Question

q5. (s c.6.n.2.2)
the theory of plate tectonics explains the movement of earth’s crust. which feature best demonstrates why it is considered a theory?
it is only an educated guess with little evidence.
it cannot change in the future.
it is based on multiple types of evidence, including fossils, earthquakes, and seafloor spreading.
it is a proven law.

Explanation:

A scientific theory is well - supported by evidence. Plate tectonics has evidence from fossils (showing past land connections), earthquakes (indicating plate boundaries), and seafloor spreading (new crust formation). It's not just a guess, can change with new evidence, and is not a law.

Answer:

It is based on multiple types of evidence, including fossils, earthquakes, and seafloor spreading.
