Prehistoric Astronomy (The Night Sky)

Front

What are cyclic astronomical phenomena?

Back

Cyclic astronomical phenomena are regular, predictable events in the night sky, such as the phases of the Moon, the positions of stars, and seasonal changes, which help observers make predictions about celestial events.

Front

How do cyclic astronomical phenomena assist ancient observers?

Back

They help ancient observers predict seasonal changes, set timekeeping methods, and build monuments to celebrate celestial events.

What does a waxing Moon indicate?

Back

A waxing Moon is a phase where the Moon appears to grow more illuminated each night as seen from Earth.

Front

How much earlier does the Moon rise each night?

Back

The Moon rises approximately 50 minutes later than the night before.

Front

What causes the apparent rising of stars earlier each night?

Back

The apparent rising of stars earlier each night is caused by the revolution of Earth around the Sun.

Front

What phase of the Moon is observed when the far side is fully lit?

Back

When the far side of the Moon is fully lit, we observe a New Moon from Earth.

Front

Define 'revolution' in the context of astronomy.

Back

Revolution refers to the movement of one celestial body around another, such as the Earth's orbit around the Sun.

Front

What is the significance of the tilt of Earth's axis?

Back

The tilt of Earth's axis is significant because it causes the seasons and affects the apparent position of celestial bodies in the sky.

Front

Explain the term 'apparent motion' in astronomy.

Back

Apparent motion refers to the perceived movement of celestial bodies as observed from Earth, which can differ from their actual motion due to Earth's rotation and revolution.

Front

What is the difference between a Full Moon and a New Moon?

Back

A Full Moon occurs when the entire face of the Moon is illuminated, while a New Moon occurs when the Moon is between the Earth and the Sun, making it invisible from Earth.
