LandformsLandforms

PlainsPlains• large, flat areas which often have thick,

fertile soils and grassy meadows

Coastal PlainsCoastal Plains

• stretch along coastal areas and are often called lowlands

Interior PlainsInterior Plains • in the central part of a continent

• GREAT PLAINS - USA

PlateausPlateaus • flat, raised, areas of land made up of nearly horizontal rocks

• their edge rises steeply from the area around them

MountainsMountains • tower above the surrounding land

Folded MountainsFolded Mountains • form when rock layers are squeezed from opposite sides, causing the rock layers to fold like a rug pushed up against the wall

Upwarped mountainsUpwarped mountains• forces inside the Earth push the crust up

Fault-Block MountainsFault-Block Mountains • form when tilted blocks of rock are separated by faults from the surrounding rock

FaultFault• boundary where 2 BLOCKS OF

BEDROCK MEET. FAULTS MAY SHOW ON THE SURFACE!

Volcanic MountainsVolcanic Mountains • layers of molten material pile up forming a cone-shape

Section II - ViewpointsSection II - Viewpoints

• Latitude and longitude lines identify exact locations on Earth by means of an imaginary grid system

• WHEN STATING A LOCATION LATITUDE ALWAYS COMES BEFORE LONGITUDE

LatitudeLatitude

• lines run parallel to the equator

• Running from the North Pole through Grennwich Observatory near London, England, the prime meridian is the reference point for lines of longitude

• distances in degrees east or west

• East lines of longitude meet west lines of longitude at the 180° meridian, which is opposite the prime meridian

• They also meet at the poles!!!

• Earth is divided into 24 time zones, each about 15 degrees of longitude wide and exactly one hour different from the zones on either side of it.

• Calendar dates begin and end at midnight

• the International Date Line is located near the 180° meridian
