Divergent Plate
by Bt Mawar Malyanah
1. Definition
1.1. Plates move away from each other
2. Great African Rift Valley
3. Types of plate divergence
3.1. Oceanic-oceanic
3.1.1. Magma rises to fill the gaps when the plate move apart.
3.1.2. New sea floor is formed when magma cools and solidifies known as sea-floor spreading.
3.1.3. Newly formed rocks are closest to the plate boundaries and therefore younger than those further away
3.2. Continental-continental
3.2.1. When plates diverge or move apart, it is being stretched, causing fractures to form at the plate boundary.
3.2.2. Land between the continental crusts sinks, forming a linear depression known as rift valley.
