Zone of Leaching - (correct answer)-closer to the ground surface
-water extracts & absorbs ions and picks up clay +carries material further downward.
-water dissolves the surface of grains.
zone of accumulation - (correct answer)-deeper down
-new mineral crystals precipitate out of percolating water/dissolved ions precipitate
-water leaves behind a load of fine clay.
Half Dome is a distinctive peak that developed in the granite bedrock of Yosemite
National Park. The shape of Half Dome is largely a consequence of which of the
following? - (correct answer)exfoliation jointing
The square-shaped void in this rock developed because of the chemical weathering of a
halite (rock salt) crystal. Which of the following types of chemical weathering is most
likely responsible for the removal of the halite crystal? - (correct answer)=dissolution.
-The halite crystal was removed via dissolution in water—the same process that allows
table salt to be dissolved in a glass of water.
The honeycomb-like network of ridges and depressions in these sandstone blocks is
characteristic of physical weathering caused by exposure to seawater. Which of the
following best explains how seawater causes this type of physical degradation? -
(correct answer)=Salt crystals grow in pore spaces, which causes the sand grains to
break apart.
-As the seawater evaporates, salt crystals grow and wedge the grains apart.
This image shows an ancient soil (paleosol) in the Moydart Formation of Nova Scotia,
Canada. The white horizons and nodules are accumulations of the mineral calcite.
Which of the following terms best describes this type of soil? - (correct answer)=aridisol.
