Jessica made two identical models of a river using trays filled with sand. She poured a cup of water into the top of the first tray and then poured a gallon of water into the top of the second tray. What would one expect Jessica to have observed?
The gallon of water would have caused more erosion than the cup of water.
The cup of water would have caused more erosion than the gallon of water.
The cup of water and the gallon of water would not have caused any erosion.
The cup of water and the gallon of water would have caused the same erosion.
The picture shows a mass inside of a building that can sway called a tuned mass damper. Which of the following best explains the purpose of a tuned mass damper?
to add weight to the center of a building, adding to its force of gravity
to prevent a building from moving by anchoring it around the mass
to move in opposition of a swaying building, making it more stable
to reduce the weight of a building and make it more flexible

In many places, sand is being pumped from the sea floor onto the beaches. Why is there a need to put sand on beaches?
The sand on the beaches wears out.
The wave action causes erosion of the sand.
Too much sand is piled into sand dunes.
Old, dirty sand has to be replaced.
Which human intervention should be used in an area prone to flooding?

distance
magnitude
time
epicenter
Do earthquakes occur underwater?
