Solution

The correct option is C Both A & B
  • Many earth scientists use the term "supercontinent" to mean "a clustering of nearly all continents".
  • This definition leaves room for interpretation when labeling a continental body.
  • The landmass of Pangaea is the collective name describing all of these continental masses when they were most recently in proximity to one another.
  • This would classify Pangaea as a supercontinent. According to modern definitions, a supercontinent does not exist today. Supercontinents have assembled and dispersed multiple times in the geologic past (see table).
  • Laurasia was the more northern of two supercontinents (the other being Gondwana) that formed part of the Pangaea supercontinent around 335 to 175 million years ago (Mya).
  • It separated from Gondwana 215 to 175 Mya (beginning in the late Triassic period) during the breakup of Pangaea, drifting farther north after the split.
  • Gondwana also Gondwanaland, is the name given to an ancient supercontinent.
  • It is believed to have sutured about 600 to 530 million years ago, joining East Gondwana to WestGondwana.
  • Gondwana formed prior to Pangaea, and later became part of it.
