The water flows in from the lower section of the image and passes on both sides of the large island in the center. River bifurcation (from Latin : furca , fork) occurs when a river (a bifurcating river ) flowing in a single channel separates into two or more separate streams (called distributaries ) which then continue downstream .
The Earth's crust is generally divided into two distinct types, oceanic crust and continental crust, both of which "float" on top of the mantle. [3] cryosphere The totality of water in the solid phase on the Earth's surface, including glaciers; sea, lake, and river ice; snow; and permafrost.
Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...
A polyptych (/ ˈ p ɒ l ɪ p t ɪ k / POL-ip-tik; Greek: poly-"many" and ptychē "fold") is a work of art (usually a panel painting) which is divided into sections, or panels. Some definitions restrict "polyptych" to works with more than three sections: [ 1 ] a diptych is a two-part work of art; a triptych is a three-part work; a tetraptych or ...
The Earth's crust can be divided into two regions: the saturated zone or phreatic zone (e.g., aquifers, aquitards, etc.), where all available spaces are filled with water, and the unsaturated zone (also called the vadose zone), where there are still pockets of air that contain some water, but can be filled with more water.
Descriptively, the deep sea water column is divided into five parts—pelagic zones (from Greek πέλαγος (pélagos), 'open sea')—from the surface to below the floor. The term water column is also commonly used in scuba diving to describe the vertical space through which divers ascend and descend.
The intertidal zone or foreshore is the area above water level at low tide and underwater at high tide; in other words, it is the part of the littoral zone within the tidal range. This area can include several types of habitats with various species of life , such as sea stars , sea urchins , and many species of coral with regional differences ...
First, the colder, denser water typically forms a layer near the bottom, which is called the hypolimnion. Second, normally overlying the hypolimnion is a transition zone known as the metalimnion. Finally, overlying the metalimnion is a surface layer of warmer water with a lower density, called the epilimnion. This typical stratification ...
