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.
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.
A distance north or south of the equator, expressed in degrees.
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.
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.
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.
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.
