Stage 1: High Equilibrium
High birth rate and high death rate
Stage 2: Early Population Increase
Decreasing death rate, constant birth rate
Stage 3: Late Population Increase
Death rate stabilizes at a lower amount, birth rate decreases
Stage 4: Low Equilibrium
Low birth rate and low death rate
Answer: Option (A) and (C)
Explanation: In case of slow sea floor spreading, the magma within the crust doesn't get proper way to exert the force upward because of its slower rate of spreading. Due to this, rifting occurs along the mid oceanic ridge.
Due to continuous rifting, it forms a valley known as the rift valley. This rift valley lacks in ridge and is comparatively smooth compared to a fast spreading sea floor, in which the topography appears to be rough and ridges are formed.
Thus, the statements that are true are option (A) and (C).
