What do convection currents cause?
Convection currents are the result of differential heating.
Lighter (less dense), warm material rises while heavier (more dense) cool material sinks.
It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth..
What happens when magma convection currents move in opposite directions?
Answer: During the “magma convection currents”, This is because if the “magma convection currents” flow in opposite direction, the plates present floating on the molten magma also float apart, causing divergent plate boundaries.
How do convection currents affect weather?
During convection, cooler water or air sinks, and warmer water or air rises. This movement causes currents. … These currents move water all around the earth, bringing warm water to cooler areas and vice versa. This redistributes thermal energy and causes changes in the weather.
What causes the tectonic plates to move?
The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth’s mantle and fit snugly against one another. The heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other.
How do plates move by convection currents?
The Earth’s crust is broken up into pieces called plates. The crust moves because of movements deep inside the earth. Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates.
What are the 3 causes of plate movement?
Mantle convection currents, ridge push and slab pull are three of the forces that have been proposed as the main drivers of plate movement (based on What drives the plates? Pete Loader).
Which direction do convection currents move?
Explanation: Convection currents happen in fluids with a heat source. Hot liquid or gas near the heat source becomes hotter and less dense, so moves upwards. This forces the cooler stuff at the top to move back down.
Which layer of the Earth produces convection currents which move tectonic plates?
the mantlePlate movement. Heat from the core causes convection currents in the mantle. These currents slowly move the crust around. In some places the crust is destroyed.
Where do convection currents occur?
Answer and Explanation: Convection currents on Earth occur in the mantle of the Earth. It is causes by the rise of hot magma towards the Earth’s crust, becoming cooler, and…
