The distribution of placer gold deposits in Ghana and Brazil suggests what about their past geographic configuration?
Both were volcanic islands
They shared a connected mountain range
They were once connected as part of a larger landmass
The gold originated in Ghana and was transported by water
The Gondwana tillite is significant evidence of:
Mountain formation
Ancient widespread glaciation
Deep-sea sedimentation
Volcanic activity in Pangaea
Assertion: Gondwana sediments are only found in India. Reason: Lemurs were found in geographically separated regions like India, Africa, and Madagascar.

Seafloor expansion theory
Subduction zone theory
Plate tectonics
Which one of the following is not a minor tectonic plate of the Earth?
Nazca Plate
Cocos Plate
Antarctic Plate
Juan-de-fuca Plate
Assertion(A): The Mid-Atlantic Ridge is an example of seafloor spreading. Reason(R): It is where new crust is formed, pushing continents apart.
