B Correct answer
Explanation


  • So, even though it is hotter in the inner core, the pressure in the core is also higher, and you can have solid iron-nickel instead of liquid.
  • It is made of iron and nickel. 
  • This is above the Earth's solid inner core and below the mantle. Its outer boundary is 2,890 km (1,800 mi) beneath the Earth's surface..
  • Convection of liquid metals in the outer core creates the Earth's magnetic field.

  1. Laurensia

  2. Gondwana Land

  3. Both A & B

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • 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.
