Answers & Comments
Answer:
11. A.
Details Explanation: Our Moon doesn't have an atmosphere because it is too small and doesn't have a strong magnetic field. Any atmosphere might have had would be stripped away by the solar wind that barrages the small world. In contrast, our planet has more mass to hold its atmosphere close, and a strong magnetic field to protect it.
12. B.
Details Explanation: As the Earth is much larger than the Moon, the Moon's rotation is slowed down until it reaches a balance point. This means that the same portion of the Moon always faces towards the Earth, and we can never see the far side.
13. A.
Details Explanation: Only 1% of the surface of the far side is covered by maria, compared to 31.2% on the near side. On the Moon's perpetually Earth‐facing near side, on any given night, or day, one can observe dark and light patches with the naked eye.
14. A.
Details Explanation: For the first time, water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places.
15. C and D
Details Explanation: During a full or new moon, when the Earth, moon and sun align, spring tides form, creating higher and lower than normal tides. During the first and third-quarter moon phases, when the moon and sun are at right angles to the Earth, neap tides occur, creating low and high tides with minimal difference in heights.
16. A and B.
Details Explanation: Neap tides occur halfway between each new and full moon – at the first quarter and last quarter moon phase – when the sun and moon are at right angles as seen from Earth. Then the sun's gravity is working against the gravity of the moon, as the moon pulls on the sea.
17. wala pong pagpipiliian lagay ko nalang po details niya)
Details Explanation: the gravitational pull of the sun is 'added' to the gravitational pull of the moon on Earth, causing the oceans to bulge a bit more than usual. This means that high tides are higher and low tides are lower than average. These are called 'spring tides.
18. A.
Details Explanation: You can look at the Moon during any of its illuminated phases, but for better viewing of craters and mountains, try phases other than the full Moon. The shadows on the surface will be more pronounced, and help distinguish features you might otherwise miss.
19. A.
Details Explanation: The Moon that we see looks very dark. First Quarter: The right half of the Moon appears lighted and the left side of the Moon appears dark. ... This means that the Earth, Sun, and Moon are nearly in a straight line, with the Earth in the middle. The Moon that we see is very bright from the sunlight reflecting off it.
20. C.
Details Explanation: The giant-impact hypothesis is currently the favored scientific hypothesis for the formation of the Moon. Supporting evidence includes: Earth's spin and the Moon's orbit have similar orientations. The Earth–Moon system contains an anomalously high angular momentum.
Explanation: Hope it helps :)
