Unit 3 Performance Task

Front

What is the orbital tilt of the moon's revolution around the Earth?

Back

The angle at which the moon orbits the Earth, which affects the occurrence of lunar phases and eclipses.

Front

What is a solar eclipse?

Back

A solar eclipse occurs when the moon passes between the Earth and the sun, blocking all or part of the sun's light.

Front

What is a lunar eclipse?

Back

A lunar eclipse occurs when the Earth passes between the sun and the moon, causing the Earth's shadow to fall on the moon.

Front

What are the positions of the Earth during a solar eclipse?

Back

The Earth must be at a position where the moon is directly between the Earth and the sun.

Front

What are the positions of the Earth during a lunar eclipse?

Back

The Earth must be at a position where it is directly between the sun and the moon.

Front

What is the significance of Earth's axial tilt?

Back

Earth's axial tilt affects the seasons and the occurrence of eclipses.

Front

What are solstices and equinoxes?

Back

Solstices are the points in the year when the sun is at its highest or lowest point in the sky at noon, while equinoxes are when day and night are of equal length.

Front

How does the model predict lunar phases?

Back

The model shows the relative positions of the Earth, moon, and sun, which helps predict the phases of the moon.

Front

What is the importance of showing Earth's axis in models?

Back

Showing Earth's axis is crucial for understanding the tilt and its effect on seasons and eclipses.

Front

What is the counterclockwise motion of Earth?

Back

The direction in which the Earth revolves around the sun, which is important for understanding seasonal changes.
