Short Answers (Sample Responses)

  1. A lunar eclipse occurs when the Earth is directly between the Sun and the Moon, causing the Earth's shadow to fall on the Moon. This can only happen during a full moon.

  2. A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking the Sun's light. A lunar eclipse happens when the Earth comes between the Sun and the Moon, causing the Earth's shadow to cover the Moon.

  3. The Goldilocks Zone, or habitable zone, is the region around a star where conditions are just right for liquid water to exist on a planet’s surface—crucial for life as we know it.

  4. The gravitational pull of the Moon (and to a lesser extent, the Sun) creates bulges in the Earth's oceans, leading to high and low tides.

  5. A sidereal month is the time it takes the Moon to complete one orbit around the Earth relative to the stars (about 27.3 days), while a synodic month is the time it takes for the Moon to go from one new moon to the next (about 29.5 days), accounting for the Earth's movement around the Sun.

  6. For an eclipse to happen, the Sun, Earth, and Moon must be aligned in a straight line and properly positioned; otherwise, the shadow will not fall on the respective bodies.
