Download What is wave? How are EM waves different from mechanical waves?

 Topic: Unit 10 Earth’s Energy Budget, EM waves, Star Life cycle Name: Class/Period: Date: Learning Target(s): I can recognize the Sun’s energy reaches Earth as Electromagnetic wave energy. I can describe the features of Electromagnetic waves. I can relate the nuclear reactions in stars the star stages and the elements produced. Questions: What is Earth’s Energy Budget? Has Earth’s Energy Budget historically been balanced or unbalanced? What gases contribute to the green house effect? Notes: What is wave?

Summary: Questions: Sketch and label the Star Life cycle. Which stage of a star’s life cycle releases the most EM energy? How do Red Giants and Super Massive red giants differ? What element is present as all stars begin to form? What type of nuclear reaction occurs as stars form? Lightly shade the elements that are formed in the core of star due to nuclear fusion (before the supernova stage). Notes: What is the significance of the Supernova stage to the formation of elements?
