Introduction

Land forms are the natural shapes or features called landforms.

There are many different types of landforms found on the Earth.

Plains

An extensive level, usually treeless area of land on Earth’s surface

A natural elevation of the Earth’s surface having considerable mass, generally steep sides.

Mountain

Fold MountainsFold mountains are the most common type of mountain. The world’s largest mountain ranges are fold mountains. These ranges were formed over millions of years.Fold mountains are formed when two plates collide head on, and their edges crumbled, much the same way as a piece of paper folds when pushed together.

Block Mountains

Instead of the earth folding over, the earth's crust fractures (pulls apart). It breaks up into blocks or chunks. Sometimes these blocks of rock move up and down, as they move apart and blocks of rock end up being stacked on one another.

Volcanic Mountains

Volcanic Mountains are formed when molten rock (magma) deep within the earth, erupts, and piles upon the surface. Magna is called lava when it breaks through the earth's crust. When the ash and lava cools, it builds a cone of rock. Rock and lava pile up, layer on top of layer.

River

A large natural stream of water emptying into an ocean, lake, or other body of water and usually fed along its course by converging tributaries.

Plateau

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. Plateaus form either when mountains get worn down and their tops are not as jagged or when a large portion of flat earth is pushed up from the earth.
