Answer:
No heat no endogenous tectonic processes.
Explanation:
There is a great influence of the earth's internal heat on endogenous tectonic processes  because the internal heat causes the plates to melt due to which earthquakes occur. Without this internal heat of earth, no endogenous tectonic processes occur because these processes require heat to happen so we can say that internal heat of the earth has a great impact on the happening of endogenous tectonic processes.
