Chapter 1 Section 1.1 Planet Earth Planets • Inner planets: Mercury, Venus, Earth, and Mars (made up of rock) • Outer planets: Jupiter, Saturn, Uranus, and Neptune (made up of gases) • Pluto Solar System Organisms • Organisms- living things Lithosphere • Lithosphere- layer of land that forms Earth’s surface • Includes: rocks, soil, and sand Hydrosphere • Hydrosphere- includes all of the oceans, lakes, rivers, underground water, and clouds Atmosphere • Atmosphere- layer of air that surrounds the Earth How can Earth support life? • Presence of liquid water • Liquid water in the hydrosphere stores heat! • Atmosphere- air is made up of nitrogen, oxygen, carbon dioxide, and water vapor. Water Characteristics • Water absorbs heat during warm periods and releases it during cold periods. • Water on Earth helps maintain a steadier surface temperature than other planets! Energy comes from the sun • Form of waves • Each type of wave has a different wavelength and are invisible. • Visible spectrum can be seen by the human eye (light) Light Spectrum Ecology • Ecology- interactions among nonliving and living parts of the Earth • Word “ecology” comes from the Greek word “oikos”, meaning “home”. • So, we can say that ecology is the study of the Earth, which is the home of living organisms. Review!!! • What parts of Earth make up the hydrosphere? • What characteristics of Earth enable it to support life? • The temperature of a planet is determined, in part, by its distance from the sun. Which planets would you expect to be warmer than Earth? Which ones would be colder?
