Final answer:
Plate tectonics can alter global climate through changes in ocean current movements.
Step-by-step explanation:
True: Plate tectonics do affect ocean current movements, which in turn can alter the global climate. Around 40 million years ago, South America and Antarctica were connected, forming a landmass known as Gondwana. As the landmass broke apart due to plate tectonics, it opened up the Drake Passage, a narrow seaway between South America and Antarctica. This allowed the flow of cold Antarctic circumpolar current around Antarctica, which had a significant impact on ocean currents and global climate.
