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.

What kind of stones are never found in the ocean?
Hail stones. Gall stones. The Rolling Stones. Tombstones. Kidney stones.
Why can't photosynthetic organisms grow in the deep water zone?
Photosynthetic organisms need light in order to survive. In very deep water there is no light.
Salt water is obtained by dissolving sodium chloride in water.
Do coconut trees use salt water or fresh water?
Coconut trees prefer to grow in soils that are well-drained and not saline. Although they can tolerate some exposure to salt water, they primarily rely on fresh water for optimal growth and fruit production.
What are the effects of being an archipelago?
terrorism takes place
bandits come to our country
more crimes committed
less security
can be used for human traficking
used for prohibited drugs
What is a coastal inlet or bay called where fresh water mixes with salt water?
A coastal inlet or bay where fresh water mixes with salt water is called an estuary. Estuaries are important ecosystems that support a diverse array of plant and animal species due to the mix of freshwater and saltwater conditions.
The area of calm at the equator is called?
The Doldrums are from the equator to about 10o north and south of it. The Doldrums should not be confused with the Horse Latitudes which are about 30o north and south of the equator.
When are ocean waves dangerous?
When the get really big; these are called Rogue Waves: this phenomenon occurs when the Wave Actions Combine.
Describe the oceans and explain how the water cycle affects the salinity of the ocean?
Oceans are big water bodies. Salinity is due to the presence of minerals in water.
Are there any famous scientists who have worked on hydropower energy?
Yes, one famous scientist who worked on hydropower energy is James B. Francis, an American engineer known for his work on hydraulic engineering and the development of the Francis turbine, a widely used water turbine in hydropower plants. Another notable figure is Nikola Tesla, who explored the potential of hydroelectricity in the late 19th and early 20th centuries.
What effects does the surface-wind pattern have on the circulation of the oceans?
The movement of wind over the surface of the ocean causes friction. The wind drags the ocean surface with it, making the pattern called surface-ocean wind-drift currents.

How are waves formed and how do they shape coastal areas?
Waves are formed by wind blowing across the surface of the water, creating ripples that develop into waves. When waves approach the shore, they interact with the coastline, shaping it through erosion and deposition. Stronger waves can erode cliffs and create sea caves, while deposition of sediment from waves can form beaches and sandbars.
Should you use salt water to mix concrete?
It is not recommended to use salt water to mix concrete as it can cause corrosion of metal reinforcements within the concrete, leading to structural issues over time. It is best to use fresh water for mixing concrete.
At the low and middle latitudes, the SOFAR channel axis lies between 600-1200 meters below the sea surface. It is deepest in the subtropics, and it comes to the surface in high latitudes, where the sound propagates in the surface layer.
- salt is dissolved from the earth (also as ions Na+ and Cl-) and transported in oceans by rivers
- chlorine from volcanic activity in oceans and sodium from the earth form NaCl
Why are resources distributed unequally over the Earth?
Resources are distributed unequally over the earth because of the different natural conditions, level of development and technological levels.
Why does cold water hold more oxygen?
The solubility of oxygen in water is temperature-dependent, and about twice as much (14.6 mg·L−1) dissolves at 0 °C than at 20 °C. To illustrate, recall bubbles forming in a pot of water right before it begins to boil; these bubbles are oxygen that was dissolved at room temperature, but is being ejected as the temperature rises. Oxygen can slip into the crevasses or “holes” that exist in the loose hydrogen-bonded network of water molecules without forcing them apart. A very physical perspective on solubility of oxygen in water is that when the water is colder, the water molecules move less, and the oxygen remains trapped in the aqueous solution.
The mantle is a part of a terrestrial planet or other rocky body large enough to have differentiation by density. The interior of the Earth, similar to the other terrestrial planets, is chemically divided into layers. The mantle is a highly viscous layer between the crust and theouter core. Earth's mantle is a rocky shell about 2,890 km (1,800 mi) thick[1] that constitutes about 84 percent of Earth's volume.[2] It is predominantly solid and encloses the iron-rich hot core, which occupies about 15 percent of Earth's volume.[2][3] Past episodes of melting and volcanism at the shallower levels of the mantle have produced a thin crust of crystallized melt products near the surface, upon which we live.[4] The gases evolved during the melting of Earth's mantle have a large effect on the composition and abundance ofEarth's atmosphere.[citation needed] Information about structure and composition of the mantle either result from geophysical investigation or from direct geoscientific analyses on Earth mantle derived xenoliths.
Two main zones are distinguished in the upper mantle: the inner asthenosphere composed of flowing rock in the state of plasticity, about 200 km thick,[5] and the lowermost part of the lithosphere, composed of rigid rock, about 50 to 120 km thick.[6] A thin crust, the upper part of the lithosphere, surrounds the mantle and is about 5 to 75 km thick.[7]
