Seawater has many different gases dissolved in it, specially nitrogen, carbon dioxide and oxygen. It exchanges these gases with the atmosphere to keep a balance between the ocean and the atmosphere.

What is atmosphere?

An atmosphere is defined as the layers of gases surrounding a planet or other celestial body. Earth's atmosphere is comprises of about 78% nitrogen, 21% oxygen, and 1% other gases.

Dissolved oxygen and carbon dioxide are important for marine life. Marine plants use dissolved carbon dioxide, sunlight and water to make carbohydrates through the process of photosynthesis.

Cold water holds more gas than warm water and seawater with low salinity holds more gas than high salinity water. Deep water, that has a high pressure, holds more gas than shallow water.

why not test for pathogens like salmonella directly rather than use an indicator organism such as a coliform?

Answers

Indicator organisms are organisms that are utilized to detect the presence of another organisms that cannot be easily identified.

We do not test for pathogens like salmonella directly but use an indicator organism like coliform because these pathogens are not easily isolated and they are much harder to identify.

Pathogens like salmonella are not tested for directly because they are much lower in numbers when found in wastes or waterbodies and to identify them directly is expensive.

Also testing directly for these micro-organisms is very expensive and non-viable. So it is better to use indicator organisms to detect their presence.

Answer:

Explanation:

In frost wedging, a crack expands when water freezes. When the water melts/thaws it can seep into new fissures in the rock.

What is frost wedging?

Water that seeps into cracks and freezes expands, resulting in frost wedging also known as ice wedging. The growth causes the fissures to widen. How often something freezes and thaws affects how effective frost wedging is.

During the "frost wedging" process, water seeps into rock fractures, causing the gaps to widen when the water expands upon freezing. The effectiveness of frost wedging is influenced by how frequently it freezes and thaws.

Frost wedging is a type of physical weathering in which rocks are degraded by the cycle of freezing and thawing.

Thus, Banks are filled above.
