large, flat areas which often have thick, fertile soils and grassy meadows.
stretch along coastal areas and are often called lowlands.
are in the central part of a continent
flat, raised areas of land made up of nearly horizontal rocks; their edges rise steeply from the area around them.
tower above the surrounding land
form when rock layers are squeezed from opposite sides, causing the rock layers to fold like a rug pushed up against the wall
forces inside Earth push the crust up to form?
form when tilted blocks of rock are separated by faults from the surrounding rock.
layers of molten material pile up forming cone-shaped?
imaginary grid created when lines of latitude and longitude intersect
lines running parallel to the equator
line of the global grid running from the North Pole to the South Pole through Greenwich, England; starting point for measuring degrees of east and west longitude
opposite the Prime Meridian; east and west longitude meet here
Earth is divided into 24 of these zones, each about fifteen degrees of longitude wide and exactly one hour different from the zones on either side of it.
International Date Line
located at the 180* meridian and where the calendar dates begin and end at midnight.
made when points and lines on the globe's surface are trnsferred onto paper; all projections distort the shapes of landmasses.
used mainly on ships and project lines of longitude parallel to each other, resulting in area distortions but correct continent shapes
keeps lines of latitude parallel and lines of longitude curved, resulting in less distortion near the poles.
made by projecting points and lines from a globe onto a cone and are useful for relatively small middle-latitude regions.
models the changes in Earth's surface elevation
line on a map that connects points of equal elevation
contours are marked with their elevation
is the relationship between the distances on the map and the distances on Earth's surface.
explains symbols used on a map
includes maps that have the same dimensions of latitude and longitude.
show the arrangement of rocks at the Earth's surface; computers can generate three-dimensional views of Earth's surface features.
allows scientists to collect information about the Earth often using satellites.
takes pictures of Earth's surface using different wavelengths of light.
global positioning system
also known as a GPS, it uses twenty-four satellites sending position and time signals to allow a person to calculate his or her exact position.
