Continuous process by which water moves through the living and nonliving parts of the environment.
Process of liquid changing to gas.
Process of gas changing to a liquid.
Water falling to Earth in the form of rain, snow, sleet, or hail.
Process of plants releasing water to the air through their leaves.
Water that flows over the surface of the ground.
The process of water soaking into the ground to recharge groundwater sources.
Water that humans can drink, found in lakes, rivers, ponds, glaciers, and underground. Makes up only 3% of all water.
Layer of rock or sediment that holds water.
Comes from precipitation that soaks into the ground between particles of soil and spaces in layers of rock.
Chemical formula for water
Property of water where molecules on surface stick together causing a tightness, almost giving water a "skin".
A river and all its tributaries together with the watershed.
The land area that supplies water to a river system.
Small stream that feeds a larger river.
Ponds and Lakes
Form when water collects in hollows and low-lying areas of land.
Area of land that is covered with a shallow layer of water during some or all of the year. Three common types are marshes, swamps and bogs.
Area of permeable rock or soil that is totally filled, or saturated with water.
Top of saturated zone.
Layers of rock and soil above the water table that contain air as well as water, not able to be saturated.
largest and deepest of the oceans; larger than all of Earth's continental land mass put together
Half the size of the Pacific, covers about 20% of Earth's surface.
The third largest ocean that is located between India, Africa and the Indonesian Islands.
Surrounds the Antarctic continent and is covered by ice part of the year.
Smallest and shallowest ocean that is located near the North Pole and is also covered by ice part of the year.
Water from a sea or ocean that has an average salinity of 35 ppt (parts per thousand), or one kg of ocean water contains about 35 g of salt.
The shallow area on the edges of a continent beneath the water. It slopes gently and can reach depths of 200 m.
The slope between the continental edge and the deep ocean floor, or abyssal plain. Ranges from 200 m deep to 4,000 m deep.
The base of the continental slope. It's made of piles of sediment.
The relatively flat area between a continental rise and mid-ocean ridge. The abyssal plain covers more than 50% of the Earth's surface. It is covered in mud and the remains of dead organisms. Its average depth is 4,000 m.
A long seismically active ridge in the middle of an ocean basin, such as the Mid-Atlantic Ridge, formed at rift zones.
An underwater mountain.
A piece of land created by volcanic eruptions that rises above sea level. Not all seamounts have enough height to be exposed above sea level.
Huge cracks in the deep ocean basin that occur at subduction zones.
Surface or Sunlit zone
The top 200 meters of the ocean where enough sunlight penetrates for plants to carry on photosynthesis.
200 to 1000 meters deep. A dim zone where some light penetrates, but not enough for plants to grow.
The zones of the ocean greater than 1000 meters deep. No light penetrates to these depths.
Measure of the mass of dissolved solids in a mass of water.
Current on the surface of Earth's oceans caused by WIND.
A disturbance that transfers energy from place to place.
The daily rise and fall of Earth's waters on its coastlines, caused by the gravitational pull of the sun and moon.
Deep Current or Density Currents
Flow in the deep water of the ocean below the surface currents, and are caused by differences in temperature and salinity from one location to another.
The effect of Earth's rotation on the direction of winds and currents.
When surface currents meet continents, the currents are deflected and change direction.
The distance between two corresponding parts of a wave.
The vertical distance from the crest of a wave to the trough.
The number of waves passing a fixed point per second.
