Planet Earth II
Earth is the fifth largest of the planets in the solar system — smaller than the four gas giants, Jupiter, Saturn, Uranus and Neptune, but larger than the three other rocky planets, Mercury, Mars and Venus. Earth has a diameter of roughly 8,000 miles (13,000 kilometers), and is round because gravity pulls matter into a ball, although it is not perfectly round, instead being more of an “oblate spheroid” whose spin causes it to be squashed at its poles and swollen at the equator.

Compare Contrast and Debate
Background: Nearly 75% of the continental surfaces are covered by sedimentary rocks, although they form about 5% of the crust. About 10% of sedimentary rocks are limestones.
- Position A: The importance of limestone as a building material makes it among the most important rock-types for high school students to recognize and understand.
- Position B: While limestone is an important building material, there are several other more-important rock types which should be recognized and understood by students.
