Help please! 1. Which of the phrases below best describes tectonic force? (Points : 1) The action of glaciers sliding across terrain The pressures created by molten rock far below the earth’s surface The erosion of running water which creates channels and canyons in rock A force within the earth that causes the crust to move

Answer 1

The correct answer is "A force within the earth that causes the crust to move".

Tectonic refers to the earth's crust within the theory of plaque tectonics. The theory establishes that movement from  seven major plates comprising the lithosphere have given shape to mountain ranges and volcanos over 3 billion years of history.

This theory was accepted  in 1960 along with new information on floor spreading

Answer 2

Well, it is asking for a force, and tectonic plate shift causes Earth's crust to move, so the last answer is the most accurate.
