GEOLOGY

Detailed explanation-1: -A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust.

Detailed explanation-2: -When two plates move away from each other they create a divergent boundary. When this happens under oceans, new ocean floor is created. When two plates move past each other, they create a transform fault. The movement is jerky, and can cause earthquakes.

Detailed explanation-3: -Normal faulting occurs when two plates move away from each other, causing one to slide down relative to the other.

Detailed explanation-4: -Explanation: When two plate move towards each other they converge or come together. The collision between two plates that are moving towards each other is called a convergent boundary. When an ocean plate meets a continental plate at close to a straight line ( 180 degrees) the result is a subduction zone.

Detailed explanation-5: -Hot magma rises from the mantle at mid-ocean ridges, pushing the plates apart. Earthquakes occur along the fractures that appear as the plates move apart. Examples include the East African rift and mid-ocean ridges where two ocean plates are moving apart, such as the regions near the Azores and Iceland.
