PPT-The Solar System Activating Strategy: Comparing Planets

Fill in the Comparing Planets Chart with what you already know about the planets How does Earth compare to other planets in the solar system S6E1c Compare and contrast planets in terms of size relative to earth surface and atmospheric features relative distance from the sun ability to support life. The processes by which stars and planets form are active areas of research in modern astrophysics. The formation of our own solar system is central to the first half of our course, and important to the second half as well when we study the formation of stars. The outer planets are called Jovian or Jupiter-like.. These planets are made of gas and are several times more massive than the Earth.. The Jovian planets grew to present size in about 10 million years.. Introduction & Components . Activity . Look at the projector, is it giving off its own light? . Look at the white board is it giving off its own light? . How is it that the white board seems as if it is producing its own light? . Chapter 23. Prentice Hall Earth Science. Touring Our Solar System. Section 1. Prentice Hall Earth Science. 23.1 Objectives. List . how the major terrestrial planets differ from Jovian planets. Explain . Nebula . Theory. Summing Up. SNT Explaining the Solar System. The Solar System’s disk shape. Inherited from the motion of materials in the solar nebula. . The planets and moons mostly rotate and revolve in the same directions because they evolved from the same gas cloud. . 25.5. Any theory about the origin of the solar system must explain. why all of the planets’ orbits lie more or less in a plane . Why all of the planets orbit the sun in the same direction. . It must also explain the differences in size and composition between the terrestrial planets and the gas giants.. By . Ben . Mercury. The distances of planets from each other and from the Sun are often measured in Astronomical Units, AU.  One AU is the average distance between the Earth and the Sun, 93 million miles.  Using this system of measurement, Mercury is 0.39 AU from the Sun..
