An open circuit is one where the continuity has been broken by an interruption in the path for current to flow. A closed circuit is one that is complete, with good continuity throughout.
Explanation:
For instance, a simple light switch opens and closes the circuit that connects a light to a power source. When you build a circuit, it's a good idea to disconnect the battery or other power source when the circuit is not in use.
The Mississippi delta is located on the northwest part of the state of Mississippi and is the most southern place on earth and is 7,000 square miles of alluvial flood plains are created by the regular flooding of the Mississippi and Yazoo rivers for thousands of years.
The river deposited sand, and clay, silt along its banks and in adjacent basins, and is shaped of a bird's foot reflecting the dominance of the river over the hydrological and processes. As the river changes its course the natural flow of freshwater and sediments change as well.
