Geography | The study of the distribution and interaction of physical and human features on the earth. |
Absolute Location | The exact place where a geographical feature is found. |
Relative Location | Describes a place in relation to other places around it. |
Hemisphere | The earth is divided into two equal halves. |
Equator | The imaginary line that divides the north and south. |
Prime Meridian | The imaginary line that divides the east and west. |
Latitude Lines | Imaginary lines that run parallel to the equator. These locate north and south. |
Longitude Lines | Imaginary lines that go around the earth over the poles. These locate east and west. |
Place | The physical features and cultural landscape of a location. |
Physical (Nautral) Characteristics | Landforms, climate, vegetation. |
Human (Cultural) Characteristics | Language, religion, ethnicity, population. |
Location | A place's physical physical and human characteristics. |
Region | A group of places with at least one common physical or human characteristic, and may be determined by people's perceptions, or viewpoints influenced by one's own culture and experiences. |
Formal Region | Areas in which certain a characteristic is found throughout them. |
Functional Region | Consists of a central place and the surrounding places affected by it. |
Perceptual Region | Defined by people's attitudes and feelings about areas. |
Cartography | Map making. |
Map Projection | A way of drawing the earth's surface by presenting a round earth on flat paper. |
Topographical Map | Shows the natural and man made features of the earth. |
Geographic Information System (GIS) | Uses digital map information to produce a special map. |
Global Positioning System (GPS) | Uses a series of 24 satellites called navstar. They send the exact latitude, longitude, altitude, and time to a hand held receiver. |
Core | The center of the earth and is made up of iron and nickel. |
Mantle | A soft layer of molten rock that is about 1800 miles thick. |
Crust | Thin layer of gases called the atmosphere. It contains the air we breathe. It also protects the earth from radiation and space debris. |
Atmosphere | Layer around earth that contains air and protects the earth from the radiation and the space debris; where weather and climate take place. |
Lithosphere | The solid rock portion of earth, some of the lithosphere is below water and forms the ocean floor. |
Hydrosphere | Made of water, including oceans, seas, rivers, lakes, and water in the atmosphere. |
Biosphere | The part of earth where plants and animals live. |
Plate Tectonics | Heated rock rises then cools and circulates downward; enormous moving pieces of earth's lithosphere. |
Continental Drift Theory | Maintains that earth was once a super continent that slowly. |
Pangea | The super continent. |
Plate Movement | Tectonic plates move in one of four ways: 1) Moving apart (Divergent) 2) Diving under another plate 3) Collision (Convergent) 4) Slide past one another (Transformation) |
Ring of Fire | A group of volcanoes and volcanic islands around the rim of the Pacific Ocean. |
Weathering | The breakdown of rick at or near the earth's surface into smaller and smaller pieces. |
Mechanical Weathering | When a rock is physically weakened or broken: most common is when water freezes and cracks in rock. |
Chemical Weathering | Alters the chemical make up of a rock; carbon dioxide and water are the most important factors. |
Acid Rain | A type of chemical weathering caused by air pollution and water. |
Erosion | The moving of weathered materials; the single greatest cause of erosion is water, and the second greatest cause is wind. |
Delta | Landform created when sediment is deposited as a river enters the ocean. |
Glacier | A large, long lasting mass of ice. |
Glacation | The changing landforms by slowly moving glaciers. |
Coriolis Effect | The apparent curvature of global winds, ocean currents, and everything else that moves freely across the Earth's surface; influences wind direction around the world: Northern hemisphere curves its winds to the right and the Southern curves its to the left |
Weather | The condition of the atmosphere at a particular location and time. |
Climate | The term for weather conditions in a particular location over a long period of time. |
Precipitation | As warm air rises it cools and loses the ability to hold water vapor; the water vapor condenses and water droplets form a cloud; when the amount of water in the clouds is to heavy to hold it falls as rain. |
Convectional | Typically of hot climates, convection occurs after morning sunshine heats the warm moist air; clouds form in the afternoon and rain falls. |
Rain Shadow (Orographic) | Associated with mountain areas, orographic storms drop more rain on the windward side of the mountain. |
Frontal | Mid-Latitude frontal storms feature cold dense air masses that push lighter air mass upward, causing precipitation to form. |
Desalinization | One of many process that remove some salt and other minerals from water, to provide fresh water. |
Human Adaptation | A change in human behavior to cope with the environmental conditions.(Example: Change in clothing) |
Human Modification | Humans have actually changed some part of the physical environment. (Example: Building a Dam) |
Green House Effect | A process by which radiative energy leaving the planetary surface is absorbed by some atmospheric gases, called green house gases. |
El Nino | A weather pattern created by the warming of the waters off the west coast of South Africa, which pushes warm water and heavy rains towards the Americas and produces drought conditions in Australia and Asia. |
Global Warming | The increase in the average temperature of Earth's near surface air and oceans since the mid-20th century and its projected continuation. |
Deforestation | The clearance of forests by logging and/or burning (popularly known as slash and burn). |
Natural Hazard | An uncontrollable natural even of unusual magnitude that threatens the activities of people or people themselves. |
Solstice | The day when earth is at the farthest north and south latitude. |
Equinox | Two times a year when day and night are exactly equal in length. |
Hurricane | Storms that occur over warm tropical ocean waters. |
Blizzard | A tense snow form. |
Tornado | Violently rotating column of air extending from the base of a thunder storm to the ground. |
