Briefly describe the differences between abyssal hills (seaknolls), seamounts, and tablemounts
What will be an ideal response?
Abyssal hills, seamounts, and tablemounts are all volcanic features that occur on abyssal plains on the deep-ocean floor. Abyssal hills, also known as seaknolls, are less than 1,000 meters (0.6 miles) tall and are one of the most abundant features on the planet. Seamounts and tablemounts are volcanic peaks that rise more than 1,000 meters above the ocean floor. Seamounts have conical or pointy tops because they never reached the ocean surface. In contrast, tablemounts are flat-topped because at one time they projected above sea level and were eroded due to wind and waves.
