Definition of hydrology:
The study of water in all its forms
(rain, snow and water on the earth’s surface), and
from its origins to all its destinations on the earth
is called hydrology.
Describe the topography of the ocean floor
and compare it to land.
Identify and describe three major
technologies used to study the ocean floor
Identify the composition of Earth’s oceans

Pacific Ocean; it reaches 11,034

The longest trench is the Peru-Chile
Trench, which extends some 5,900
km (about 3,700 miles) along the west
coast of South America. Trenches are
relatively narrow, usually less than

The mid-ocean ridge represents an area
where, in accordance with plate tectonic
theory, lithospheric plates (also called
tectonic plates) move apart and new crust
is created by magma (molten rock)
pushing up from the mantle . The midocean ridge system is an example of a
divergent (rather than a convergent or
transform) plate boundary.
An example: In the Atlantic Ocean, the
mid-ocean ridge is called the Mid-Atlantic
