Oceans
The amount of earths water stored in the oceans
What is 97%
There are 3 repeating segments that are found in rivers
What are pools, riffles, and runs?
Lakes, rivers, oceans, atmosphere, ice, and even organisms are what in the hydrological cycle
What are reservoirs
The topmost zone of the ocean, from the surface to 200m deep
What is the Epipelagic zone?
Naturally occurring in only one geographical region
Endemic
The oceans occupy this percent of earth's surface
What is 70%
A channel in part of a river system that only contains water during floods
What is an active channel?
Water evaporates from oceans, lakes and rivers to create clouds
What is evaporation
The shallow shoreline affected by tides
What is the intertidal zone?
The layering of the water column by temperatre
What is thermal stratification?
A natural occurrence that drives currents in the oceans
What is wind
The number of layers a river can be divided into
Clouds are moved around the planet by this
What are winds?
The deepest parts of the ocean
What is the hadal zone?
A layer of water through which temperature changes rapidly with depth
What is a thermocline?
Cool, high density, water sinks at the poles, moves along the ocean floor, then rises along land masses
What are deep-water currents?
A theory of river ecology identifying periodic flooding as an essential organizer of river ecosystem structure and function
What is the Flood Pulse Concept?
Water vapor goes through a process to become a cloud
What is condensation?
Light can penetrate the first 10m of the ocean
What is the photic zone
An area in which rivers transition into oceans
Photosynthesis occurs in this oceanic zone
What is the Photic zone?
A model that predicts changes in physical structure, dominant organisms, and ecosystem processes along the length of temperate rivers
The hydrological cycle is powered by this
What is solar energy?
Habitats along the bottom of the ocean
Benthic zone
The transition between the aquatic environment of a river and the upland terrestrial community
What is a riparian zone?
