Artificial landforms

An artificial landform is any landform that is man-made. This includes roads,bridges,buildings,dams,ditches, quarries,tunnels,polders,and levees. A polder is a piece of  low land that is surrounded by barriers. A levee, dike, dyke, enbanknmet, floodbank, or stopbank is a wall that regulates water levels. Levees are used mainly to help control flooding.

Lagoons,peninsulas, and volcanoes

A lagoon is a shallow body of water separated from a bigger body of water by barrier islands or reefs. A peninsula is any body of land that is surrounded by water on three sides.  A volcano is a mountain-like structure that has a hole in the top that is filled with hot lava,or melted stone. Volcanoes dig more than 3,000 km deep into the earth. Hot lava can be aywhere from 800 C to 1,100 C.

Beach and seamount

A beach is the place along the shoreline of a body of water. Beaches are made up of sand,mud,rock, shingle,gravel,pebbles,and cobblestones. Beaches typically ocurr by wearing down from the current.A seamount is an underwater mountain that does not reach the water's surface. Seamounts are usually quite deep in the ocean.

Oasis and canyon

An oasis is a place in a desert where there is isolated vegatation. Oases, ( plural of oasis ) are usually located beside rivers or around ponds.Other oases are above underground rivers. Canyons are valleys that are mostly surrounded by cliffs and rock. Canyons usually have rivers running through them.

Waterfalls,caves,and islands

Waterfalls are rivers that lead off of cliffs. Some waterfalls go straight down,while others are broken into parts by rocks that stick out of the cliff. If a waterfall is tall,there will usually be mist at the bottom. A cave is a large opening that leads underground. Caves form naturally from the weathering of rock. Islands,pronounced ilands,are bodies of land that are completley surrounded by water.

Cliffs, lakes,and oceans

Cliffs are the edge of raised land. They are often higher than 50 feet tall. Some cliffs lead into the ocean.Lakes are medim bodies of water. Some lakes are circle or oval shaped,while others are shaped quite odd. Crayfish,minnows,fish,and oyesters live here. There are some saltwater lakes near the ocean. These lakes have crabs and lobsters as well. Lake Eerie,Lake Michagain,Lake Superior,Lake Huron,and Lake Ontario are the five great lakes. Oceans are large saltwater bodies of water. They suround the 7 continents. There are 4 oceans:Pacific,Atlanic,Arctic,and Indian. Fish,coral,lobsters,and crabs live here.

Deserts and Rivers

Deserts are dry places with very little rainfall. Almost every desert is hot and sandy,but there are deserts in Antartica that are cold and snowy.Also,the Saharah desert is very hot,but made of rock. Because of being so hot,very few plants and animals live here. Rivers are long,wide steams of flowing water. Life amount is different depending on the size of the river. Many different kinds of animals live here including crayfish,clams,minnows,and fish.
