No Pressure!

Here’s a series of astronomical questions, with no marks at stake – just for fun!

1. The Seasons

The Earth's orbit is not quite a perfect circle. (That much is indeed true.)

Consider this claim: summer occurs and the hottest days of the year are in July because that is when the Earth is closest to the sun.

A: True

or B: False?

2. Black Holes

If the sun were to become a black hole, the Earth and all the other planets in the Solar System would be sucked into it.

A: True

or B:False?

3. Weightlessness

An astronaut in the Space Shuttle feels weightless because he or she is beyond the Earth's gravity.

A: True

or B:False?

4. Lunar Phases

The moon goes through its phases (new, crescent, full, etc) because of the different amount of the Earth's shadow which falls on it from time to time.

A: True

or B:False?

5. The Flat Earth

Until the time of Columbus, it was believed by almost all learned people that the world was flat.

A: True

or B:False?

6. The Full Moon

The full moon is measurably larger when it is close to the horizon, smaller when it is overhead.

A: True

or B:False?

7. Moving Water

If you pull the plug in an ordinary sink full of water, or flush a toilet, it will drain out while circulating (swirling) in one direction in the Northern Hemisphere. Water in the identical sink or toilet would swirl in the other direction in the Southern Hemisphere.

A: True

or B:False?

8. The Spinning Earth

If the Earth were to gradually slow down its rotation (spin) and come to a complete stop, we would all go floating off into space.

A: True

or B:False?

9. Upside-Down

From Australia, the moon appears to be upside-down relative to the way we see it.

A: True

or B:False?
