What Are The Two Factors That Can Cause The Volume Of Water In The Ocean To Change


What Are The Two Factors That Can Cause The Volume Of Water In The Ocean To Change?

There are two main factors that make ocean water more or less dense: temperature and salinity. Cold salty water is denser than warm fresher water and will sink below the less dense layer. Density is defined as the measure of a material’s mass (e.g. grams) divided by its volume (e.g. milliliters).

What are the 2 factors that can cause the volume of water in the ocean to change?

Causes of sea level change

The total volume of the ocean can change as a result of changes in ocean mass (addition of water to the ocean from the land) or expansion/contraction of the ocean water as it warms/cools.

What factors control water density?

Of the three factors—temperature salinity and pressure—that have an effect on water density temperature changes have the greatest effect. In the ocean the thermocline (a water layer within which temperature decreases rapidly with depth) acts as a density barrier to vertical circulation.

How does water density change with depth?

You can see density increases with increasing depth. The pycnocline are layers of water where the water density changes rapidly with depth. … Less dense water floats on top of more dense water. Given two layers of water with the same salinity the warmer water will float on top of the colder water.

How does the addition of salt affect the density of water?

Adding salt to the water increases the density of the solution because the salt increases the mass without changing the volume very much. When enough salt is added to the water the saltwater solution’s density becomes higher than the egg’s so the egg will then float!

What are the three factors that affect seawater density describe how each factor influences seawater density including which one is the most important?

Salinity temperature and depth all affect the density of seawater. Density is a measure of how tightly a certain amount of matter is packed into a given volume. The more the stuff is packed in the higher the density.

What is the saltiest ocean?

Of the five ocean basins the Atlantic Ocean is the saltiest. On average there is a distinct decrease of salinity near the equator and at both poles although for different reasons. Near the equator the tropics receive the most rain on a consistent basis.

What two factors influence seawater density and which one has a greater influence on surface seawater density?

What two factors influence seawater density? Which one has a greater influence on surface seawater density? Salinity and temperature. Temperature has the greatest influence because variations in surface temperature are greater than salinity variations.

Which of the two factors that influence seawater density has the greater influence?

What two factors influence seawater density? Which one has the greater influence on surface seawater density? Temperature and salinity affect density. Temperature has the greater influence on surface density.

Which two factors of ocean water would have the highest density group of answer choices?

There are two main factors that make ocean water more or less dense than about 1027 kg/m3: the temperature of the water and the salinity of the water. Ocean water gets more dense as temperature goes down. So the colder the water the more dense it is and higher salinity increases the density of seawater.

What causes the movement of deep ocean currents?

In contrast to wind-driven surface currents deep-ocean currents are caused by differences in water density. The process that creates deep currents is called thermohaline circulation—“thermo” referring to temperature and “haline” to saltiness. … This water also cools and sinks keeping a deep current in motion.

How does density affect water circulation?

The colder and saltier the ocean water the denser it is. The greater the density differences between different layers in the water column the greater the mixing and circulation. Density differences in ocean water contribute to a global-scale circulation system also called the global conveyor belt.

What causes the movement of ocean currents?

Ocean currents can be caused by wind density differences in water masses caused by temperature and salinity variations gravity and events such as earthquakes or storms. … These currents move water masses through the deep ocean—taking nutrients oxygen and heat with them.

How does salt affect the volume of water?

When you add table salt (sodium chloride NaCl) to water the salt dissolves into ions Na+ and Cl. The volume increases by a small factor but the mass increases by a bigger factor.

How does volume affect density?

Density and Volume are inversely proportional to each other. … When density increases volume decreases.

How does the addition of salt affect the density of water quizlet?

How do temperature and salinity affect density of seawater? Salinity adds to the mass so the more salinity the denser the water. Lower temperatures make the water more dense.

What are two factors that control the salinity of seawater quizlet?

Evaporation and temperature are the two main factors that control the concentration of salts in seawater.

