Cliffs form through tectonic activity, water movement, weathering, erosion and glacier activity. Earthquakes and landslides also form cliffs. Cliffs tend to form on coasts, in mountainous areas, along rivers or as the wa... More »

River cliffs are also known as cut banks or river-cut cliffs. A river cliff is formed on the outer edge of a stream bend when a fast-flowing water source erodes the surface. River cliffs are constantly undergoing erosion... More »

The arctic lowlands consist of several barren low-lying islands with coastlines dominated by sheer, towering cliffs and frigid surrounding waters of the Atlantic that contain pieces of massive ice sheets. Together, the l... More »

Canyons are formed by wind and water erosion over a long period of time after a large hill, mountain or plateau is formed. The original land mass is formed by tectonic plates colliding and causing tectonic uplift, and th... More »

Landforms are divided into 11 major categories: Aeolian, coastal and oceanic, erosion, fluvial, impact, karst, lacustrine, mountain and glacial, slope, tectonic and volcanic. Within these groupings are many landform subt... More »

The Grand Canyon was formed primarily by erosion from the constant water flow of the Colorado River. This erosion occurred gradually over the past 5 to 6 million years. More »

When a volcano surfaces just above sea level, erosion from waves can create a plateau called a guyot, that eventually sinks below sea level. Guyots sinks as a result of both erosion and the tectonic plates that the ocean... More »
