Hydrology
Ocean Features
Mid-Ocean-Ridge
A mid-ocean ridge is an underwater mountain system formed by plate tectonics. It consists of various mountains linked in chains, typically having a valley known as a rift running along its spine.
Volcanic Island
Another type of mountain in the sea is an island. It rises from the sea floor, but reaches above the ocean’s surface, sometimes just barely. An island is a solitary mountain formed by volcanic activity.
Seamounts Mountains
A seamount is a mountain rising from the ocean seafloor that does not reach to the water's surface (sea level), and thus is not an island,
Continental Shelf
The area of seabed around a large landmass where the sea is relatively shallow compared with the open ocean. The continental shelf is geologically part of the continental crust.
Abyssal Plain
Flat is almost an understatement. The abyssal plains are some of the flattest features on the planet. Some drop in elevation less than a foot for every 1,000 feet in distance. And are between the continental rise
Ocean Trench
The heavier oceanic plate subducts beneath the lighter continental plate forming a trench. Two oceanic plates converging forming.
Continental Slope
Begins at the continental shelf the most depth part of the ocean floor. It is also in the continental tectonic plates or on the continent part.
Rift Valley
A long, narrow valley that forms as tectonic plates spread. Found near a mid-ocean -ridge. Formed in ocean tectonic plates.
Continental Rise
The gently sloping section of the continental margin or area of the continental plate. it is several miles long and under the continental slope

Water Cycle
the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.
evaporation
Evaporation is a type of vaporization, that occurs on the surface of a liquid as it changes into the gaseous phase.
Precipitation
Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail.
Infiltration
Infiltration is the process by which water on the ground surface enters the soil. Infiltration rate in soil science is a measure of the rate at which soil is able to absorb rainfall or irrigation.
-
Runoff
the draining away of water (or substances carried in it) from the surface of an area of land, a building or structure, etc.
Transpiration
Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.

Water Distribution
Fresh Water
This is less denser then fresh water and the salinity level is much less. The pressure is less than salt water
-
-
-
Salt Water
This water is more dense and it is saltier. The pressure gets higher as deeper as you go. every thing increases as you go down but temperature it decreases.
-
Water is distributed across earth. Most water in the Earth's atmosphere and crust comes from the world ocean's saline seawater, while freshwater accounts for only #% of the total.

Waves , Tides & Currents
Tides
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of Earth.
Currents
a body of water or air moving in a definite direction, especially through a surrounding body of water or air in which there is less movement.
Waves
are surface waves that occur on the free surface of bodies of water (like oceans, seas, lakes, rivers, canals, puddles or ponds). They result from the wind blowing over an area of fluid surface.

Salinity
the concentration of dissolved salts in water etc., usually expressed in parts per thousand by weight.
