What is likely causing the movement of the tectonic plates? What effects of these movements do we see or experience on the surface of Earth?

Tectonic shift is the movement of the plates that make up Earth's crust. ... The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift.

Step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
