Final answer:
Great Britain was able to resist the German invasion during World War II primarily due to the natural barrier offered by the English Channel, combined with their naval strength and the crucial victory in the Battle of Britain that prevented German air superiority.
Step-by-step explanation:
The geographic features that helped Great Britain resist invasion by the German and Axis powers during World War II were the sea and ocean. The English Channel, a body of water separating Great Britain from continental Europe, served as a natural defensive barrier against the German invasion plan, known as Operation Sea Lion. The Royal Air Force's successful defence in the Battle of Britain prevented German air superiority over the channel, thus thwarting an amphibious invasion. Furthermore, Great Britain's strong naval power created a blockade and used submarines to defend against potential attacks, contributing to their ability to resist invasion by utilizing their geographical advantage.
