What else can I help you with?
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.
Why car exhausts rust so quickly?
If the vehicle has a stainless steel exhaust system it will last the life of the car. If it does not and you drive in roads treated with salt it will not last as long. Surface rust does not mean the exhaust in need of repair. Surface rust is normal on a steel exhaust system.

What part of speech is the word drive?
The word driving is a verb. It is the present participle of the verb drive.
Is the 2013 Smart Fortwo front wheel drive rear wheel drive or four wheel drive?
The 2013 Smart Fortwo has rear wheel drive.
What is the circulation within earths mantle called?
The circulation within Earth's mantle is called mantle convection. This process involves the movement of hot material rising and cool material sinking in the mantle, creating convection currents that drive plate tectonics.
What is earths mantle heated by?
Earth's mantle is mainly heated by the decay of radioactive isotopes and residual heat from the formation of the planet. This heat causes convection currents in the mantle which drive plate tectonics and other geological processes.
What is the two layers below earths surface in which convection takes place?
The two layers below Earth's surface where convection takes place are the mantle and the outer core. In the mantle, convection currents are responsible for plate tectonics and the movement of Earth's lithosphere. In the outer core, convection currents drive the movement of molten iron that generates Earth's magnetic field.
What are parts of the earths mantle?
The Earth's mantle consists mainly of the upper mantle and the lower mantle. The upper mantle is made up of solid rock, while the lower mantle is composed of more solid and dense rock. The mantle plays a crucial role in the movement of tectonic plates and the convection currents that drive plate tectonics.
The mantle comprises what percentage of earths volume?
15
What powers the plate tectonics?
The plate tectonics are powered by the heat generated from the Earth's core. This heat causes the movement of molten rock in the mantle, creating convection currents that drive the movement of tectonic plates over the Earth's surface.
What role does mantle convection play in plate motion?
Convection currents in the mantle create plate tectonics.
What is the ultimate source of heat that moves the plates?
The ultimate source of heat that drives plate tectonics is believed to be the Earth's internal heat from radioactive decay in the mantle. This heat causes convection currents in the mantle, which in turn drive the movement of the tectonic plates.
How do you use earths mantle in a sentence?
The Earth's mantle is a layer of solid rock beneath the Earth's crust, extending to a depth of about 1,800 miles. Scientists study the characteristics of the Earth's mantle to understand the processes that drive plate tectonics and influence volcanic activity on the planet.
What is the internal source of earths energy?
The internal source of Earth's energy is primarily the heat generated by the radioactive decay of elements like uranium, thorium, and potassium in the planet's core and mantle. This heat causes convection currents that drive plate tectonics, volcanic activity, and geological processes on Earth's surface.
Does the sun support the process of plate tectonics?
No, the sun's energy heats the Earth's atmosphere and surface, but it does not directly drive plate tectonics. Plate tectonics is primarily driven by heat from the Earth's interior, specifically by the heat generated by radioactive decay in the mantle.
When will plate tectonics stop?
When the earth cools because it does not have enough radioisotopes left in the mantle and core to keep them hot enough to drive mantle convection.
