Final answer:
Scientific laws are concise descriptions of patterns in nature, while theories are complex explanations of how nature works.
Step-by-step explanation:
A scientific law is a description of a pattern in nature that is true in all circumstances. Laws are often concise and can be expressed as single sentences or equations. For example, Newton's second law of motion relates the motion of an object to the force applied, the mass of the object, and the object's acceleration through the equation F = ma.
On the other hand, scientific theories are overarching explanations of how nature works and why it exhibits certain characteristics. They are less concise and explain a group of related phenomena. For example, the Theory of Evolution and the Theory of Relativity are complex theories that cannot be expressed concisely enough to be considered laws.
