Describe the movement of Earth’s mantle. Explain how convection currents can cause tectonic plates to move.

Answer:

Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart. Where convection currents converge, plates move towards each other.

Convection currents from core radioactive decay rise and fall in the mantle. Convection currents move plates. Plates separate near convection currents. Plates converge at convection currents.

Convection currents are caused by differential heating. Warm, less dense, lighter material rises while cool, more dense, heavier material sinks. Convection currents are patterns of circulation that are produced by this movement in the Earth's mantle, oceans, and atmosphere.

Convection currents are produced by radioactive decay in the core and are caused by heat rising and falling inside the mantle. The plates are moved by convection currents. Plates separate where convection currents split close to the Earth's crust. Plates move in the direction of one another where convection currents converge.

first answer (melted rock in the interior of the earth cools after so many years, turns to solid rock. after plates into each other, mountains form due to pressure which brings the rock on the earth's surface. another way is when rocks flow out with lava, the lava cools and hardens into a rock). this is my first answer. Answer about how you think melted rock deep within Earth could change over time. Would you revise your answer now? If so, how? If not, explain why.
