Stanley Cupp is learning about two parts of the rock cycle: weathering and erosion. He needs to explain how weathering and erosion are different. How would you explain the difference?
weathering is the breaking down of rocks; erosion is the movement of weathered materials

While watching a baseball game on television you hear the announcer mention that the very cold temperature affects the distance that the ball can be hit. If you were to test this scientific claim what would the dependent and independent variables be?
dependent- distance that the ball is hit independent- temperature of the ball

What can scientists use to prove that organisms have been changing over time?
fossil evidence

What is the principle of superposition?
500
Occurs when cooler, denser mass of a gas or liquid replaces a warmer, less dense mass of a gas or liquid by pushing it upward.
What is convection?

Blake covered a flashlight with a sheet of black paper, then he turned the flashlight on. What color will Blake see on the other side of the paper with the flashlight turned on?
No color will be present because all of the light has been absorbed by the black paper.
