Question

1. the theory of plate tectonics helps to explain the formation of which of the following physical features?

islands
mountain ranges
all of the above
continents

Explanation:

The theory of plate tectonics explains geological features. Islands can form from volcanic activity at plate boundaries. Mountain ranges are created by plate collisions (e.g., Himalayas from Indian - Eurasian plate collision). Continents' positions and shapes are due to plate movements (continental drift is part of plate tectonics). So all these features are explained by plate tectonics.

Answer:

All of the above
