Example of theory modification

Back

The theory of plate tectonics was refined over decades with more evidence from geology and oceanography.

Front

Interconnectedness of theories

Back

Theories often explain a wide range of phenomena, allowing for modifications without abandoning core principles.

Front

Role of peer review

Back

Peer review encourages continuous refinement of theories, making them more robust and reliable.