What are three factors which affect the density of sea water?

The density of seawater is a function of temperature salinity and pressure.

What causes density?

The density of a material varies with temperature and pressure. … Increasing the pressure on an object decreases the volume of the object and thus increases its density. Increasing the temperature of a substance (with a few exceptions) decreases its density by increasing its volume.

Which sea has no salt?

Dead Sea

Dead Sea
Primary outflows None
Catchment area 41 650 km2 (16 080 sq mi)
Basin countries Israel Jordan and Palestine
Max. length 50 km (31 mi) (northern basin only)

Can you swim in the Dead Sea?

There is no such thing as swimming in the Dead Sea. … Fast Facts: The Dead Sea is actually not a sea at all but a lake that’s made up of about 30 percent salt. It is the lowest place on earth at 417 feet below sea level.

Are there 7 seas in the world?

The Seven Seas include the Arctic North Atlantic South Atlantic North Pacific South Pacific Indian and Southern oceans. … In Medieval European literature the phrase referred to the North Sea Baltic Atlantic Mediterranean Black Red and Arabian seas.

What factors influence density in seawater quizlet?

The temperature and salinity of seawater influence its density. Temperature and salinity vary with latitude. Therefore the density of seawater also varies with latitude.

What two factors affect the Pycnocline the most?

The formation of pycnocline is mainly affected by seawater temperature and salinity. Usually when the wind is calm the water temperature decreases as the depth increases.

Which of the following are the factors affecting on the distribution of ocean water?

The factors affecting distribution of ocean temperature are latitude prevailing winds ocean currents and local weather. The factors affecting distribution of ocean temperature are latitude prevailing winds ocean currents and local weather.

Which of the following will cause an increase in water density?

Temperature Affects Density

The density of water can also be affected by temperature. When the same amount of water is heated or cooled its density changes. When the water is heated it expands increasing in volume.

What factors cause salinity to vary from place to place?

So differences in rates of precipitation evaporation river discharge and ice formation play a significant role in regional salinity variations. For example the Baltic Sea has a very low surface salinity of around 10 ppt because it is a mostly enclosed body of water with lots of river input.

What makes water more dense?

Water molecules are made up of oxygen and hydrogen atoms bonded together. Oxygen is heavier and smaller than carbon so a volume of water molecules is heavier than the same volume of oil molecules. This makes water more dense than oil.

Which type of ocean water has the greatest density?

The Pacific has most of the lightest water with densities below 26.0 whereas the Atlantic has most of the densest water between 27.5 and 28.0. Antarctic bottom water is indeed densest for Pacific and Indian oceans but not for the Atlantic which has a lot of similarly dense water.

Where is water of the greatest density formed?

high latitudes

In general the water of the greatest density is formed in high latitudes and because this water sinks and fills all ocean basins the deep and bottom water of all oceans is cold.

What two factors affect the density of ocean water and cause deep currents?

Two major factors determine the density of ocean water: salinity (the amount of salt dissolved in the water) and temperature (Figure 14.16). The more salt that is dissolved in the water the greater its density will be. Temperature also affects density: the colder the temperature the greater the density.

What forces are responsible for the movement of ocean water in currents What forces and factors influence the direction and nature of ocean currents?

These currents are on the ocean’s surface and in its depths flowing both locally and globally. Winds water density and tides all drive ocean currents. Coastal and sea floor features influence their location direction and speed. Earth’s rotation results in the Coriolis effect which also influences ocean currents.

What causes deep ocean currents quizlet?

What causes deep water currents to move? It is caused by temperature and salinity of the water. It is from the surface to 200m deep. It is caused by wind action Earth’s spin and the shape of the continents.

What two factors most affect the density of water?

Factors affecting Water Density

There are two factors which are affecting the density of water namely temperature and purity. In the case of pure water temperature plays a crucial role. The density of water varies with temperature but not in a linear way.
