As sunlight passes through seawater, its quality decreases due to absorption and scattering. Water absorbs and scatters light, leading to a decrease in intensity and changes in color. This can affect the visibility and penetration of light in the water column, impacting marine life and ecosystems.
What else can I help you with?
What kind of current forms when more dense seawater moves towards less dense seawater?
A density current forms when denser seawater moves towards less dense seawater. This movement occurs due to differences in temperature and salinity, causing the denser water to sink and flow along the seabed towards less dense seawater. This process helps distribute nutrients and maintain ocean circulation.
Is a dark cloth faded by sunlight a physical change?
Yes, a dark cloth faded by sunlight is a physical change. This is because the structure of the cloth has not been altered, only its color has changed due to exposure to light.
What is the energy change of a solar cell?
A solar cell converts sunlight into electricity through a photovoltaic process, capturing the energy of photons and generating an electrical current. The energy change in a solar cell involves the conversion of solar energy into electrical energy, typically measured in terms of efficiency (%) and power output (watts). The overall energy change is positive, as sunlight is converted into usable electrical power.
What other feature of light other than intensity will also change with distance from the canopy?
The quality of light, such as its color spectrum, will also change as it passes through a canopy and with distance from it. This change is due to absorption and scattering by the leaves, resulting in different wavelengths dominating at various distances.
How does a UV activated shirt change color in response to sunlight exposure?
A UV activated shirt changes color in response to sunlight exposure because the special dye in the fabric reacts to ultraviolet (UV) light. When the shirt is exposed to sunlight, the UV rays cause the dye molecules to change structure, which results in a color change. This process is reversible, meaning the shirt will return to its original color when no longer exposed to UV light.
The zone in which seawater temperatures change rapidly is called the?
thermocline
How do salts get removed from the seawater?
Salts are removed from seawater through a process called desalination. This can be done through various methods such as distillation, reverse osmosis, or electrodialysis. These methods help separate the salts from the water, resulting in fresh water that is suitable for consumption.
Is evaporating steam from sea water reversible?
Yes, the process of evaporating steam from seawater is reversible. When seawater is heated, it turns into steam through evaporation, which can then condense back into liquid water when cooled. This phase change is part of the water cycle and can be repeated multiple times. However, the dissolved salts and impurities in seawater do not evaporate with the water, so the condensed water would be fresh, while the remaining seawater would be saltier.
Is the process of evaporating fresh water from seawater for drinking is an example of a physical change?
Yes, this is a physical change.
Does lichen change color?
Yes, lichen can change color depending on factors such as environmental conditions, exposure to sunlight, and air quality. Some species of lichen are known to change color when they are exposed to pollution or other stressors.
What layer of the ocean experiences a rapid change in density of seawater?
pycnocline
Where do blue bonnet flowers get there food source from?
Blue bonnets are a plant. Plants get their food from converting sunlight into food. They take in CO2 through their leaves and make a chemical change with the sunlight.
Does seawater and freashwater change the way a ship sails?
Yes, but not much. A ship is more buoyant in seawater, and thus less of the hull is in the water (thus less resistance).
Why is sunlight different in California?
Geographical location can change the appearance of sunlight.
How does sunlight change into electricity?
energy
What is fixed quality?
An unchanging or unalterable quality. A quality that is not subject to change.
Why does the shadow change length from morning to afternnon?
The change in shadow length throughout the day is due to the sun's position in the sky. In the morning and late afternoon, when the sun is closer to the horizon, shadows are longer because the sunlight passes through a greater thickness of the atmosphere. At midday, when the sun is directly overhead, shadows are shorter because the sunlight travels a shorter distance through the atmosphere.
