Final answer:
The theory of plate tectonics is supported by multiple lines of evidence from various fields of study.
Step-by-step explanation:
The theory of plate tectonics is supported by multiple lines of evidence from various fields of study. One major piece of evidence is the matching shapes of the coastlines of different continents, such as the east coast of South America fitting into the west coast of Africa. This suggests that the continents were once connected and have since moved apart. Other evidence includes the distribution of similar fossils and rock formations across different continents, as well as the occurrence of earthquakes and volcanic activity along plate boundaries.
