Question

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.

Identify the diameter of the largest particle that would be carried at point A when the velocity of
the Battenkill River is 50 cm/s. [1]

Answer 1

The table shows that amphibole has a density 3.3 g/cm^3; feldspar has 2.6 g/cm^3, garnet has 4.2 g/cm^3, and finally quartz has 2.7. This means that garnet has the greatest density.

The diameter of the largest particle that would be carried at point A when the velocity of the Battenkill River is 50 cm/s is 0.8 to 1.1 cm.

So, The answer ranges from any value of 0.8 cm to 1.1 cm.
