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

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.

  1. High gas content.
  2. Mafic composition.
  3. Low iron content.
  4. Felsic composition.

Studies during the 1950s and 1960s showed that the ferromagnetic minerals in ocean-floor basalts aligned with Earth's magnetic field when the basalts were still molten. This information provided evidence supporting:
  1. The theorized stability of Earth's rotational velocity
  2. A four-billion-year-old estimate of Earth's age.
  3. The hypothesized liquid state of the upper mantle.
  4. A mechanism to help explain how lithospheric plates moved apart.

Seismologists first established the physical character of Earth's outer core based on the fact that:
  1. S waves do not pass through liquid substances.
  2. P and S waves are reflected from solids at different angles.
  3. P waves do not pass through high-temperature materials.
  4. P and S waves are refracted differently from irregular surfaces.
