Question

what is tectonic threshold?​

Answer 1

Explanation:

Tectonics, scientific study of the deformation of the rocks that make up the Earth’s crust and the forces that produce such deformation.

This is a special type of intrinsic threshold, the geomorphic threshold (Schumm, 1973). It is a result of landform (slope) change through time to a condition of incipient instability and then failure.

Answer 2

Uplift is the process by which the earth's surface slowly rises either due to increasing upward force applied from below or decreasing downward force (weight) from above. During uplift, land, as well as the sea floor, rises. The outer shell of the earth, the crust, divides into moving sections called plates.
