Abyssal hills punctuate the relatively featureless plains. These occur where the sediments is not thick enough to cover the underlying rock completely. Often sediment covered, these hills are usually extinct volcanoes or small formations of rock which were once extruded in molten form.

oceanography, Abyssal Hills: Rising from the flat abyssal plain are abyssal hills less than 3,000 feet high and about 10 times as wide. They are variously formed by volcanism, folding and faulting, and sediment draping over older buried seamounts or hills. ... Geological Oceanography Abyssal Hills...

All of the continents put together do not cover even half the area occupied by the abyssal hills, which dominate 60-70% of our planet's surface. We hear a lot about the endless steppes of Asia and the immensity of the Sahara, but who writes about the earth's dominant geomorphological feature?

Abyssal Hills and Abyssal Plains ... The abyssal hills have relatively low relief as they rise only 75 to 900 meters above the ocean floor. Abyssal hills were formed as oceanic ridge. As the crust moves away from the spreading center, it cools and sinks to a lower depth.

Abyssal hills, the most ubiquitous topographic features on Earth1, are thought to be a product of this faulting2,3. Here we report the results of a self-consistent numerical model of lithospheric formation and stretching that includes spontaneous fault creation.

The analysis is segmented into two sub-studies: analysis of near axis ( < 7 Ma) abyssal hills for each of the three segments, and analysis of temporal variations (-1-29 Ma) in abyssal hill morphology along the southern segment (the only segment that clearly persists over the entire age range sampled).
