Which of the following best represents the sequence by which a continent splits apart?
A) seafloor spreading, then continental rifting, then uplift due to mantle upwelling
B) continental rifting, then seafloor spreading, then uplift due to mantle upwelling
C) uplift due to mantle upwelling, then continental rifting, then seafloor spreading
D) none of these
Continental Rifting
The process by which a continent stretches and splits along a rift, often leading to the formation of new ocean basins.
Seafloor Spreading
A geological process in which new oceanic crust is formed at mid-ocean ridges and spreads outward, contributing to continental drift.
Mantle Upwelling
The ascent of hotter material from the Earth's mantle to the crust, a process that can lead to volcanic activity and continental rift zones.
- Describe the processes responsible for the creation of mid-ocean ridges and the division of continental masses.
- Investigate the range of geological phenomena occurring at divergent plate boundaries.
