Eclipses can only observed every year (i.e. solar eclipse) not every day. They are rare phenomena we can observed in the sky when celestial objects align in space.
TRUE 2. Eclipses only happen when the moon aligns with the sun and earth.
This is true because the celestial objects like the sun, moon, and earth must align first either totally or partially for an eclipse to occur from a reference point.
TRUE 3. The only shadows that we can see are the shadows of the earth and the moon.
The sun has no shadow. Remember that the sun is a natural source of light and known as a big ball of fire.
TRUE 4. Solar eclipse occurs when the moon comes directly between the sun and the earth.
The alignment should be Sun-Moon-Earth so that solar eclipse will occur. Moon is in the middle.
TRUE 5. Looking directly in the sun can harm your eyes.
The sunlight contain harmful UV rays that may burn and damage your eye tissues. It results to temporary to permanent blindness. An example of illness caused by the sun to the eye is solar keratitis.
TRUE 6. It was Isaac Newton who concluded that earth was a sphere.
Isaac Newton theorized that the shape of the earth is a sphere, specifically oblate spheroid.
FALSE 7. The moon shadow is bigger than the earth's shadow.
No. Rather, the earth's shadow is way bigger, approximately 3.7 times, than the moon's. Since the earth's diameter is longer than the moon, the same goes with its shadow.
TRUE 8. Lunar eclipse happens when the earth's shadow falls on the moon.
The alignment of lunar eclipse is Sun-Earth-Moon, so the Earth casts shadow on the Moon, thus, blocking the light from the Sun.
TRUE 9. When the moon is completely within the umbra it becomes totally dark.
The umbra is the fully shaded or darkest part of a shadow. So when the moon is completely within it, we cannot see the moon [from the earth] and it's totally dark.
FALSE 10. A total lunar eclipse occurs when only a portion of the moon moves into earth's umbra.
A total lunar eclipse means that the moon is completely within the earth shadow's umbra. If not (i.e. only a portion), the result is partial lunar eclipse.
TRUE 11. The sun is the ultimate and cheapest source of energy.
It is called as such because it is the primary source of energy of most creatures and cycles on earth. It is the cheapest because it is from nature and is free for all.
TRUE 12. The earth is the planet where we live.
FALSE 13. The earth has two moons.
Earth has one moon called Moon.
TRUE 14. The moon is the earth's nearest neighbor.
The nearest celestial neighbor of the Earth is Moon. It is the most visible celestial object seen by the naked eye.
