Solar Eclipse

2. When does a lunar or solar eclipse occur?

Select all that apply

A
A) When the Earth’s orbit aligns with the Moon’s orbit at the equinoxes.
B

C
C) When the Moon is at its farthest point from Earth in its orbit.
D
D) When the Earth's axis is tilted at 23.5 degrees.

GeoGebra 3D Visualization

4. How does GeoGebra help in visualizing the intersection of the ecliptic and celestial planes?

Select all that apply

A
A) By showing the distance between the Earth and Moon in real-time.
B
B) By allowing the user to adjust the Earth's orbital position and the Moon's position relative to the Earth.
C
C) By plotting the coordinates of the Sun's path across the sky.
D
D) By illustrating the tilt of the Earth's axis during the solstices.

Moon’s position around the Earth

5. In the GeoGebra activity, how is the Moon’s position around the Earth controlled?

Select all that apply

A
A) By a slider that adjusts the Moon's position based on its orbital tilt.
B
B) By a slider that controls the Earth's position in its orbit.
C
C) By a slider that rotates the Moon's orbital plane.
D
D) By a slider that changes the position of the Sun.
