Here's why:
* Chemical erosion involves the breakdown of rocks and minerals through chemical reactions. Water is a powerful solvent and can dissolve many minerals, including salt.
* Physical erosion involves the movement of rocks and sediment by forces like wind, water, or ice. While physical erosion can transport dissolved salt, it's the chemical process of dissolving the salt that is the primary factor in its movement.
Examples of chemical erosion moving dissolved salt:
* Ocean currents: Salt dissolves in seawater and is transported by ocean currents.
* Groundwater flow: Rainwater seeps into the ground, dissolving salts and minerals. This salty water flows underground, carrying the dissolved salt.
* Weathering: Rainwater can react with rocks and minerals, dissolving salt and other minerals, which can then be carried away by wind or water.
