Question

what role do convection currents in the earths mantle play in the movement of tectonic plates, and how do they contribute to plate tectonics?convection currents are unrelated to plate movement; they only affect the temperature of the mantle.convection currents create magnetic fields within the earth; this magnetic force pushes the plates.convection currents in the mantle cause the movement of tectonic plates by transferring heat; warmer material rises, cooler material sinks, and this flow drives the plates.convection currents are responsible for earthquakes, not plate movement.which of the following is not a piece of evidence supporting the theory of plate tectonics?fossil similarities on different continentsthe distribution of earthquakes and volcanoesthe age of the earths corethe fit of continents on a global map

Explanation:

For the first question: Mantle convection currents transfer heat via cyclic movement of warm rising material and cool sinking material, which directly drives tectonic plate motion. The other options are incorrect: currents are related to plate movement, do not use magnetic fields to push plates, and are linked to plate movement (not just earthquakes).
For the second question: Fossil similarities, earthquake/volcano distribution, and continental fit are all key evidence for plate tectonics. The age of Earth's core does not relate to the theory of how tectonic plates move and interact.

Answer:

1. Convection currents in the mantle cause the movement of tectonic plates by transferring heat; warmer material rises, cooler material sinks, and this flow drives the plates.
2. The age of the Earth's core
