Chapter 2
Patterns in the Sky—Motions of Earth
Study Plan
Learning Goals
By the conclusion of this chapter, you should be able to:
Explain how the stars appear to move through the sky, and how the motion of the stars differs when viewed from different latitudes on Earth.
Explain why there are different seasons throughout the year.
Summarize how the motion of the Moon in its orbit about Earth, together with the motion of Earth and the Moon around the Sun, shapes the phases of the Moon and the spectacle of eclipses.
Sketch the alignment of Earth, Moon, and Sun during different phases of the Moon.
Prepare and Assess
Read Chapter 2 in your textbook or
ebook.
Take the
Diagnostic Quiz
to assess your understanding of the basic concepts and identify gaps in your understanding of the reading.
