How are convection currents in the mantle and in the oceans similar How are they different?
The ocean currents are colder than the currents in the mantle,and the are located in different areas.
What causes convection currents in the earth's mantle and oceans and in the air?
Heat differentials.
Do convection currents in the oceans cause tectonic plates to move?
No, convection currents in the upper mantle cause tectonic plates to move.
Do convection current in oceans cause tectonic plates to move?
No, convection currents in the upper mantle cause tectonic plates to move.
What is true about convection in Earth's mantle and tectonic plate motion?
Within the earth's mantle, which is semi-molten, there are convection currents caused by differences in temperature. These currents apply force from beneath to the plates of the earth's crust. The plates move slightly, which causes the very slow change in the shapes of our continents and oceans (and also causes occasional earthquakes).All of this is true about convection currents, however there is significant dispute as to whether the tectonic plates are actually moved by convection currents. It could equally be true that "There are no convection currents in the Earth's mantle". Although is is the best theory going, there has been insufficient evidence that these currents actually exist. Alternative theories include:Continental drag: As a plate is subducted beneath another, the weight of the sinking end pulls the rest of the plate with it. This causes continental drift. The biggest flaw is that not all plates even have destructive boundaries.Hotspots: Hotspots themselves are responsible for continental drift (a similar sort of idea to convection currents, but we do know that hotspots exist). The biggest flaw is that not all plates have a hotspot on them.
Does convection currents in the oceans cause tectonic plates to move?
false
How do convection currents distribute heat in the oceans?
the radiation from the sun will send heat to the ocean and the heat would make currents hot Basically a convection current
What causes convection currents to form in oceans?
Lighter, warm material rises while more heavier, cool material sinks. It is the movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth. In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath.
What is the major source of energy that powers the convection currents in the atmospheres and oceans?
Vertical convection in both the ocean and atmosphere is caused by uneven HEATing.The source of energy for convection in the ocean and atmosphere is heating from the sun.
What are some ways that ocean currents and wind are similar?
They are similar because if you think about it carefully, the ocean currents are caused by the air currents and the air currents are caused by the ocean currents, so, it is all a scientific cycle.
What type of current is caused by wind on the oceans surface?
Surface ocean currents are caused by winds. As wind blows across the surface, the wind pulls the water and causes waves.
What makes convection currents more dense?
Basically, Density is the result of an amount of mass packed into a given space. The more mass packed into a space, the denser the object and the less mass, the less dense it is. Convection is heat transfer by fluid or liquid movement. It is found in the air (as wind) in the oceans (as currents) and in the mantle of the Earth (it affects plate movement). Warm air or water or mantle rises and is replaced by the cooler mass. In the case of the air and water, the cooler, denser air and water falls due to having more mass and gravity pulling on it. In the mantle, the cooler mantle is falling and its density allows the core's gravity to pull on it. But the deeper into the mantle, temperature increases instead of decreasing due to pressure in the outer and inner core. Density and convection work together to help keep the balance of systems in all areas of Earth's processes.
