The same water in a smaller bucket looks only slightly cyan, [1] and observing the water at close range makes it appear colorless to the naked eye. The intrinsic color of liquid water may be demonstrated by looking at a white light source through a long pipe that is filled with purified water and closed at both ends with a transparent window.
Water at the top of the troposphere, particularly in liquid and solid states, cools as it emits net photons to space. Neighboring gas molecules other than water (e.g. nitrogen) are cooled by passing their heat kinetically to the water. This is why temperatures at the top of the troposphere (known as the tropopause) are about -50 degrees Celsius.
Ocean water can appear red if there is a bloom of a specific kind of phytoplankton causing a discoloration of the sea surface. [22] These events are called " Red tides ." However, not all red tides are harmful, and they are only considered harmful algal blooms if the type of plankton involved contains hazardous toxins. [ 23 ]
Cyan (/ ˈ s aɪ. ə n,-æ n /) [2] [3] [4] is the color between blue and green on the visible spectrum of light. [5] [6] It is evoked by light with a predominant wavelength between 500 and 520 nm, between the wavelengths of green and blue.
Rock flour, or glacial flour, consists of fine-grained, silt-sized particles of rock, generated by mechanical grinding of bedrock by glacial erosion or by artificial grinding to a similar size. Because the material is very small, it becomes suspended in meltwater making the water appear cloudy, which is sometimes known as glacial milk .

A person then dips skewered fruit into the mixture, encasing it in the sugar. Once it dries, it creates a glass-like coating. While tanghulu was popular this year, doctors warned that hot sugar ...
Water clarity is a descriptive term for how deeply visible light penetrates through water. In addition to light penetration, the term water clarity is also often used to describe underwater visibility. Water clarity is one way that humans measure water quality, along with oxygen concentration and the presence or absence of pollutants and algal ...
