Oceanography

Oceanography, also called marine science, is the study of oceans. It includes the study of physical oceanography, marine chemistry, marine geology, and marine biology. Areas covered in oceanography are the shape, depth, and distribution of oceans, and also their composition, life forms, ecology, and water currents, as well as their legal status. If you would like to know more or share your knowledge about oceanography, ask and answer questions here! Includes questions related to the study of Earth's oceans and seas.

How do ocean waves change water to erode land along the shoreline?

Waves are formed by the action(friction) of the wind on the surface of the water. The longer the uninterrupted distance the wind can blow over the surface the larger the waves.This is called the fetch.

T he waves have speed and mass therefore they have energy. This energy can destroy or erode by mechanical action, hydraulic action and chemical action. If the waves are small they can have a constructive action. So waves can be destructive or constructive.

The moon does not form waves. The moon's gravitational influence is responsible for the tides

In a salt solution that is 15 percent salt what percent is water?

It depends, is the solution 15% salt or 15% saturatedwith salt? If it is 15% salt, is is 85% water. If it is 15% saturated, it is 5.385%.

How would you describe Niagara Falls?

Niagara Falls divide into two main waterfalls but three waterfalls in total. 216,000 tons of water flow and fall every second. 75,750 gallons second in the American side and 681,170 gallons on the Canadian side. The huge volume of water, makes silvery mist and if it gets under the light, they may display rainbows. Niagara Falls also produce 4 million kilowatts of electricity in the Cave of the Winds and into 6 hydroelectric plants. 55 percent of electricity on the American side and 45 percent in the Canadian side. In winter the huge amount of water and the mist makes ice along the way, but it never freezes. Niagara Falls extends 17 miles (27 kilometers). At night, beams of colored lights illuminate the falls. Many millions of people come to visit of the attraction it makes.

Contour line below the sea?

Contour lines below the sea show depth levels using lines that connect points of equal depth. The lines are closer together in steep areas and farther apart in flat areas. They help visualize the underwater topography and identify submarine features like trenches, ridges, and seamounts.

In approximately how many hours might a seaside location expierance low tide after high tide?

In general, a seaside location typically experiences low tide around 6 hours after high tide. This timing can vary based on the specific location, weather conditions, and other environmental factors.

What type of volcano is Mt Toba?

Mt. Toba is a supervolcano, which is a type of volcano capable of producing massive eruptions with a Volcanic Explosivity Index (VEI) of 8, the highest level. These types of eruptions are thousands of times more powerful than typical volcanic eruptions.

What is the most powerful surface current in the North Atlantic Ocean?

The Gulf Stream is the most powerful surface current in the North Atlantic Ocean. It transports warm water from the Gulf of Mexico towards Europe, influencing the climate of the region and affecting weather patterns and marine life along its path.

What is the actual movement of a particle being carried by a waveform toward shore?

As the waveform approaches the shore, the particle will experience a circular motion. This is due to the orbital motion of the water particles that make up the wave. In essence, the particle will move in a circular pattern as the wave energy transports it towards the shore.

Why can't the Titanic be salvaged?

The Titanic is located at a depth of about 12,500 feet, making it extremely challenging and costly to reach and salvage. Additionally, the wreck is deteriorating due to corrosion and other natural processes, which further complicates any salvage efforts. The Titanic wreck is also a protected site under international agreements, limiting any attempts to salvage it.

What are abiotic components of a pond?

The abioctic factors of a pond ecosystem are

Water

Rock and

Mud

these are important because you can not have a pond without water and there is always dirt on the ground so the dirt turns to mud and there is always rock in sand.

Why does Europe have a mild climate?

Europe has a mild climate due to the presence of the Gulf Stream, which brings warm water from the Gulf of Mexico to western Europe. This results in warmer temperatures compared to regions at similar latitudes. Additionally, Europe's proximity to the Atlantic Ocean helps regulate its climate, providing moderate temperatures and relatively stable weather patterns.

What is an underwater ridge lying near the surface of the water called?

An underwater ridge near the surface of the water is called a seamount. These are elevated features on the seafloor that do not reach the surface of the water.

What does not affect ocean salinity?

Rainfall does not directly affect ocean salinity, as rainwater is freshwater and dilutes the salt content in the ocean. Other factors such as evaporation, ice formation, and river input can influence ocean salinity levels.

Why fresh water is important for human life than salt water?

Water is elemental for most life on earth. To name some biological processes, that need water: photosynthesis, catabolism and anabolism (how life stores/uses energy), glycolysis, transpiration, and many more

Water is also vitally important to keep temperatures on earth down by transpiration and to enhance mixture in the atmosphere by convection. Also water is a great tool for cleaning and the habitat of many creatures.

Freshwater is now that kind of water that is not polluted by anything (salt, dirt,...) and thus usable for these processes.

What kind of air would be characteristic of a continental polar air mass?

Continental polar masses are cold and dry air masses because the cold air cannot hold much moisture. As they move into warmer air, they can trigger precipitation.

Does the earth's water cycle end when fresh water drains into the oceans?

No. When water is evaporated into the atmosphere, the salt isn't evaporated with it. The water in the water cycle is always fresh water, and when it drains into the oceans it dimply diludes the ocean from having such a high salt content. The water cycle is always continuous and if it ended, we would all die.

Are longshore currents parallel to the shoreline?

Yes, longshore currents flow parallel to the shoreline. They are influenced by the angle of incoming waves and play a significant role in the transport of sediment along coastlines.

What is a beach profile?

The trace of a beach surface, generally starting at the most landward point that mean high tide reaches and extending offshore to the point of storm wave base.

A typical beach profile from it's most landward to it's most seaward position consists of a lagoon, a dune system, backshore, foreshore (beach), upper and lower shoreface, and offshore.

What is slab suction?

Slab suction is the process by which a subducting tectonic plate pulls on the rest of the plate, which can contribute to the motion and deformation of Earth's lithosphere. This pulling force is generated by the sinking of denser oceanic lithosphere beneath less dense continental lithosphere at a convergent plate boundary. The interaction between the subducting slab and the overlying plate can influence various geodynamic processes, such as plate motion, mountain building, and seismic activity.

Oceans beginning with A?

There are two. The Arctic Ocean & The Atlantic Ocean.

What is 3000000000000000?

3000000000000000 is a numerical value that can be expressed as 3 quadrillion in short scale or 3 billiard in long scale.

Which sea creatures does Sylvia Earle study?

Sylvia Earle studies various sea creatures, but she is particularly known for her work with sharks, jellyfish, and deep-sea creatures. She has spent a significant amount of time exploring and researching these animals to better understand their behavior and importance in marine ecosystems.

How were the oceans created?

The first oceans began to form around 4 billion years ago. They formed from the outgassing of water vapor from volcanoes as well as water transported to the surface via asteroids and comets. As the Earth cooled water vapor in the atmosphere turned into clouds which rained down the water that would create the oceans.

What is the worldwide current turner?

The current turnover worldwide is constantly changing due to various factors such as economic conditions, consumer behavior, and industry trends. As of the latest available data, global turnover across all industries is estimated to be in the trillions of dollars.

How long ago were the oceans created?

The earth formed around 4.2 billion years ago, but it would have been too hot for water to liquidize at that point.

I think around 3.8 billion years ago, but this is easy to look up online.
