Abyssal plains are large, flat features that cover about ________ of the planet.
spin [16.1K]

Abyssal plains are large, flat features that cover about one third of the planet.

<h3>What are Abyssal plains?</h3>
  • The broad, flat, sediment-covered regions of the deep ocean floor are known as abyssal plains.
  • They have a slope of less than one foot of height variation for every thousand feet of travel, making them the flattest, featureless places on Earth.
  • When tectonic plates separate, magma rises and forms new crust, filling the space that was left between the plates.
  • When sediments from the shoreline pass over the continental shelf, tumble down the continental slope, and deposit on top of the more recent oceanic crust, they create an abyssal plane.
