Shahid Bin Shajahan 4 BProject: GeographyLANDFORMS : Shahid Bin Shajahan 4 BProject: GeographyLANDFORMS How are Landforms Made?
Some landforms are created by the action of wind, water, and ice. This action physically changes the Earth’s surface by carving and eroding land surfaces, carrying and depositing soil, sand and other debris.
Crustal movement and other tectonic activity inside Earth create landforms; mountains, faults, sinks, and volcanoes.

Slide 3 : Creeks Dubai Creek overlooking the Rigga Al Buteen area of Deira CREEK:
A Narrow inlet of water on the sea shore or in a river bank.
How it Benefitted to us:
*They are natural harbour

Example: Arabian Gulf, Coral and Gulf of Oman
Benefits:
Setting up ports and Sea Ports
Mountains : Mountains Image of Mountain A Mountain is a mass of very high land going up to a Peak.
Mountains like these in Alaska. Alaska has many mountain ranges. These mountains are "young." You can tell because they still have sharp peaks.

Difference of Plateaus and Mountains:Plateaus are raised areas of land with a flatter top. It differs from a mountain in that a mountain has a jagged peak at the top. : Difference of Plateaus and Mountains:Plateaus are raised areas of land with a flatter top.

Slide 23 : DEFINICATIONS OF LAND FORMS
A mountain pass. continentThe land mass on Earth is divided into continents. The seven current continents are Africa, Antarctica, Asia, Australia, Europe, North America, and South America. coveA cove is small, horseshoe-shaped body of water along the coast; the water is surrounded by land formed of soft rock. deltaA delta is a low, watery land formed at the mouth of a river. It is formed from the silt, sand and small rocks that flow downstream in the river and are deposited in the delta. A delta is often (but not always) shaped like a triangle (hence its name, delta, a Greek letter that is shaped like a triangle). desertA desert is a very dry area. duneA dune is a hill or a ridge made of sand. Dunes are shaped by the wind, and change all the time.
riverA river is a large, flowing body of water that usually empties into a sea or ocean.
Slide 24 : Definitions:archipelagoAn archipelago is a group or chain of islands clustered together in a sea or ocean. atollAn atoll is a ring (or partial ring) of coral that forms an island in an ocean or sea. The coral sits atop a submerged volcanic cone. bayA bay is a body of water that is partly enclosed by land (and is usually smaller than a gulf). butteA butte is a flat-topped rock or hill formation with steep sides.
islandAn island is a piece of land that is surrounded by water.
Slide 25 : lakeA lake is a large body of water surrounded by land on all sides. Really huge lakes are often called seas. latitudeLatitude is the angular distance north or south from the equator to a particular location. The equator has a latitude of zero degrees. The North Pole has a latitude of 90 degrees North; the South Pole has a latitude of 90 degrees South. longitudeLongitude is the angular distance east or west from the north-south line that passes through Greenwich, England, to a particular location. Greenwich, England has a longitude of zero degrees. The farther east or west of Greenwich you are, the greater your longitude. Midway Islands (in the Pacific Ocean) have a longitude of 180 degrees (they are on the opposite side of the globe from Greenwich).
seaA sea is a large body of salty water that is often connected to an ocean. A sea may be partly or completely surrounded by land.
Slide 26 : surface runoffSurface runoff is water flow on the land that occurs when the soil is saturated with water and the excess water (from precipitation or snowmelt) runs over the surface. waterfallWhen a river falls off steeply, there is a waterfall. wetlandA wetland is an area of land that is often wet; the soil in wetlands are often low in oxygen. Wetland plants are adapted to life in wet soil. There are many types of wetlands, including: swamp, slough, fen, bog, marsh, moor, muskeg, peatland, bottomland, delmarva, mire, wet meadow, riparian, etc.
