Earth's average temperature has been generally increasing for over a century, and moreso in recent decades (about 0.2C/decade in the last few).
what do scientist believe is happening to the segments of the earths crust
it has been washed into the oceans as the continental crust has eroded.
The pacific oceanic plate is sinking beneath conential plate
The plates on either side are moving away from each other.
No, the cycle is driven by the Earths Tilt and Orbit. However the cycle will be modified in its effects by climate changes happening on the Earth.
what do scientist believe is happening to the segments of the earths crust
You can't prevent this from happening because earths weather does what it wants to and you can't control the weather so you can't
Continental drift occurs under the earths crust by convection currents in the mantle which drives the plates. It has been happening since the development of the earths core and is happening now and until the end of the earth.
The plates are pushing against eachother.
a rift is a long deep valleys formed by movement of earths curst
The pacific oceanic plate is sinking beneath conential plate
it has been washed into the oceans as the continental crust has eroded.

The Earths Equatorial diameter is 12756 km, and there are (on average) 149,597,890 km to the sun, so we are talking about 11728 Earths.
