What creates recirculating currents and turbulent waters that can swamp vessels and drown boaters?
A low-head dam.
Why are low head dams dangerous to boats?
Low Head dams often have tops that are below the water surface. But aside from their lack of visibility, they can create a fatal trap for small boats. Water going over a low-head dam creates a strong recirculating current (a backroller) and a turbulent upflow (a boil). These currents can push boats back against the downstream side of the dam, where the boats may capsize and their occupants may be pulled under.
What creates the currents in the mantle of the earth?
they are convection currents, caused by the heating effect of the earths core
Describe the effect of temperature on density currents?
when a substance is cooler at the surface, the density increases in the substance.
What creates surface current?
Surface currents are created by air currents, earth's rotation, and positions of the continents.
What creates a continental rise?
Turbidity currents create continental rises.
What iz quatic?
Quatic is when the ocean's currents get gigantic and creates a tsunami.
When the air in the atmosphere is unevenly warm by the suns wind currents are the results?
Essentially, yes: the Sun's heat creates convection-currents.
When the air in the atmosphere unevenly warm by the suns wind currents are the result?
Essentially, yes: the Sun's heat creates convection-currents.
The energy that creates surface ocean currents comes from prevailing winds?
True
What do geologists think creates earths magnetic field?
Electric currents in Earth's molten outer core.
What is an explanation of the process of convection current movement?
Heat rises...cold decends. As each moves it creates currents.
