What affects chemical composition of seawater?

What affects chemical composition of seawater?

The chemical composition of seawater is influenced by a wide variety of chemical transport mechanisms. Rivers add dissolved and particulate chemicals to the oceanic margins. Physical mixing in the oceans (thermohaline and wind-driven circulation) tends to homogenize the chemical composition of seawater.

What are three factors that affect the chemical composition of seawater?

The most important components of seawater that influence life forms are salinity, temperature, dissolved gases (mostly oxygen and carbon dioxide), nutrients, and pH. Each of these is discussed below along with how it varies (or does not vary) and its influence on marine life.

How do plants and animals work together in the ocean?

Most marine species are part of a food chain. A food chain is a top-to-bottom set of animals and plants. They are connected to each other because those on top eat those below. These food chains come together to form a food web.

What would happen to the composition of ocean water if these animals were to decrease drastically in number?

What would happen to the composition of ocean water if these animals were to decrease drastically in number? salts in ocean water would increase.

What is the chemical properties of ocean water?

Ocean water has a high salinity, which is the amount of salt dissolved in water. Besides the high concentration of sodium chloride, ocean water also contains chemicals, such as magnesium, sulfate, calcium, and potassium, as well as dissolved gases, including nitrogen, oxygen, and carbon dioxide.

What are the factors that influence the ocean chemistry?

Ocean chemistry, also known as marine chemistry, is influenced by plate tectonics and seafloor spreading, turbidity currents, sediments, pH levels, atmospheric constituents, metamorphic activity, and ecology.

Why do you think fishes and sea water animals have not gone dead or dehydrated due to salinity or salt content of the sea water?

Water concentration inside a fish is higher than in the ocean itself because the ocean is so salty. As a result, most saltwater fish constantly lose water through their gills and skin. Because the fish is losing water, it must drink a lot to stay hydrated-but salty seawater is the only water around.

What are animals and plants that are in the Pacific Ocean?

Due to its enormous size, the Pacific Ocean is home to a wide array of marine creatures, some of which are found nowhere else on earth.

• Sea otter.
• Manta ray.
• Elephant seal.
• Fur seal.
• Humpback whale.
• Killer whale.
• Dugong. The dugong feeds primarily on sea grass.
• Penguins. An African penguin in South Africa.

What plants and animals live in the Atlantic Ocean?

Some animals in this region include shrimp, crabs, oysters, right whales, dolphins, loggerhead sea turtles, fish, and manatees. Some plants in this region include seaweed, pennyworts, algae, seagrass, sea oats (along coast), and morning glories (along coast).

How does the chemical composition of the atmosphere affect the ocean?

The chemical composition of the atmosphere also affects that of the ocean. For example, carbon dioxide is absorbed by the ocean and oxygen is released to the atmosphere through the activities of marine plants.

How does the temperature of sea water affect marine organisms?

Seawater temperature affects marine organisms by changing the reaction rates within their cell (s). Although each species has a specific range of temperature at which it can live, the warmer the water gets the faster the reactions and the cooler the water the slower the reactions.

How does the composition of sea water change?

The gases dissolved in sea water are in constant equilibrium with the atmosphere but their relative concentrations depend on each gas’ solubility, which depends also on salinity and temperature. As salinity increases, the amount of gas dissolved decreases because more water molecules are immobilised by the salt ion.

What’s the difference between marine geology and chemical oceanography?

Chemical oceanography has to do with the composition of seawater and the biogeochemical cycles that affect it. Marine geology focuses on the structure, features, and evolution of the ocean basins. Marine ecology, also called biological oceanography, involves the study of the plants and animals of…
