Unit 3 Performance Task

Front

What are lunar phases?

Back

Lunar phases are the different appearances of the Moon as seen from Earth, caused by the relative positions of the Earth, Moon, and Sun.

Front

What is a lunar eclipse?

Back

A lunar eclipse occurs when the Earth passes between the Sun and the Moon, blocking sunlight from reaching the Moon.

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 the significance of the Moon's orbital tilt?

Back

The Moon's orbital tilt affects the occurrence of eclipses and the visibility of lunar phases from Earth.

Front

What does the position E1 indicate in the model?

Back

Position E1 indicates a specific location of Earth in relation to the Moon and Sun, which can affect lunar phases and eclipses.

Front

How does the Earth's position at E2 predict eclipses?

Back

At position E2, the model predicts solar and lunar eclipses at positions M2 and M4 based on the alignment of the Earth, Moon, and Sun.

Front

What is the role of the Earth's tilt in lunar phases?

Back

The tilt of the Earth affects the angle of sunlight hitting the Moon, influencing the visibility of its phases.

Front

What is the relationship between the Moon's revolution and lunar phases?

Back

The Moon's revolution around the Earth causes the different lunar phases as it reflects sunlight from various angles.

Front

What is the importance of understanding lunar phases?

Back

Understanding lunar phases helps predict the timing of eclipses and the appearance of the Moon in the night sky.

Front

What does position M3 represent when Earth is at E1 during a new moon?

Back

Position M3 represents the location of the Moon when Earth is at E1 and there is a new moon.
