Philippine plate is the tectonic plate that lies between the Asiatic and Pacific Plate.

The Arctic Ridge has the slowest rate (less than 2.5 cm/yr), and the East Pacific Rise near Easter Island, in the South Pacific about 3,400 km west of Chile, has the fastest rate (more than 15 cm/yr).

Tillite: It is a sedimentary rock formed out of deposits of glaciers.

The radiometric dating methods developed in the recent period have facilitated correlating the rock formation from different continents across the vast ocean. 

Arthur Holmes in the 1930s discussed the possibility of convection currents operating in the mantle portion. These currents are generated due to radioactive elements causing thermal differences in the mantle portion.

The ocean floor may be segmented into three major divisions based on the depth as well as the forms of relief. These divisions are continental margins, deep-sea basins, and mid-ocean ridges.

It also shows the position of the Indian subcontinent and the Eurasian plate. About 140 million years before the present, the subcontinent was located as south as 50°S. latitude.

The Suez Canal is considered the largest man-made canal in the world in terms of its overall length and capacity.
