Chapter 23.1
• Which are the terrestrial planets? Mercury, Venus, Earth and Mars • Which are the Jovian Planets? Jupiter, Saturn, Uranus, and Neptune. • What are the differences between the Jovianand the terrestrial planets? Size is the most obvious difference between Jovian and the terrestrial planets. But density, chemical makeup, and rate of rotation are other differences as well. • Howdid the solar system form? According to the nebular theory, the solar system formed from a rotating disk of dust and gases. Planetesimal: Small, irregularly shaped body formed by colliding matter.Nebula: A cloud of dust and gas in space. • How does the distance from the sun affect the size and composition of planets? Due to the amount of heat that is generated by the sun.
Chapter 23.2
• Whichinner planet is the smallest? Mercury. • How does Venus compare with Earth? Venus is similar to Earth in size, density, mass and location in the solar system.
•
Make a chart with theterrestrial planets and their most distinguishing characteristics.
• Why are surface temperatures so high in Venus? The greenhouse effect has heated the planet's atmosphere to 475 degreesC.
Chapter 23.3• Make a chart with outer planets and the distinguishing characteristics of each?
• Which planets have rings? Jupiter, Saturn, Neptune and Uranus. • Which planets Axis of rotation lies nearlyparallel to the plane of its orbit? What may have caused this? Uranus and it was caused by Uranus passing in front of a distant star and blocking its view. • Why Pluto is is not considered a planet? Ithas not cleared the neighborhood around its orbit.
Chapter 23.4 Asteriod: Small rock bodies that orbit the sun. Comet: Pieces of rocky and metallic materials held together by frozen, ammonia,methane, carbon dioxide, and carbon monoxide. Coma: A glowing head of a comet. Meteoroid: Small solid particle that travels through space. Meteor: Meteoroids that enter Earth's atmosphere and burn up....
