|
|
|
Ocean currents because the less dense material rises to the surface.
|
|
|
Ocean ridges because they are diverging place boundries.
|
|
|
Plate boundries because there is techtonic movement along all the plate boundries.
|
|
|
Convection currents as a result of differences in density.
|
|
|
Groundwater because it is always moving beneath the surface.

Detailed explanation-1: -Convection currents drive the movement of Earth’s rigid tectonic plates in the planet’s fluid molten mantle. In places where convection currents rise up towards the crust’s surface, tectonic plates move away from each other in a process known as seafloor spreading (Fig. 7.21).
Detailed explanation-2: -The forces that drive Plate Tectonics include: Convection in the Mantle (heat driven) Ridge push (gravitational force at the spreading ridges)
Detailed explanation-3: -Heat from deep within Earth is thought to keep the asthenosphere malleable, lubricating the undersides of Earth’s tectonic plates and allowing them to move. Convection currents generated within the asthenosphere push magma upward through volcanic vents and spreading centres to create new crust.
Detailed explanation-4: -Answer and Explanation: Convection occurs in the asthenosphere due to heat generated in Earth’s core. This heat drives convection currents throughout the mantle because magma is able to move as a viscous fluid, rising and turning over again as it is heated from below.
