Phases Eclipses And Tides Worksheet - Fill Online, Printable ... - Free Printable

It looks like you've uploaded a page from a math worksheet titled "Earth, Moon, and Sun – 12.3 Review and Reinforce: Phases, Eclipses, and Tides", which focuses on understanding Moon phases, eclipses, and tides.

Since I can't view images directly, I’ll help you solve the problems based on the text you provided. Below is the full solution to each question with explanations:

Understanding Moon Phases

> Use vocabulary from the lesson (new moon, first quarter, full moon, last quarter) to identify the phase of the Moon in each picture.

This section likely includes diagrams of the Moon’s phases. Since we don’t have the images, I'll explain how to identify them:

- New Moon: The Moon is between Earth and the Sun; the side facing Earth is not illuminated.
- First Quarter: Half of the Moon is lit (right side in the Northern Hemisphere).
- Full Moon: The entire face of the Moon is illuminated.
- Last Quarter: Half of the Moon is lit (left side in the Northern Hemisphere).

👉 *Answer depends on the image, but this is how you'd identify each.*

1. What phase of the Moon would someone on Earth see when the Moon is at position A (diagram)?

Assuming position A shows the Moon between Earth and Sun:
- ✔ Answer: New Moon
- Explanation: The Moon's dark side faces Earth, so it appears dark or invisible.

2. What phase of the Moon would someone on Earth see when the Moon is at position B, C, D, and E?

Let’s assume positions go around the orbit:

- B: After new moon → Waxing Crescent
- C: At right angle → First Quarter
- D: Opposite Sun → Full Moon
- E: Before new moon → Waning Crescent

But since only four phases are listed (new, first quarter, full, last quarter), if these are standard positions:

- B: First Quarter
- C: Full Moon
- D: Last Quarter
- E: New Moon

✔ Answer depends on diagram, but generally:
- B: First Quarter
- C: Full Moon
- D: Last Quarter
- E: New Moon

Building Vocabulary

Match the terms to their definitions.

#### Terms:
- phase
- eclipse
- umbra
- penumbra
- spring tide
- neap tide

#### Definitions:

1. The Moon’s appearance changes as it orbits Earth.
- ✔ Phase – This describes how much of the Moon’s surface is illuminated from Earth’s perspective.

2. A shadow cast by one object that blocks light from reaching another object.
- ✔ Eclipse – When the Moon or Earth casts a shadow that blocks sunlight.

3. The darkest part of a shadow where no direct sunlight reaches.
- ✔ Umbra – Total shadow; if you're here, you see a total eclipse.

4. The lighter outer part of a shadow where some sunlight reaches.
- ✔ Penumbra – Partial shadow; partial eclipse visible here.

5. When the Moon is in the same line as the Sun and Earth, causing high tides on both sides of Earth.
- ✔ Spring Tide – Occurs during new and full moons; higher than average tides.

6. When the Moon is at a right angle to the Sun, resulting in lower high tides.
- ✔ Neap Tide – Occurs during first and last quarters; smaller tidal range.

7. An event when the Moon passes between Earth and the Sun, blocking sunlight.
- ✔ Lunar Eclipse? Wait — no. That’s Solar Eclipse.

Wait — let’s fix that.

Actually:

- Solar Eclipse: Moon blocks Sun → seen from Earth.
- Lunar Eclipse: Earth blocks Sunlight from reaching Moon.

So correct matching:

7. An event when the Moon passes between Earth and the Sun...
- ✔ Solar Eclipse → But “solar eclipse” isn't in the word bank.

Wait — the word bank has: phase, eclipse, umbra, penumbra, spring tide, neap tide

So "eclipse" is the general term.

But the sentence says: *"when the Moon passes between Earth and the Sun..."* → this is a solar eclipse.

But since "solar eclipse" isn’t in the list, perhaps the intended answer is just eclipse.

But more precisely, the term eclipse fits broadly.

So:

7. An event when the Moon passes between Earth and the Sun...
- ✔ Eclipse — specifically solar eclipse, but “eclipse” is acceptable.

8. An event when Earth passes between the Moon and the Sun, casting a shadow on the Moon.
- ✔ Eclipse — again, this is a lunar eclipse, but still under eclipse.

But we need to match to one term per definition.

Let’s re-express:

Looking at the options:
We have: phase, eclipse, umbra, penumbra, spring tide, neap tide

So likely:

7. An event when the Moon passes between Earth and the Sun...
- ✔ Eclipse (specifically solar)

8. An event when Earth passes between the Moon and the Sun...
- ✔ Eclipse (lunar)

But both use "eclipse"? That might be a problem.

Alternatively, maybe the questions are designed to use eclipse for both.

But that's redundant.

Wait — perhaps the word bank includes other words?

No — based on what you wrote, only those six.

So possibly:

- 7. Eclipse (solar)
- 8. Eclipse (lunar)

But that’s not ideal.

Alternatively, maybe the question meant to say:

7. An event when the Moon passes between Earth and the Sun...
- ✔ Eclipse — yes

8. An event when Earth passes between the Moon and the Sun...
- ✔ Eclipse — again

But perhaps the key is to realize that both are types of eclipses, so eclipse is the correct term for both.

So:

7. ✔ Eclipse
8. ✔ Eclipse

But that seems odd.

Wait — maybe the word bank includes solar eclipse and lunar eclipse? But you didn’t list them.

Based on your original text:

> Terms: phase, eclipse, umbra, penumbra, spring tide, neap tide

So only those.

Therefore:

7. An event when the Moon passes between Earth and the Sun...
- ✔ Eclipse

8. An event when Earth passes between the Moon and the Sun...
- ✔ Eclipse

Even though both are types of eclipses, the general term is eclipse.

Alternatively, if the question expects specific types, then there’s a mismatch.

But since only eclipse is available, we go with that.

9. The area where the Moon's shadow falls on Earth.
- ✔ Umbra or Penumbra? Depends on depth.

But the term umbra is the darkest part.

But "area where shadow falls" could be umbra or penumbra.

But the best fit is umbra — the central dark shadow.

Wait — actually:

- Umbra: Total shadow
- Penumbra: Partial shadow

So if it says “the area where the Moon's shadow falls”, it could mean umbra (total) or penumbra (partial).

But typically, the umbra is the region where a total eclipse is seen.

But the question says “the area where the Moon’s shadow falls” — that’s umbra.

But technically, penumbra is also part of the shadow.

But in context, umbra is the main shadow.

Wait — better:

- The umbra is the darkest part of the shadow.
- The penumbra is the lighter outer part.

So:

9. The area where the Moon's shadow falls on Earth.
- ✔ Umbra — if it's the dark center
- But “falls” could mean the whole shadow.

But in science, the umbra is the core.

But let’s look at the next one.

10. The area where the Moon's shadow partially covers Earth.
- ✔ Penumbra — because it’s partial.

So:

9. The area where the Moon's shadow falls on Earth.
- ✔ Umbra — assuming they mean the dark central region.

But it's ambiguous.

Better:

- 9. The area where the Moon's shadow falls on Earth → Umbra
- 10. The area where the Moon's shadow partially covers Earth → Penumbra

Yes — that makes sense.

So:

9. ✔ Umbra
10. ✔ Penumbra

11. Tides caused by the combined gravitational pull of the Sun and Moon.
- ✔ Spring Tide — occurs during new and full moons when Sun and Moon align.

12. Tides caused when the Sun and Moon are at right angles to each other.
- ✔ Neap Tide — weaker tides due to opposing pulls.
