The surface of the moon has two main types of areas: 1. The bright colored highlands that have higher elevations and more impact craters, and 2. The darker colored low lying maria formed from volcanic eruptions on the moon where basaltic lava flooded the surface. Use the photo below to complete the following exercises. 119 1. Label the lunar highlands (A), maria (B), basalt filled impact crater (C), and two rayed craters (D) (look like spokes of a wheel coming out of crater. 2. What do you think makes up the “rays” in a rayed crater? 3. Which terrain (highlands or maria) have more impact craters? What does the amount of cratering tell you about the age of each terrain? Examine the following photos of the nearside (top) and far side (bottom) of the moon. 1. Why don’t we ever see the far side of the moon? 2. What do you notice different about the two sides of the moon? Why do you think there is this difference?

Life Cycle Stages Each stage of a star’s life involves some process within the star (fusion in its core, fusion in a shell, electron degeneracy, etc.) trying to prevent gravity from crushing the star into a singularity. Below is a diagram showing six stages in the life of a star
