Question

match each statement to “law” or “theory.” “species share common ancestors and change over time.” “in a closed system, mass stays the same during reactions.” “earth’s plates move and interact at boundaries.” which row is correct?
1 = theory; 2 = theory;
1 = theory; 2 = law; 3 = theory
1 = law; 2 = theory; 3 = law
1 = law; 2 = law; 3 = law

Explanation:

1. "Species share common ancestors and change over time" is the theory of evolution, a well-supported scientific theory that explains observed patterns of life.
2. "In a closed system, mass stays the same during reactions" is the Law of Conservation of Mass, a measurable, consistent natural law describing a predictable phenomenon.
3. "Earth's plates move and interact at boundaries" is the theory of plate tectonics, a comprehensive explanation for geological features and events.

Answer:

1 = Theory; 2 = Law; 3 = Theory
