|---|---|---|---|---|---|
| Asthenosphere | the soft layer of the mantle on which the tectonic plates move
🗑
|
||||
| Chemical Weathering | the chemical breakdown and decomposition of rocks by natural processes in the environment
🗑
|
||||
| Continental Drift | the hypothesis that a single large landmass broke up into smaller landmasses to form the continents; which then drifted to their present locations; the movement of continents
🗑
|
||||
| Contour Interval | the difference in elevation between one contour line and the next
🗑
|
||||
| Contour Line | a line that connects points of equal elevation on a map
🗑
|
||||
| Convergent Boundary | the boundary between tectonic plates that are colliding
🗑
|
||||
| Deformation | the bending, tilting and bending off of Earth's crust; the change in the shape of rock in response to stress
🗑
|
||||
| Deposition | in geology, the process in which material is laid down
🗑
|
||||
| Divergent Boundary | the boundary between two tectonic plates that are moving away from each other
🗑
|
||||
| Erosion | the process by which wind, water, ice or gravity transports soil and sediment from one location to another
🗑
|
||||
| Geographic Information System | a system for capturing, storing, retrieving, analyzing, manipulating and displaying geographic data
🗑
|
||||
| Global Positioning System | a network of satellites that orbit Earth to measure positions on Earth's surface
🗑
|
||||
| Index Contour | on a map, a darker, heavier contour line that is usually every fifth line
🗑
|
||||
| Lithosphere | the solid, outer layer of Earth that consists of the crust and the rigid upper layer of the mantle
🗑
|
||||
| Magnetic Reversal | the process by which Earth's magnetic north pole and magnetic south pole switch positions periodically; a change in the direction in which Earth's magnetic field points
🗑
|
||||
| Physical Weathering | the mechanical breakdown of rocks into smaller pieces that is caused by natural processes and that does not change the chemical composition of the rock material
🗑
|
||||
| Plate Tectonics | he theory that Earth's outer layer is made up of large, moving pieces called tectonic plates; the theory that explains how plates interact and how those interactions relate to process such as earthquakes and mountain building
🗑
|
||||
| Relief | the difference between the highest and lowest elevations in a given area; the variations in elevation of a land surface
🗑
|
||||
| Remote Sensing | the process of gathering and analyzing information about an object without physically being in touch with that object
🗑
|
||||
| Scale | the relationship between the measurements on a model, map or diagram and the actual measurement or distance
🗑
|
||||
| Sea-Floor Spreading | the process by which new oceanic lithosphere (sea floor) forms when magma rises to Earth's surfaces at mid-ocean ridges and solidifies, as older, existing sea floor moves away from the ridge
🗑
|
||||
| Slope | a measure of the slant of a line; the ratio of rise over run
🗑
|
||||
| Subduction | the process by which one lithospheric plate moves beneath another plate as a result of tectonic forces
🗑
|
||||
| Tectonic Plate | a block of lithosphere that consists of the crust and the rigid, outermost part of the mantle
🗑
|
||||
| Theory | a system of ideas that explains many related observations and is supported by a large body of evidence acquired through scientific investigation
🗑
|
||||
| Topographic Map | a map that shows the surface features of Earth
🗑
|
||||
| Topography | the size and shape of the land surface features of a region, including its relief
🗑
|
||||
| Transform Boundary | the boundary between tectonic plates that are sliding past one another horizontally
🗑
|
||||
| Weathering | the natural process by which atmospheric and environmental agents, such as wind, rain and temperature changes disintegrate and decompose rocks
🗑
