Question

Since plate tectonic processes are powered by heat energy coming from radioactive decay
will plate motion cease? If it does, what will happen?​

Answer 1

Answer:

HEY HERE IS YOUR ANSWER....

Explanation:

There’s no geological artist quite like Earth’s plate tectonics. Thanks to this ongoing operation, we have mountains and oceans, terrifying earthquakes, incandescent volcanic eruptions, and new land being born every single second.

Answer 2

Yes, tectonic plates motion may cease when the radioactive decay becomes stable.

Explanation:

• Radioactive decay is not infinite. More than half of the U238 that was initially present has decayed. The decayed uranium has formed a stable compund called lead 206.
• In future when the heat from the core becomes insufficient to drive the tectonic plates, the tidal forces produced by the moon and the sun will become less, since the moon would drive far away from the earth.
• Since the plates has stopped moving no more mountains are formed, volcanic eruptions stop and the existing moutains would fade away. Meanwhile the expanding sun would melt the earth crust.
