Seafloor Features and Mapping the Seafloor | manoa.hawaii.edu ...
WEBThe broad size of the ocean floor, its depth and its combination of extreme conditions (cold, dark, with intense water pressure) all contribute to making its exploration difficult. Early civilizations believed the ocean floor to be a smooth bowl, devoid of features or life.
Introduction to the Ocean Floor | manoa.hawaii.edu…
WEBThe ocean floor covers more than 70 percent of the planet’s surface. Like dry land, the ocean floor has various features including flat plains, sharp mountains, and rugged canyons (Fig. 7.1). However, the lowest point in the world ocean is much deeper than the highest point on land.

The Underwater Geology of the Hawaiian Islands is Just Amazing
WEBIts highest peak is at 10,023 feet, and its crater stretches approximately 7.5 by 2.5 miles. Still, since most of this mountain lies below the ocean, it seems to be much smaller than the Big Island. Measured from the sea floor, however, Haleakala would rise to a height of nearly 30,000 feet!
The Oceanic Crust and Seafloor | manoa.hawaii.edu…
WEBThe oceanic crust is much thinner, ranging from 5 to 10 km thick. The continental crust has an average density of 2.7 g/cm 3 and is composed primarily of felsic rock. Felsic rock is rich in light elements such as silicon, aluminum, oxygen, sodium, and potassium. The presence of these lighter elements is responsible for continental crust being ...
