Why does deep water appear green?

Answer: The colours having longer wavelength are absorbed by water than those having shorter wavelengths. Red, orange, yellow, and green having longer wavelengths are absorbed by water molecules quickly when sunlight hits water. Thus, we can see water in blue colour in the deep sea.

What is the average density of ocean water is it more or less dense than fresh water?

) ions). Average density at the surface is 1.025 kg/l. Seawater is denser than both fresh water and pure water (density 1.0 kg/l at 4 °C (39 °F)) because the dissolved salts increase the mass by a larger proportion than the volume.

What are 3 physical or chemical properties of salt water?

The physical properties of seawater–temperature, salinity, pressure, density, and related quantities such as potential density, heat capacity, sound speed, and others–are of fundamental importance to physical oceanography.

What chemical properties of ocean water make it a possible source of energy?

Because seawater is salty, containing 60 to 100 times more ions than freshwater, it increases the electrical potential, or voltage, between the two electrodes. That makes it possible to reap far more electricity than the amount used to charge the battery.

Why is deep water blue?

The ocean acts like a sunlight filter. The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. Hardly any light penetrates deeper than 656 feet , and no light penetrates deeper than 3,280 feet .

Why do we see bluish color of water in deep sea?

Generally, water molecules absorb sunlight and scatter colours. These colours are not absorbed but scattered by water. Thus, we can see water in blue colour in the deep sea. Since blue colour of deep sea is mainly due to scattering, the correct answer is option (C) Scattering of light.

What are the chemical and physical properties of seawater?

Chemical and physical properties of seawater The six most abundant ions of seawater are chloride (Cl−), sodium (Na+), sulfate (SO24−), magnesium (Mg2+), calcium (Ca2+), and potassium (K+). By weight these ions make up about 99 percent of all sea salts.

What are the properties of sea water?

Seawater has unique properties: it is saline, its freezing point is slightly lower than fresh water, its density is slightly higher, its electrical conductivity is much higher, and it is slightly basic.

What makes up sea water?

Seawater is a complex mixture of 96.5 percent water, 2.5 percent salts, and smaller amounts of other substances, including dissolved inorganic and organic materials, particulates, and a few atmospheric gases. Much of the world’s magnesium is recovered from seawater, as are large quantities of bromine.

Why are deep seas and oceans blue?

The ocean acts like a sunlight filter. The ocean is blue because water absorbs colors in the red part of the light spectrum. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water. Most of the ocean, however, is completely dark.

What conditions exist for life in the deep ocean?

What conditions exist for life in the deep ocean? Organisms living in the deep ocean must be adapted to survive under extreme pressure, limited light, cold temperatures, and other factors. Organisms living in the deep ocean must survive in a physical environment that is radically different from ocean habitats near the sea surface.

Why is there no light in the deep ocean?

Light is virtually absent in the deep ocean, which means that deep-sea organisms cannot rely on vision for feeding, avoiding being eaten, or mating.

How does the deep ocean differ from other places on Earth?

The conditions in the deep ocean are vastly different – and arguably more extreme – than those found in more shallow ocean waters, making these habitats different from other places on Earth.
