What are the factors affecting salinity of the ocean analyse the horizontal distribution of the salinity across the world?

Factors Affecting Ocean Salinity Wind, also influences salinity of an area by transferring water to other areas. The ocean currents contribute to the salinity variations. Salinity, temperature and density of water are interrelated. Hence, any change in the temperature or density influences the salinity of an area.

What are the factors affecting the temperature of seawater?

The most common factors which are affecting the temperature of the seawater are the rising temperature and salinity. Explanation: The temperature and the salinity are two things that control its density.

What are the factors affecting weathering of rocks?

There are two factors that play in weathering, viz. Temperature and Precipitation. Warm climates affect by chemical weathering while cold climates affect by physical weathering (particularly by frost action).

What are the factors that affect the distribution and diversity of marine plankton?

The influence of various factors on the seasonal appearance of phytoplankton differs significantly, with physical factors (such as temperature and light intensity) being the most important and chemical (DO, pH, salinity, total hardness, EC and nutrient level) being of lesser importance (Reynolds, 1984).

What are the factors that affect zonation?

The intensity of wave action appears to be the major factor influencing zonation, other than tidal variation. Increasing water turbulence extends and elevates the zones, as well as limiting certain species to exposed or protected shores.

What are the factors that cause weathering of rocks?

Weathering can be caused by wind, water, ice, plants, gravity, and changes in temperature. To better understand how the erosion and weathering process works….

What are the major threats affecting terrestrial and aquatic biomes?

Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.

What are the major threats to the environment?

Unprecedented environmental issues are emerging on a global scale such as loss of biodiversity, wetlands, and forests; climate change; depletion of energy resources and ozone layer; waste production; deforestation; soil erosion; population growth; water and air pollution; degradation of the ecosystems; extreme weather …

What are the sources and ill effects of marine pollution?

The increased concentration of chemicals, such as nitrogen and phosphorus, in the coastal ocean promotes the growth of algal blooms, which can be toxic to wildlife and harmful to humans. The negative effects on health and the environment caused by algal blooms hurt local fishing and tourism industries.

What are the threats in to the estuaries?

The health of our estuaries is threatened by coastal development, declining water quality and loss of habitat for native species. Estuaries are impacted by pressures from human activities as well as natural events such as storms and floods.

What are the threats of natural phenomenon on estuaries and intertidal zones?

Over-fishing and habitat loss reduces the amount of fish in the ocean and disrupts the food chain. If there are less fish in the ocean there will be more in estuaries trying to reproduce so there are more of their species. – Boating can damage seagrass, reducing or degrading habitat and disrupting the food chain.

What are the threats to estuaries?

Over-fishing and habitat loss reduces the amount of fish in the ocean and disrupts the food chain. If there are less fish in the ocean there will be more in estuaries trying to reproduce so there are more of their species. – Boating can damage seagrass, reducing or degrading habitat and disrupting the food chain.

What are the three reasons why the intertidal zone is so punishing for the organisms that live there?

Why is the intertidal zone a difficult place to live? Because the animals need to survive the pounding waves, and the sudden changes in water levels and sudden temperature changes.

What are those environmental factors that affect the change conditions of rocks?

Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. 2. Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions.

What are three main challenges of living in estuaries?

Management Conference members have identified seven priority problems in the estuary that are contributing to land loss, habitat modification, the decline in certain animal populations, water quality issues related to fish, shellfish, and humans, and contamination of sediment in the marshes.

What are two factors that trigger vertical migration?

The phenomenon may be advantageous for a number of reasons, most typically to access food and avoid predators. It is triggered by various stimuli, the most prominent being response to changes in light intensity, though evidence suggests that biological clocks are an underlying stimulus as well.

What biotic interactions occur between limpets and seaweed?

Limpets, a type of gastropod, survive off of coralline crust algae, known as Clathromorphum. The relationship between the two is known as mutualism.

What causes neap and spring tides?

Spring tides happen just after every full and new moon, when the sun, moon and earth are in line. That’s when lunar and solar tides line up and reinforce each other, making a bigger total tide. Neap tides occur when the moon is in the first or third quarter – when the sun, earth and moon form a right angle.

What causes the biggest daily changes to the intertidal zone?

Tide. The gravitational pull of the moon and the rotational force of the Earth cause tides to rise and fall across the planet. The species living in coastal areas most affected by changing tides have unique ways of surviving.
