How did new evidence found by the marie Tharp and Bruce heezen add onto continental drift and create the theory of plate tectonics? A.

they proposed that mountain ranges at the edge of continents helped explain how continents used to fit together?

A. Yes, they proposed that mountain ranges at the edge of continents helped explain how continents used to fit together. This observation supported the concept of continental drift, as it suggested that the continents were once joined together and had moved apart over time. This evidence contributed to the development of the theory of plate tectonics, which explains that the Earth's lithosphere is divided into several large, rigid plates that move and interact with each other.

Which word best describes the statement that mass is neither made nor destroyed by chemical reactions or physical changes?

The word that best describes the statement is "conservation."

Which word best describes the stately That mass is neither made nor destroyed by chemical reactions or physical changes? A law B experiment C theory D hypothesis

The word that best describes the statement is "law."

Which Ort of Newton’s second law of motion explains why it is easier to push an empty cart than a full one? A an object with greater mass requires less force to move. B a greater force is needed to move an object with a greater mass. C a greater force will cause a greater increase in acceleration.

The correct choice is B - a greater force is needed to move an object with a greater mass. This is explained by Newton's second law of motion, which states that the force required to accelerate an object is directly proportional to its mass. Therefore, a heavier object requires more force to accelerate or move compared to a lighter object.
