilted axis is the real cause of seasons on Earth. D) Even though Earth's orbit is an ellipse, the change in distance from the Sun is only an optical illusion. 12.
A) the penumbra B) the upper mantle C) the umbra D) a moon spot 13.
A) Earth's orbit is a circle, so the distance sometimes changes. B) Earth's orbit is an ellipse - an elongated, closed curve - but the change in distance from the Sun is only an optical illusion. C) Earth's orbit is a circle, so the distance never changes. D) Earth's orbit is an ellipse - an elongated, closed curve - so the distance sometimes changes. 14.
A) because the motion of the Moon's revolution around Earth and its rotation on its axis take the same amount of time B) because the motion of Earth's revolution around the Sun and its rotation on its axis take the same amount of time C) because the motion of Earth's revolution around the Sun and the Moon's rotation on its axis take the same amount of time D) because the motion of the Sun through the solar system and Earth's rotation on its axis take the same amount of time. 15.
A) the point at which the Sun is closest to Earth B) the point at which the Sun reaches its greatest distance north or south of the equator C) the point at which the Sun reaches its greatest distance east or west of the prime meridian D) the seasons 16.
A) waxing crescent B) a lunar eclipse C) third quarter moon D) a solar eclipse 17.
A) waxing crescent B) waning crescent C) waxing gibbous D) new moon 18.
A) the capture theory B) the theory that Earth ejected a blob of molten material that formed the Moon C) the impact theory D) the theory that loose material around Earth condensed to produce the Moon 19.
A) waning crescent B) waning gibbous C) new moon D) waxing gibbous 20.
A) Rotation refers to Earth's spinning on its axis, and revolution refers to Earth's spinning around the Sun. B) Rotation refers to Earth's spinning on its equator, and revolution refers to Earth's spinning around the solar system. C) Revolution refers to Earth's spinning on its axis, and rotation refers to Earth's changing seasons. D) Revolution refers to Earth's spinning on its axis, and rotation refers to Earth's spinning around the Sun.
