The broad shape and gentle slope of Hawaiian volcanoes are, to a great extent, a result of the erupted magma's:
  1. High gas content.
  2. Mafic composition.
  3. Low iron content.
  4. Felsic composition.
See answer
27.
Which of the following are landscape features typically associated with an active strike-slip fault?
  1. Hanging valleys and tarns.
  2. Kame terraces and eskers.
  3. Horsts and grabens.
  4. Scarps and sag ponds.
See answer
28.
Lichens, plant roots, and fungi are able to chemically weather rock. These organisms typically accomplish this by:
  1. Drawing molecular water from the crystals that make up the rock.
  2. Producing acids that cause the decomposition of the rock.
  3. Extracting minerals directly from the rock through osmosis.
  4. Manufacturing salts that alter the rock's crystal structure
See answer
29.
Which of the following properties of water is primarily responsible for its role in mechanical weathering?
  1. Water increases in density as it goes from 0°C to 4°C and then decreases above 4°C.
  2. The capacity of liquid water to store heat energy is very high.
  3. The hydrogen bonding between water molecules gives it a high surface tension.
  4. Water increases in volume as it goes from a liquid to a solid state.
See answer
30.
In some desert regions, a thin layer of closely packed pebbles and cobbles covers the ground surface. This phenomenon, known as desert pavement, is primarily caused by the:
  1. Differential erosion of sediments by wind.
  2. Slow dispersal of material from the base of alluvial fans by gravity.
  3. Breakup of bedrock under hot and dry conditions.
  4. Deposition of coarse-grained sediments during flash flooding.
