Heat comes from the core of the Earth. The heat rises to the mantle. Certain parts heat more than others due to different compositions/pressures, so there is movement within the mantle to even it out. Overall, the movement of the thermal energy rises still, so that creates the convection current within the mantle.
This creates locations where the heat from the mantle is more direct on the crust. These locations are called hotspots. The most common example of a hotspot is in Hawaii. It remains in the same place even as the continental and oceanic plates move over it. These hotspots are locations where hot rock (such as basalt) rises and penetrates the surface of the ocean floor or on land. The rock then spreads out and cools. This process and continues, with new rock coming up and the older layers being pushed aside, creating a striped pattern.

How does convection currenctions work inside the earth?
Convection currents happen in the mantle and cause tectonic plates to drift. The earth is made up of the iron and nickel core, then the mantle then the crust. And the earths surface is made up of tectonic plates. These plates move due to convection currents.
Would plate tectonics work if the mantle were made out of normal solid rock?
No, plate tectonics would not work with a solid rock mantle. The movement of tectonic plates is driven by the flow of semi-fluid rock in the mantle. If the mantle were solid, there would be insufficient convection currents to drive plate movement.
How does convection current works?
Convection currents are created by the differences in temperature and density of a fluid. As a fluid is heated, it becomes less dense and rises, while cooler, denser fluid sinks. This continual movement creates a circular flow pattern known as a convection current. It plays a crucial role in processes like weather patterns, ocean currents, and the movement of magma in Earth's mantle.
What are the forces that drives the tectonic plates of the earth?
There are many possible forces or mechanism associated by continental movement.include;sea-floor spreadingthermal plume phenomenaslab-push at mid oceanic ridge.slab-pull at subduction zoneNote that all this mechanism work together
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.

How does convection energy work in natural phenomena such as ocean currents, atmospheric circulation, and the movement of magma in the Earth's mantle?
Convection energy in natural phenomena like ocean currents, atmospheric circulation, and magma movement in the Earth's mantle is driven by the transfer of heat through the movement of fluids. As a fluid is heated, it becomes less dense and rises, creating a convection current. This rising motion displaces cooler, denser fluid, which then sinks and completes the convection cycle. In the ocean, this process helps drive the movement of water in currents. In the atmosphere, it influences weather patterns and wind circulation. In the Earth's mantle, convection currents play a key role in the movement of tectonic plates and the generation of volcanic activity.
How do convection currents work in the mantle?
What forces would lead to the movement of the plates over the surface of the earth? At this time it is believed this movement results from mantle convection. Deep within the earth there is a large amount of heat coming from two sources: the magma remnants of the Great Bombardment, and radiation from radioactive elements. This heat, in accordance with the 2 ndlaw of thermodynamics, must flow to a cooler place, and subsequently rises to the surface of the Earth. If the Earth were smaller, this heat would flow by conduction, but because of the relatively large size of the Earth, convection also takes place. Thus, as in heating a pot of water on a stove, convection currents are established within the earth, which bring warm material to the surface and send cooler material to the interior.

Define convection currents?
a heat energy traveling upward from the hot lower mantle to the cooler upper mantle
How does convection currents work in the atmosphere?
Convection currents in the atmosphere occur when warm air rises and cool air sinks. The heating of the Earth's surface by the sun creates temperature differences that drive these currents. As warm air rises, it cools and sinks back down, creating a continuous cycle that helps distribute heat and moisture around the globe.
How do convection currents affect the rock cycle?
Well, isn't that just a happy little question! Convection currents deep within the Earth help move molten rock, creating magma chambers and causing volcanic eruptions. This volcanic activity plays a big role in the rock cycle by forming new igneous rocks. Just like how we add layers of paint to create a beautiful painting, these processes work together to shape and transform the Earth's surface over time.
What energy source drives convection?
Convection currents are driven by an uneven temperature. It is the rise and fall movement of matter from a hot region to a cool region.
