  2. Caloric reflex test - Wikipedia

    en.wikipedia.org/wiki/Caloric_reflex_test

    Hot and cold water produce currents in opposite directions and therefore a horizontal nystagmus in opposite directions. [4] In patients with an intact brainstem: If the water is warm (44 °C or above) endolymph in the ipsilateral horizontal canal rises, causing an increased rate of firing in the vestibular afferent nerve.

  3. Thermocline - Wikipedia

    en.wikipedia.org/wiki/Thermocline

    The warm layer is called the epilimnion and the cold layer is called the hypolimnion. Because the warm water is exposed to the sun during the day, a stable system exists and very little mixing of warm water and cold water occurs, particularly in calm weather.

  4. Mpemba effect - Wikipedia

    en.wikipedia.org/wiki/Mpemba_effect

    The phenomenon, when taken to mean "hot water freezes faster than cold", is difficult to reproduce or confirm because it is ill-defined. [4] Monwhea Jeng proposed a more precise wording: "There exists a set of initial parameters, and a pair of temperatures, such that given two bodies of water identical in these parameters, and differing only in initial uniform temperatures, the hot one will ...

  5. Ikogosi Warm Springs - Wikipedia

    en.wikipedia.org/wiki/Ikogosi_Warm_Springs

    The Ikogosi Warm Springs is a tourist attraction located at Ikogosi, a town in Ekiti State, southwestern Nigeria. [1] Flowing abreast the warm spring is another cold spring which meets the warm spring at a confluence, each maintaining its thermal properties. [2] These attributes make the spring a tourist attraction in Nigeria. [3]

  6. Lake stratification - Wikipedia

    en.wikipedia.org/wiki/Lake_stratification

    Lake stratification is the tendency of lakes to form separate and distinct thermal layers during warm weather. Typically stratified lakes show three distinct layers: the epilimnion, comprising the top warm layer; the thermocline (or metalimnion), the middle layer, whose depth may change throughout the day; and the colder hypolimnion, extending to the floor of the lake.

  7. Ocean stratification - Wikipedia

    en.wikipedia.org/wiki/Ocean_stratification

    Ocean stratification is the natural separation of an ocean's water into horizontal layers by density.This is generally stable stratification, because warm water floats on top of cold water, and heating is mostly from the sun, which reinforces that arrangement.

  8. Stratification (water) - Wikipedia

    en.wikipedia.org/wiki/Stratification_(water)

    The thermal stratification of lakes is a vertical isolation of parts of the water body from mixing caused by variation in the temperature at different depths in the lake, and is due to the density of water varying with temperature. [14] Cold water is denser than warm water of the same salinity, and the epilimnion generally consists of water ...

  9. Ocean current - Wikipedia

    en.wikipedia.org/wiki/Ocean_current

    Alaska Current – Warm-water current flowing nortwards along the coast of British Columbia and the Alaska Panhandle; Aleutian Current – Eastward-flowing ocean current which lies north of the North Pacific Current; California Current – Pacific Ocean current; Cape Horn Current – Cold water current that flows west-to-east around Cape Horn
