yes
This pH is slightly basic.
probally fresh because no salt in mouth or eyes addition: it is easier to float/swim in seawater since seawater is denser than fresh water.
No, it is seawater.
by evaporation
Melting of polar ice caps and glaciers adds fresh water to seawater. Precipitation in the form of rain or snow also contributes fresh water. Rivers and streams flowing into the ocean bring in fresh water. Groundwater seepage into the ocean is another natural source of fresh water.
the seawater smells
Seawater can contain irritants like salt, algae, and microorganisms that can cause skin irritation and dryness, leading to redness and itching. The high salt content in seawater can also strip the skin of its natural oils, further exacerbating these symptoms. Rinsing off with fresh water and applying moisturizer after being in seawater can help alleviate these effects.
Fresh water is considered neutral with a pH around 7. However, the pH of fresh water can vary slightly depending on factors such as the presence of minerals and organic matter.
When a ship sails from seawater to fresh water, the buoyancy of the ship increases because fresh water is less dense than seawater. This can cause the ship to ride higher in the water. Additionally, there may be a slight increase in the ship's speed due to the lower density of the fresh water offering less resistance to the hull.
no.they must have fresh water to live.
When fresh water meets seawater, it is called a "brackish water" environment. This occurs in estuaries or coastal wetlands where rivers flow into the ocean.
Freezing desalination works by freezing seawater and separating the ice crystals from the remaining saltwater. The ice crystals are then melted to produce fresh water, while the saltwater is left behind. This process helps remove salt and impurities from seawater, resulting in fresh water that is safe for consumption.
