Base your answers to questions 75 through 79 on the map and table below and on your knowledge of Earth
science. The map shows the area where the Battenkill River flows into the Hudson River north of Albany,
New York. Point A indicates a location within the Battenkill River. The table shows the densities of four
common minerals found in Hudson River sediments.

Samples of minerals listed in the mineral density table with the same shape and size were removed from
the Hudson River and placed in a jar of water. After the jar was shaken, the sediments were allowed to
settle. In your answer booklet, write the mineral name from the table next to the layer in the diagram where each mineral is most likely found.
