Question

if position 1 is a new moon & position 5 is a full moon, what would the moon look like from space in position 4? * 1 point

Explanation:

Step1: Analyze Moon Phases

Position 1 is new moon (Moon between Earth and Sun, dark side toward Earth). Position 5 is full moon (Earth between Moon and Sun, fully lit side toward Earth). Position 4: Moon is moving from full moon (position 5) toward next phases? Wait, no—orbital direction: from position 1 (new) to 2,3,4,5 (full). So position 4 is between position 3 and 5. Wait, new moon (1) → waxing crescent (2) → waxing gibbous (3) → almost full (4) → full (5). Wait, no, the diagram: Sun is on left, Earth center. Position 1: Moon between Earth and Sun (new, dark). Position 5: Moon opposite Sun (full, fully lit). So position 4: Moon is at a phase where most of the face toward Earth is lit, but not full. Wait, the options: A is half-lit (first quarter? No, new to full: waxing. Wait, position 4: when moving from new (1) to full (5), the phases are waxing crescent (2), waxing gibbous (3), then near full (4). Wait, but the two images: A is half-dark (like first quarter? No, new moon (1) is dark. Full moon (5) is full light. So position 4: the Moon's phase should be mostly lit, like option B? Wait, no—wait, the orbital path: from 1 (new, Sun-Earth-Moon? No, new moon is Moon between Sun and Earth (Sun→Moon→Earth), so Moon's dark side toward Earth. Full moon is Earth between Sun and Moon (Sun→Earth→Moon), so Moon's lit side toward Earth. So positions: 1: Sun-Moon-Earth (new, dark). 5: Sun-Earth-Moon (full, lit). So moving from 1 to 5 (clockwise? The diagram: positions 1,2,3,4,5 around Earth. So 1 (left of Earth, near Sun), 2 (below 1), 3 (below Earth), 4 (right of Earth, below 5), 5 (right of Earth, opposite Sun). So position 4: Moon is at a position where Earth is between Sun and Moon? No, position 5 is full (Earth between Sun and Moon). So position 4 is before full (5), so the Moon's phase is waxing gibbous, almost full. So the image B is mostly lit, A is half-lit (like first quarter, but that's at 90 degrees). Wait, maybe I got the direction wrong. Alternatively, the Moon's orbit: from position 1 (new) to 5 (full) is a counterclockwise orbit? No, in the diagram, Sun is left, Earth center. So position 1: left of Earth (Moon between Sun and Earth: new). Position 5: right of Earth (Earth between Sun and Moon: full). So the Moon moves from 1 (left) to 2 (bottom-left), 3 (bottom), 4 (bottom-right), 5 (right). So the phase at position 4: when moving from new (1) to full (5), the illuminated portion toward Earth increases. So position 4: the Moon's face toward Earth is mostly lit, like option B (the right image, which is mostly white, lit). Option A is half-dark (like a first quarter, but that's at 90 degrees, but position 4 is closer to full. Wait, maybe the answer is B? Wait, no—wait, new moon (1) is dark, full (5) is full light. So position 4: the Moon's phase should be almost full, so the image B (mostly lit) is correct. Wait, but the two options: A is half-lit (like a crescent? No, A is half-dark, half-light. B is mostly light. So position 4: since 5 is full, 4 is just before full, so the phase is waxing gibbous, which is mostly lit, so option B. Wait, but maybe I messed up. Alternatively, the key: new moon (1) → full moon (5) is 14 days. So position 4 is 4 steps from 1, 1 step from 5. So phase at 4: almost full, so the Moon looks mostly lit, like option B. So the correct answer is B? Wait, no—wait the options: A is the left image (half-dark), B is right (mostly lit). So position 4: the Moon's phase is near full, so B.

Step2: Confirm Phase

New moon (1): Moon between Sun and Earth → dark side toward Earth. Full moon (5): Moon opposite Sun → lit side toward Earth. Position 4: Moon is at a position where most of the face toward Earth is lit (since it's close to full moon at 5). So the image B (mostly lit) matches this phase. Option A is half-lit (like a first quarter, but that's at 90 degrees from new, which would be position 3? No, position 3 is below Earth. Wait, maybe the orbital direction is counterclockwise. Anyway, the logic: new (1) → full (5), so position 4 is near full, so mostly lit, so option B.

Answer:

B (the right image, or the option labeled B)
