A batholith is distinguished from a stock by its

  • A.glassy texture
  • B.much greater exposed area
  • C.much smaller exposed area
  • D.concordant relation to the bedding

Answer: B

Correct answer: much greater exposed area

Batholith and stock are both discordant plutonic bodies of the same kind, distinguished only by size: a batholith exposes more than about 100 square kilometres and a stock less. Both cut across the surrounding structure rather than following it, so neither is concordant, and both are coarse-grained rather than glassy.
