Theories and laws both explain how phenomena occur.
Theories and laws both explain how phenomena occur.
The correct response is:
Theories explain why phenomena occur, while laws describe how phenomena occur.
This distinction highlights that scientific theories provide underlying explanations and insights into the mechanisms behind observed phenomena, whereas scientific laws summarize consistent observations and relationships in nature without necessarily explaining the reasons behind them.

Theories explain why phenomena occur, while laws describe how phenomena occur. Theories describe how phenomena occur, while laws explain why phenomena occur. Theories describe how phenomena occur, while laws explain why phenomena occur. Theories and laws both explain why phenomena occur. Theories and laws both explain why phenomena occur. Theories and laws both explain how phenomena occur. Theories and laws both explain how phenomena occur.
The correct response is:
Theories explain why phenomena occur, while laws describe how phenomena occur.
This highlights the fundamental difference between theories, which provide explanations and reasons for phenomena, and laws, which articulate the predictable outcomes or patterns observed in nature.
Which statement is true about the relationship between scientific theories and laws?(1 point)
A true statement about the relationship between scientific theories and laws is:
Scientific laws are descriptions of observed phenomena, while theories provide explanations for those phenomena.
This indicates that laws describe patterns or relationships in nature, while theories aim to explain why those patterns exist.
