How Is Thermohaline Circulation Influenced By Salinity And Temperature??

Thermohaline circulation is influenced by changes in density gradients. These density gradients are affected by the salinity and temperature of the ocean’s water. Cold water is denser than warm water and salt water is denser than freshwater. … This causes the water to sink and circulate.

What is thermohaline circulation quizlet?

Thermohaline circulation is a worldwide current system in which the warmer fresher water moves along the surface while the colder saltier water moves beneath it.

How can alternative practices lead to a reduced impact on waterways A alternative practices will completely eliminate changes to waterways?

Alternative practices can completely reverse the damage already done to waterways. … Alternative practices can lead to a decrease in pollution erosion and damage to waterways.

Which of the following practices could help reduce erosion of water banks?

Answer: The practices that could help the reduction of erosion of water banks are maintaining buffer strips.

Which of the following is an effect of fossil fuel emission on oceans quizlet?

Flooding on rivers is caused by human activity rather than natural events. Which of the following is an effect of fossil fuel emission on oceans? … It causes river channels to change shape.

How are temperature and salinity related in a thermohaline circulation pattern quizlet?

thermohaline circulation- vertical circulation caused by changes in density driven by variations in temperature and salinity. … As the salinity increases the density increases as the temperature increases the density decreases.

What is the role of thermohaline circulation?

Thermohaline circulation plays an important role in supplying heat to the polar regions. Therefore it influences the rate of sea ice formation near the poles which in turn affects other aspects of the climate system (such as the albedo and thus solar heating at high latitudes).

How flooding affects rivers and how flooding can be influenced by human activity?

Explain how flooding affects rivers and how flooding can be influenced by human activity. Flooding causes changes to the shape of rivers by eroding the river’s channels. … Flooding also causes changes to floodplains as sediments are deposited in floodplains during flooding.

How does pollution affect marine life a pollution causes a decrease in phytoplankton populations and therefore a decrease in the occurrence of algal blooms?

Pollution from fertilizers can cause an increase in phytoplankton which can result in the formation of algal blooms. Pollution can damage coral reefs which are vital to many forms of marine life. The introduction of toxic chemicals to ocean water can lead to the death of marine life.

Which of the following is the most serious effect of water pollution for humans?

industries thermal waste following is the most serious effect of water pollution for humans.

How is thermohaline circulation influenced by salinity?

Thermohaline circulation is influenced by changes in density gradients. These density gradients are affected by the salinity and temperature of the ocean’s water. Cold water is denser than warm water and salt water is denser than freshwater. … This causes the water to sink and circulate.

How does the loss of vegetation on shore lines affect waterways a decreased sedimentation?

How does the loss of vegetation on shore lines affect waterways? … Reducing access to waterways will lead to an increase in human impact on waterways.

How does flooding affect rivers cause river bends to be cut off?

Answer: D. It causes river channels to change shape.

How does water pollution affect marine ecosystems?

Ocean pollution comes in many forms but the largest factor affecting the oceans is plastic. … Plastic kills fish birds marine mammals and sea turtles destroys habitats and even affects animals’ mating rituals which can have devastating consequences and can wipe out entire species.

Which of the following is an effect of fossil fuel emissions on oceans?

The process of ocean acidification is surprisingly simple. Carbon dioxide from the burning of fossil fuels accumulates in the atmosphere where it causes global warming. But it also affects our oceans. As carbon dioxide enters the ocean it reacts with sea water to form carbonic acid.

How do wetlands reduce flooding and erosion quizlet?

Wetlands reduce flooding and erosion by filtering water. … Wetlands reduce flooding and erosion by absorbing water and then releasing it slowly.

What directly influences Deepwater currents wind temperature pressure and pressure salinity and wind temperature and salinity?

The answer is Option A. The differences in water temperature and salinity are responsible for deep water or ocean currents. Other inducing factors for water currents are wind cabbeling Coriolis effect and breaking waves.

What are the variations in temperature and salinity that affect deep ocean currents quizlet?

Temperature and salinity values change with depth in seawater (higher salinity and colder temperatures with depth) and rapid changes is temperature and salinity with depth occur in the near-surface layer called the Thermocline and the density of water at the sea surface is typically 1.025 g/mL.

What is thought to be most responsible for the salinity of the oceans?

What is thought to be most responsible for the salinity of the oceans? Chlorine gas combined with sodium from Earth’s rocks.

How do temperature and salinity affect water density?

The warmer the water the more space it takes up and the lower its density. When comparing two samples of water with the same salinity or mass the water sample with the higher temperature will have a greater volume and it will therefore be less dense.

How does thermohaline circulation transport heat?

Thermohaline circulation (THC) is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. … The water in these circuits transport both energy (in the form of heat) and mass (dissolved solids and gases) around the globe.

How does global warming affect thermohaline circulation?

Global warming could potentially cause a thermohaline circulation shutdown and subsequent regional cooling but because Earth will continue to warm as a result of greenhouse gas emissions it would not produce another Ice Age.

How do human activities cause drought and flood?

Humans cause and exacerbate flooding due to urban development destruction of natural wetlands and deforestation. Urban development causes water runoff into streams during heavy rain and this runoff causes higher flood peaks and more frequent floods.

Why does India suffer from floods during monsoons?

India’s agrarian economy depends heavily on monsoon rain. Too little means a drought and too much can cause catastrophic flooding. Extreme rainfall washes away fertile topsoil while droughts deplete groundwater reserves that have been declining rapidly in many parts of the country for years.

How can human activities affect the frequency and impact of natural disasters?

Natural disasters are a naturally occurring event that causes damage to human life but human activity can increase their frequency and intensity. Deforestation is wiping out trees causing increased risk for flooding soil erosion and drought.

How does temperature affect algae growth?

Warmer temperatures prevent water from mixing allowing algae to grow thicker and faster. Warmer water is easier for small organisms to move through and allows algae to float to the surface faster.

How do algal blooms cause a decrease in the population of marine organisms?

Harmful algal blooms sometimes create toxins that are detrimental to fish and other animals. After being consumed by small fish and shellfish these toxins move up the food chain and can impact larger animals like sea lions turtles dolphins birds and manatees.

How does climate change lead to an increase in algal blooms quizlet?

How does climate change lead to an increase in algal blooms? a. Decreased temperatures lead to an increase in phytoplankton growth. … Increased pollution leads to lower levels of nutrients in aquatic ecosystems and therefore an increase in phytoplankton growth.

Which of the following best describes effects of water pollution on aquatic ecosystems?

Which of the following best describes the effects of water pollution on aquatic ecosystems? … It can cause long-term alterations of aquatic ecosystems.

How is water pollution affecting the environment?

The main problem caused by water pollution is the effect it has on aquatic life. Dead fish birds dolphins and many other animals often wind up on beaches killed by pollutants in their habitat. Pollution disrupts the natural food chain as well. Pollutants such as lead and cadmium are eaten by tiny animals.
