Conic Projection
|
a map projection made by projecting points and lines from a globe onto a cone; it produces accurate maps of areas smaller than the whole Earth, such as a nation or a state.
|
|
Contour Interval
|
The difference in elevation between two side-by-side contour lines on a topographic map.
|
|
Contour Line
|
A line on a topographic map that connects points of equal elevation.
|
|
Equator
|
An imaginary line, at 0° latitude, that circles Earth exactly halfway between the North and South Poles; separates Earth into the northern hemisphere and the southern hemisphere.
|
|
Fault-block mountains
|
Jagged mountains formed from huge, tilted blocks of rock that are separated from surrounding rock by faults.
|
|
Folded Mountain
|
Mountains created when rock layers are squeezed from opposite sides, causing them to buckle and fold.
|
|
International Date Line
|
The 180° meridian, on the other side of Earth from the prime meridian; an imaginary line in the Pacific Ocean where we change calendar days.
|
|
Landsat Satellite
|
Satellite that collects information about Earth's surface by using a mirror to detect different wavelengths of reflected or emitted energy.
|
|
Latitude
|
A distance north or south of the equator, expressed in degrees.
|
|
Longitude
|
A distance east or west of the prime meridian, expressed in degrees.
|
|
Map Legend
|
The key on most maps that is used to explain what the symbols on the map mean.
|
|
Map Scale
|
The relationship between distances drawn on a map and actual distances on Earth's surface.
|
|
Mercator projection
|
A map-projection method using parallel longitude lines; continent shapes are accurate, but their areas are distorted.
|
|
Plain
|
A landform that is a large, relatively flat area; interior plains and coastal plains make up one-half the land area in the united States.
|
|
Plateau
|
Landforms created next to mountains, when forces within Earth raised high, relatively flat areas of nearly horizontal rocks.
|
|
Prime Meridian
|
An imaginary line running from the North Pole to the South Pole, passing through Greenwich, England; the 0° reference line for longitude.
|
|
Robinson projection
|
A map-projection method using curved longitude lines; continent shapes and land areas are accurate with little distortion.
|
|
Sonar
|
The use of sound-wave echoes to detect the size and shape of structures found underwater.
|
|
Topex-Poseidon Satellite
|
Satellite that collects information about Earth's oceans by using radar.
|
|
Topographic Map
|
A map that uses contour lines to show changes in elevation at Earth's surface; shows natural features such as lakes and cultural features such as cities and dams.
|
|
Upwarped mountains
|
Mountains formed when Earth's crust is pushed up and eroded, forming sharp peaks and ridges.
|
|
Volcanic Mountain
|
Mountains created when magma within Earth escapes to the surface, building cones of lava and ash.
