The groundwater flows through the chalk bedrock, re-emerging lower down the slope in springs. The chalk acts as a temporary reservoir by regulating the amount of water supplied to the springs. This is why many chalk streams in the UK have stable flow regimes that vary only slightly over time.
The fall of water where the stream goes over a sudden drop called a knickpoint; some knickpoints are formed by erosion when water flows over an especially resistant stratum, followed by one less so. The stream expends kinetic energy in "trying" to eliminate the knickpoint. Wetted perimeter
Chalk is so common in Cretaceous marine beds that the Cretaceous Period was named for these deposits. The name Cretaceous was derived from Latin creta, meaning chalk. [10] Some deposits of chalk were formed after the Cretaceous. [11] The Chalk Group is a European stratigraphic unit deposited during the late Cretaceous Period.
The geothermally heated groundwater that flows from thermal springs is greater than human body temperature, usually in the range of 45–50 °C (113–122 °F), but they can be hotter. [6] Those springs with water cooler than body temperature but warmer than air temperature are sometimes referred to as warm springs. [28]
A river is a natural flow of freshwater that flows on or through land towards another body of water downhill. [1] This flow can be into a lake, an ocean, or another river. [1] A stream refers to water that flows in a natural channel, a geographic feature that can contain flowing water. [2] A stream may also be referred to as a watercourse. [2]
A salinity maximum zone is formed, and both riverine and oceanic water flow close to the surface towards this zone. [11] This water is pushed downward and spreads along the bottom in both the seaward and landward direction. The maximum salinity can reach extremely high values and the residence time can be several months.
The verdict when it comes to if Gatorade is hydrating is this: It absolutely does hydrate the body and can even do so more effectively than water. But that doesn’t mean you should drink it ...
A body of frozen water more than 50,000 km 2: Inlet: a body of water, usually seawater, which has characteristics of one or more of the following: bay, cove, estuary, firth, fjord, geo, sea loch, or sound. Kettle (or kettle lake) a shallow, sediment-filled body of water formed by retreating glaciers or draining floodwaters. Kill
