In New England, it is common to find striations in the surface of exposed rock outcrops. These linear grooves are primarily produced by:
  1. Ice that is well below its freezing point at the base of surging glaciers.
  2. Extreme temperature changes that produce fractures in the bedrock underlying glaciers.
  3. Large rocks that are embedded in the base of glaciers.
  4. Silt-rich water under tremendous pressure at the base of continental glaciers.

The extensive coal beds that formed during the Pennsylvanian period are primarily made from:
  1. The compressed remains of microscopic marine organisms.
  2. Solidified oil deposits that were slowly heated over millions of years.
  3. The fossilized remains of swamp vegetation.
  4. Lithified mud deposited when shallow seas covered parts of North America.

Measuring the age of a lava flow by radiometric dating requires:
  1. Comparing the proportion of radioactive parent isotope to stable daughter product in the rock.
  2. Assessing the level of radioactivity emitted by the isotopes in a sample of the rock with a Geiger counter.
  3. Evaluating the changes in the rock's mineral structure to determine the sample's exposure to ionizing radiation.
  4. Analyzing changes in the atomic number of the radioactive isotopes in the rock by measuring beta and alpha emissions from a sample.
