Why do convection currents move in circular motion?
Convection Currents are circular patterns of heat and cooling that move liquids and air. Hot air rises due to its lower density and then sinks when it cools.
What happens when magma convection currents move in opposite directions?
Answer to: The plate tectonics become separated during the “magma conection currents”. This happens because plates floating on the molten Magma in opposing directions of the “magma conection currents” can also separate, creating divergent plate boundaries.
How do convection currents move magma?
The idea is that heat from the earth’s inner causes convection currents within the magma. Some magma rises toward the surface because of heat. The magma moves away from the hot spot when it reaches the surface.
What would happen if there were no convection current?
If there were no convective currents on Earth, it would be a sign that the inner Earth is solidified. We would therefore not have plate tectonics. Plate Tectonics is the theory that our Earth’s crust is composed of plates of varying sizes, which move slowly around the planet.
Why does convection occur in the mantle?
Mantle Convection is caused by relatively hot rocks being less dense and rising in a gravitational fields, while relatively cold rocks tend to sink and be more dense. The heat flux is an upward heat flux. This counterflow occurs when hot rocks rise and cold rocks fall.
Which two options are a result of convection currents in the air on Earth?
The correct answers are B. Clouds or D. Storm systems. Convection currents result from a physical-chemical process where chemicals are heated, decreasing their density and causing them to rise.
What is the correct order of Earth’s layers?
They are in the order of the exterior to the inside – the crust and mantle, as well as the outer core and inner core.
What is the difference between convection and convection current?
Convection, in short, is the transfer heat through moving mass. Convection currents refer to fluids that are moving due to a temperature difference or density within the material. Convection currents can only be seen in liquids and gases because particles in solids are locked in place.
