In sea-floor spreading, molten material rises from the mantle and erupts

• along the edges of all the continents.

• along mid-ocean ridges.

• in deep-ocean trenches.

• at the north and south poles.

How is it possible for new crust to be formed without increasing the surface area of the Earth?

Peer scientists reviewing Wegener’s hypothesis of continental drift rejected his notion because

• His evidence was too few to make a valid conclusion 
• He did not explain how continents move and what moves them
• His evidence was not clear in showing  how continents were joined
• He lied by including false evidence

What type of features are associated with a divergent boundary?

• Rift valleys
• Volcanic mountains
• Fold mountains
• Fault block mountains

The mechanism that moves continents is based on heat energy moving by

• Radiation in the core
• Conduction in the lithosphere
• Convection in the Asthenosphere
• None of these options is true
