Answer:
B. History shows how events over time relate, while geography shows how the land changes over time.
Step-by-step explanation:
The relation between Geography and History is very close. This two disciplines complement each other precisely.
History is the science that has as its object of study the past of humanity, and all the events studied by this discipline are linked to space.
Geography is the science that studies the earth's surface, the societies that inhabit it, landscapes, places and regions.
Without prior and detailed knowledge of Geography, is not possible the study of History.
