Nar Ramirez The 3 rd Planet August 30, 2007 Chapter 1 Outer Space (Not Clear For Boundary) Thermosphere (Not Clear For Boundary) Mesopause Mesosphere (decrease in temperature) Stratopause Stratosphere (ozone layer/ increase in temperature) Tropopause Troposphere (We live here/decrease in temperature) The Earth has two principal motions: Rotation (23.5 degrees away from it/on it’s axis) & Revolution (revolves around the sun at 107,000 km per hour) Seasons Seasons exist because of the tilt in the earth’s axis. Summer in Northern = Furthest Away from the Sun Winter in Northern = Closer to the Sun Summer in Southern = Closer to the Sun Winter in Southern = Farther Away from the Sun Summer Solstice occurs on June 21 or 22. You get the most direct sunlight. Winter Solstice occurs on December 21 or 22. You get the less direct sunlight. Autumn Equinox is September 22 or 23. Spring Equinox is March 21 or 22. Mechanism of Heat Transfer All forms of matter (solid, liquid, or gas) are composed of atoms or molecules that are in constant motion. The colder the slower. The hotter the faster. All matter is said to contain thermal energy. Temperature is described as the “hotness” or “coldness” of an object. Conduction is the transfer of heat through matter by molecular activity. The energy of molecules is transferred through collisions from one molecule to another, with the heat flowing from the higher temperature to the lower temperature. Convection is the transfer of heat by the movement of a mass or substance from one place to another. It can take place only in liquids & gases.

Advection: horizontal convective motions such as winds. Convections: vertical convective motions such as the atmosphere. Radiation: only mechanism of heat transfer that can transmit heat through the relative emptiness of space. Paths Taken by Incoming Solar Radiation Radiation transmits energy through vacuum of space at 300,000 km per second. About 25 % of solar radiation penetrates directly to Earth’s surface without interference. The rest is scattered or reflected back to space. Gases are selective absorbers, meaning that they absorb strongly in some wavelengths. Temperature Measurement and Data
