- Plain
- large reatively flat areas
- Plateau
- relatively flat raised areas of land
- Folded Mountains
- mountains created when rock layers are squeezed from opposite sides,causing them to buckle and fold
- Upwarped Mountains
- mountains formed when earth's crust is pushed up and eroded,froming sharp peaks ridges
- Fault-Block Mountains
- Jagged mountains formed from huge,tilted blicks of rocks that are separated from surrounding rock by faults
- Volcanic Mountains
- mountains created when magma whithin earth escapes to the surface,building cones of lava and ash
- Equator
- an Imaginary line,at 0 latitude,that circules earth exactly halfway between the north and south;separates earth into the northern hemisphere
- Latitude
- a distance north or south of the equator,expressed in degrees
- Prime Meridian
- an imaginray line running from the north pole to the south pole,passing through Greenwich,England;the 0 reference line for longitude
- Longitude
- a distance east or west of the prime meridian,expressed in degrees
- International Date Line
- an imaginary line in the Pacific Ocean where we change calendar days
- Mercator Projection
- a map projection method using parallel longitude lines,their areas are distorted
- Robison Projection
- a map projection method using curved longitude lines,has a little distortion
- Topograpic Map
-
a map that uses contour lines uses contour line to show changes in elevations at earth's
surface - Contour Line
- a line on a topograpic map that connects points of equal elevation
- Contour Interval
- the difference in elevation between two side-by-side contour lines
- Map Legend
- explains what the symbols used on the map mean
- Map Scale
- is the realationship between the distance the on the map and actual distance
- Landsat
- detect different wavelengths of energy reflected or emitted from earth's surface
- Topex-Poseidon Satellite
- uses radar to compute the distance to the ocean's surface
- Sonar
- refers to the use of sound waves to detect oceanbottom features
- Coastal Plains are also
- lowlands
- To show distances a _____________ is used on maps
- map scale
- Sea Beam maps
- show contours of the ocean
- Lansat Sattelites use measurements of ________________ that are converted into detailed maps of landforms
- wavelenghts and intensity of energy
- Landforms formed by molten materials are __________ mountains
- volcanic
- Areas of equal elevation
- are connected by contour lines
- To find an exact location on a mpat
- use latitude and longitude linges
- if you travel ____________ across the International Date Line you lose one day
- west
- A road map is drawn to a _____________ projection
- conic
- The process that people use to prouduce modern maps
- uses satellite photos
- Meridains _________ the poles
- meet at
- What is the difference in plains and plateaus
- they both are flat but plateaus rise
- In what ways has technology changed map making in the last 100 years
- computers, radar and satellites have made it possible to make a much greater variety of detailed maps of both land and sea features
- Would a topographic map of the Rocky Mountains have a large or small contour interval
- The Rocky Mountains have high relief so the contour interval would be large
- Compare a Mercator projection map to a Rovinson projection map
- a mercator projection map has parallellel latitiude linge and parellell longitude line. A Robinson projection map has parallel latitude lines and curved longitude lines
