Correct Answer:
(B)
Tectonic activities
Continents rest on massive slabs of rocks called tectonic plates. These plates are always moving and interacting in a process called Plate tectonic activity. Through these tectonic activities, continents shift position on Earth’s surface. By about 175 million years ago the Pangea (the Supercontinent) landmass began breaking up due to continental drift, theory. Slowly it separated in pieces and assumed their position as the continent we recognize today.

In Carboniferous period, the whole land mass on the Earth was unified and was named as Pangea. This Pangea Supercontinent was surrounded by a super-ocean which was named ‘Panthalassa’ by Wegener.

Folding is the result of-
Correct Answer:
(C)
Orogenic force
The Earth’s surface experiences different types of forces. The orogenic force takes millions of years to build a mountain from plain and sea bed. These forces due to the interaction between tectonic plates, crumpled and pushed upward to form mountain range. Thus, folding is the result of orogenic force.
