|---|---|
| Why are the oceans salty? | The rocks on land contain calcium carbonate sulfate and sodium chloride. The process of weathering breaks down the minerals in these rocks and salts, and they dissolve in the water as rivers and streams wash the salts from the land into the ocean. |
| What does the seafloor look like? | The ocean floor is as varied and irregular as the land we can see. It has mountains and plains and valleys and ridges and volcanoes and just about any other land feature you could name. |
| How do temperature, salinity, and density affect ocean structure? | As temperature increases, the space between water molecules increases which therefore decreases. If the temperature of water decreases its density increases, but only to a point. At a temperature of 4° pure water reaches its maximum density, |
| what is the definition of salinity. | Salinity is the saltiness or dissolved salt content of a body of water |
| define seawater | water in or taken from the sea |
| define brackish | slightly salty, as is the mixture of river water and seawater in estuaries. |
| define abyssal plain | An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3000 and 6000 m. |
| true or false is the pacific the deepest and largest ocean | true |
