Evaporation
liquid water to water vapor by heating
Condensation
water vapor to liquid water by cooling
Precipitation
water returning to earth's surface through rain, hail, snow, or sleet
Transpiration
water from plants evaporating
Run off
water that flows along the ground returning to rivers, ponds, lakes, and oceans.
Ground Water
the water that gets absorbed and collect by the ground
Collection
places where water collects and then gets evaporated. Includes lakes, ponds, seas, and oceans.
Water Vapor
the gaseous form of water
Infiltration
Water seeping into the soil
Seamount
a mountain which forms underwater on the sea floor
Mid-ocean ridge
underwater mountain chain which forms when plates divide
Ocean trench
deepest part of the ocean; very high pressure and very cold
Continental rise
forms at the bottom of a continental slope; sediment is deposited and builds up
Currents
ocean water moving in a definite and consistent pattern
Gulf Stream
brings warm water to the British Isles; makes it a mild climate
Surface currents
currents which occur on the ocean's surface; caused by wind
Coriolis effect
causes ocean currents to "curve"; caused by Earth's rotation
Continental deflection
when currents run into the continents, they change directions
Deep currents
currents created by density differences (cool temperatures and high salinity)
Neap tide
Spring tide
Creates an exceptionally high tide and an exceptionally low tide
Spring tides
Has a very small tidal range
Neap tide
Tides
the falling and rising of water due to the gravitational pull of the moon and the sun on Earth's oceans
Point source pollution
ocean pollution which comes from one source (oil spills, sludge dumping are examples)
Non-point source pollution
pollution which reaches the oceans by runoff (lawn fertilizer, motor oil are examples)
Crest
highest point of a wave
Trough
lowest point of a wave
Sodium and chlorine
Two most abundant elements in ocean water, makes oceans salty
Atmosphere
where most condensation takes place
