Which of the following features is not related to volcanic activity?

The correct​ answer is Fold.

Important Points

• A volcano is a vent (opening) in the earth’s crust through which molten material erupts suddenly from a magma chamber below the surface.
• Due to very high temperatures, some rocks slowly melt and turn into a thick flowing matter known as magma.
• Since it is lighter than the solid rock around it, the magma rises and gets collected in magma chambers which eventually pushes through fissures and vents on the earth’s surface.
• These are some features result of volcanic activity:
  • Conical Vent and Fissure Vent.
  • Mid-Ocean Ridges.
  • Composite Type Volcanic Landforms.
  • Shield Type Volcanic Landforms.
  • Fissure Type Flood Basalt Landforms (Lava Plateaus)
  • Crater.
  • Caldera.
  • Cinder cone
  • Geysers
  • dyke
  • Batholith.

Key Points

• Folding occurs under compression when forces act towards each other, such as when plates collide.
• A fold is a bend in the rock strata. 
• Folding: This is a type of earth movement resulting from the horizontal compression of rock layers by internal forces of the earth along plate boundaries.
• A unfold are termed as anticlines. The downfolds are termed synclines Folding.
