The reasons for the decrease in oxygen levels beneath the epipelagic zone include Biological processes that happen in the epipelagic zone and the Decomposition of organic matter.
The epipelagic zone or the sunlight zone or the euphotic zone of the ocean is the uppermost layer. As the depth of the ocean increases the oxygen levels decrease, this can be explained by the following reasons:
Biological processes in the epipelagic zone:
The epipelagic zone contains huge numbers of algae and phytoplankton. They carry out photosynthesis and convert carbon dioxide and solar energy into organic matter and this process releases huge amounts of oxygen. This is possible in the epipelagic zone because of the availability of sunlight and nutrients.
As the depth of the ocean increases, the sunlight is unable to penetrate into the lower levels. Hence, photosynthesis becomes less common in the lower zones of the ocean decreasing the oxygen levels.
Decomposition of the organic matter in the levels below the epipelagic zone:
As dead organic matter sinks in the zones below, bacteria begin to decompose it. This process breaks the organic matter and consumes oxygen. This process also decreases oxygen levels.
Therefore, A combination of limited photosynthesis and bacterial decomposition of organic matter decreases Oxygen levels below the epipelagic zone.

the doppler effect can reveal the rotation speed of a star by the splitting of the spectral lines. true or false
True. The Doppler effect is a phenomenon that occurs when there is a relative motion between a source emitting waves and an observer receiving them.
In the case of a rotating star, different parts of the star's surface are moving towards or away from the observer at different speeds, causing a shift in the wavelengths of the light emitted by the star. This shift can be observed as a splitting of the spectral lines in the star's spectrum, which provides valuable information about the star's rotation speed. By analyzing the degree of splitting in the spectral lines, astronomers can determine the rotation speed of the star, as well as other properties such as its mass, radius, and composition. Overall, the Doppler effect is a powerful tool for studying the properties and behavior of stars, and it has played a key role in our understanding of the universe.

As the planet warms, the boundaries of climatic zones may change, leading to alterations in precipitation patterns and temperature regimes. This can impact ecosystems, agriculture, and human settlements.
While the overall intensity and frequency of storms are projected to increase due to global warming, individual storms may become more intense, but the statement that they will be weaker is not accurate.
A drop in sea level is not an expected consequence of global warming. On the contrary, rising sea levels due to the melting of ice caps and glaciers, combined with thermal expansion of seawater, are major concerns.
Global warming can potentially disrupt ocean currents, which play a vital role in heat distribution. Changes in temperature and salinity can impact circulation patterns, with consequences for regional climate and marine ecosystems.
