| system | an organized group of parts that work together to form a whole |
| system | Earth, terrarium |
| atmosphere | the mixture of gases and particles that surrounds and protects the surface of the Earth. |
| hydrosphere | made up of all the water on Earth in oceans, lakes, glaciers, rivers, and streams and underground |
| biosphere | includes all llife on Earth, in the air, on the land, and in the waters |
| geosphere | includes all featrues on Earth's surface-the continents, islands, and sea floor- and everything below the surface |
| relief map | shows how high or low each feature is on Earth |
| map scale | relates to distances on a map to actual distances on Earth's surface |
| map legend | key |
| map legend | a chart that explains the meaning of each symbol used on a map |
| latitude | a distance in degrees north or south of the equator |
| equator | 0 degrees latitude |
| prime meridian | an imaginary line that stretches from the North Pole through Greenwich, England, to the South Pole |
| prime meridian | what longitude is based on |
| longitude | distance in degrees east or west of the prime meridian |
| longitude | beginning at the prime meridian, _____ lines are labeled east to west. |
| projection | a way of representing Earth's curved surface on a flat map |
| cylindrical projection | projection that shows earth as if the map were a large cylinder wrapped aroudn the planet |
| GPS | network of satellites that are used to find the latitude, longitude, and elevation above sea level |
| conic projection | projection based on the shape of a cone |
| planar projection | projection developed to help people find the shortest distance between two points |
| topography | the shape or features of the land |
| topographic maps | the types of drawings Pitti used to do for a living |
| contour lines | wiggly lines on the map |

| satellite | an object that orbits a more massive object |
| remote sensing | the use of scientific equipment to gather information about something from a distance |
| remote sensing | use of binoculars is an example |
| sensor | a mechanical or electrical device that receives and responds to a signal, such as light |
| sensor | collects infrmation abou the different types of energy coming from the Earth's surface |

1.Lithosphere- the solid ,rocky outer crust of the earth, about 1-20km thick. 2.mantle or asthenosphere-the thickest layer of the earth, about 3000km thick, made up of rock melted to a thick,pastry texture, like peanut butter or toothpaste.Remember that rock begins to change from a solid to a liquid at about 2000 degrees. 3.Outer core-liquid, molten rock, about 5000 degrees F. This layer is about 2200 km thick 4.Inner core-made up of earths heaviest materials, the inner core is solid, although at about 5000 degrees it is certainly hot enough not only to melt, but to run like water. The reason it is solid is that melts have to be able to expand, and the pressure of the weight of the outer core, mantle and lithosphere keeps the inner core frombeing able to expand, so threrefore it cannot become a liquid, even tho it is hot enough to melt. The inner core is about 1200 km across. 5.Plates-large sections of the earths solid crust, like pieces of eggshell on a cracked egg. 6.Continental Drift-a theory put forth by a German scientist, Alfred Wegener, in 1912. |
