Astronomy-1

Perhaps the most easily identified object in the sky (aside from the sun) is the moon. However, its most basic phenomena are often misunderstood. In a 2 to 3 paragraph essay, explain what causes the following phenomena:

• Phases of the moon
• Solar eclipse
• Lunar eclipse 
• Include a description of the observed shapes of the moon during a gibbous phase and a lunar eclipse, and how they differ.
