How Do Abyssal Plains Form. Web abyssal hills are formed by stretching of the oceanic lithosphere. As the plates move apart, the ocean floor splits and cracks.

In fact, the abyssal plains are likely the most level areas on the earth. These submarine surfaces vary in depth only from 10 to 100 cm per kilometre of horizontal distance. Like most topographic features of the earth, abyssal plains are formed due to tectonic plate movement. Abyssal plains covering a major portion of ocean floor between the depth of 3000m to 6000m. Web abyssal plains are made up of silt, sediment and sand that blankets the original ocean floor, forming a smooth, flat plain. Web abyssal hills are formed by stretching of the oceanic lithosphere. Consumption or destruction of the oceanic lithosphere occurs at oceanic trenches (a type of convergent boundary, also known as a destructive plate boundary) by a process known as subduction. As the plates move apart, the ocean floor splits and cracks. The plain is generally 13,000 to 20,000 ft (4,000 to 6,000 m), Much of this sediment is deposited by turbidity currents that have been channelled from the continental margins along submarine canyons into deeper water.
Abyssal plains covering a major portion of ocean floor between the depth of 3000m to 6000m. As the plates move apart, the ocean floor splits and cracks. Web abyssal plains are made up of silt, sediment and sand that blankets the original ocean floor, forming a smooth, flat plain. It forms when seafloor spreading creates new crust, the new crust pushes the older crust away creating a plain like area in the water. These submarine surfaces vary in depth only from 10 to 100 cm per kilometre of horizontal distance. The plain is generally 13,000 to 20,000 ft (4,000 to 6,000 m), Abyssal plains covering a major portion of ocean floor between the depth of 3000m to 6000m. Abyssal plains are extremely flat and featureless plains of the deep ocean floor. Irregular in outline but generally elongate along continental margins, the larger plains are hundreds of. Consumption or destruction of the oceanic lithosphere occurs at oceanic trenches (a type of convergent boundary, also known as a destructive plate boundary) by a process known as subduction. In fact, the abyssal plains are likely the most level areas on the earth.
