It is also important to check that your urban growth and development projections do not conflict with neighboring jurisdictions and local governments in the area. â¢ Be sure to update your land use regulations to accommodate the new infill development that will result from implementation of the urban growth boundary.
This formation of new land results from the ocean floor rising. What Happens When New Islands Form. Subduction earth movements is the cause of new underwater islands and results in a displacement of ocean water. It happens when an ocean plate slides beneath a continental plate.
But why is the ocean salty? Ocean water contains lots of different mineral salts: sodium, chloride, sulfate, magnesium, calcium, potassium, bicarbonate and bromide. These salts enter the ocean through rivers, which pass over rocks and soil, picking up salt along the way. This salt builds up in the ocean because the only way water can leave the ocean is through evaporation. And when the water evaporates it doesn't take the salt with it. So you end up with less water, and the same amount of salt, resulting in a pretty salty sea.
