Front

What are the layers of the Moon?

Back

The Moon has three main layers: core, mantle, and crust.

Front

Why do we always see the same side of the Moon from Earth?

Back

We always see the same side of the Moon because its rotation period is the same as its orbit period around Earth.

Front

Is the Moon's gravity stronger or weaker than Earth's gravity?

Back

The Moon's gravity is weaker than Earth's gravity.

Front

What is the phase of the Moon when it is more than half illuminated but not fully illuminated?

Back

The phase is called Waning Gibbous.

Front

What does it mean for the Moon to be phase-locked?

Back

Being phase-locked means that the Moon's rotation period matches its orbital period around Earth, causing the same side to always face Earth.

Front

What is the significance of the Moon's core?

Back

The core of the Moon is believed to be small and partially molten, contributing to its overall structure and geological activity.

Front

What is the composition of the Moon's crust?

Back

The Moon's crust is primarily composed of oxygen, silicon, magnesium, iron, calcium, and aluminum.

Front

How does the Moon's gravity affect tides on Earth?

Back

The Moon's gravity pulls on Earth's water, creating tidal bulges that result in high and low tides.

Front

What is the difference between a waxing and waning moon?

Back

A waxing moon is increasing in illumination, while a waning moon is decreasing in illumination.

Front

What are the main phases of the Moon?

Back

The main phases of the Moon are New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, and Waning Crescent.
