Question

1. explain how temperature affects the distribution of marine species in the ocean.
2. what role does salinity play in the formation of ocean currents?
3. describe the process of coral bleaching and its consequences for marine ecosystems.
4. how do ocean currents influence global climate patterns?
5. what is the relationship between ocean density and the stratification of water layers?
6. identify the main processes that lead to changes in ocean salinity.
7. discuss how tides can impact coastal ecosystems.
8. how do human activities contribute to ocean acidification?
9. explain the concept of thermohaline circulation and its significance.
10. in what ways do oceanic processes, like currents and tides, affect weather systems on land?

Explanation:

1. Temperature affects enzyme - activity and metabolic rates of marine species. Different species have specific temperature - ranges for survival and reproduction, thus influencing their distribution.
2. Salinity affects water density. Higher salinity water is denser. Differences in salinity between ocean regions drive thermohaline circulation, a major component of ocean - current formation.
3. Coral bleaching occurs when corals expel symbiotic algae due to stress (e.g., high water temperatures). This leads to loss of color and can cause coral death, disrupting the marine ecosystem as corals are habitat for many species.
4. Ocean currents transport heat globally. For example, the Gulf Stream warms the western coast of Europe. They also affect precipitation patterns by influencing evaporation and moisture transport.
5. Ocean density is related to temperature and salinity. Higher - density water sinks, creating stratified water layers. This stratification affects nutrient and oxygen distribution.
6. Processes like evaporation increases salinity, while precipitation, river runoff, and sea - ice melting decrease it.
7. Tides can bring in nutrients and oxygen during high - tide, and expose intertidal organisms to air during low - tide, affecting their survival and distribution in coastal ecosystems.
8. Human activities such as burning fossil fuels release carbon dioxide. A significant portion of this CO₂ is absorbed by the ocean, reacting with water to form carbonic acid, leading to ocean acidification.
9. Thermohaline circulation is the global system of density - driven ocean currents. It transports heat, nutrients, and oxygen around the globe, influencing climate patterns.
10. Ocean currents can warm or cool adjacent land areas, affecting air temperature and humidity. Tides can influence coastal winds and the movement of moisture, impacting weather systems on land.

Answer:

1. Temperature influences enzyme - activity and species' survival and reproduction ranges, thus affecting distribution.
2. Salinity differences drive thermohaline circulation, a key part of ocean - current formation.
3. Coral bleaching is expulsion of symbiotic algae due to stress, causing coral death and ecosystem disruption.
4. Ocean currents transport heat and moisture, affecting global climate patterns.
5. Higher - density water sinks, creating stratified water layers.
6. Evaporation increases salinity; precipitation, river runoff, and sea - ice melting decrease it.
7. Tides affect nutrient supply and organism exposure in coastal ecosystems.
8. Human - released CO₂ is absorbed by the ocean, forming carbonic acid and causing acidification.
9. Thermohaline circulation is a global density - driven current system, important for heat and nutrient transport.
10. Ocean currents and tides can affect land air temperature, humidity, and wind patterns.
