1. As the plates move apart, nearby sea and ocean water will flood and erode the land.
2. As the plates move apart, sea levels will rise in the Red Sea, eroding coastlines.
3. As the plates move apart, seawater will erode the land underneath the rift zone, creating caves.
4. As the plates move apart, volcanic activity will shape the land along the rift as magma rises through plate fissures.
Here are the correct answers:
1. As the plates move apart, nearby sea and ocean water will flood and erode the land. The diverging plates create low-lying areas in the rift valley that seawater can fill, leading to both flooding and erosion.
2. As the plates move apart, sea levels will rise in the Red Sea, eroding coastlines. The tilting of the African Plate due to the rift's expansion causes Red Sea water levels to rise, potentially causing coastal erosion and flooding.
3. As the plates move apart, seawater will erode the land underneath the rift zone, creating caves. As the land stretches and thins due to the diverging plates, weak spots susceptible to seawater erosion form, potentially leading to cave development.
4. As the plates move apart, volcanic activity will shape the land along the rift as magma rises through plate fissures. The East African Rift Zone is a hotspot for volcanic activity, and the diverging plates provide pathways for magma to rise, shaping the land through eruptions and lava flows.
Therefore, the correct answers are 1, 2, 3, and 4.
