A measure that does not change when an object’s location changes. MASS
Speed of an object in a particular direction. VELOCITY
Newton’s ________ Law of Motion: All forces act in pairs. THIRD
The hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations. CONTINENTAL DRIFT
Items that provide evidence that that the continents were once closer together. FOSSILS
The application of engineering to living things, such as humans and plants. BIOENGNEERING
