Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The boundary where two plates are moving apart is a
A
convergent
B
divergent
C
transform
D
None of the above
Explanation: 

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. The Mid-Atlantic Ridge is an example of divergent plate boundaries .

Detailed explanation-2: -Divergent (Spreading):This is where two plates move away from each other. Molten rock from the mantle erupts along the opening, forming new crust. The earthquakes that occur along these zones, called spreading centers, are relatively small.

Detailed explanation-3: -Plates move apart from each other along divergent boundaries. In the ocean basins these boundaries are the mid-ocean ridges, where new oceanic crust forms. Where continents are pulled apart, large gaps, or rift systems, develop.

Detailed explanation-4: -There are two types of divergent boundaries, categorized by where they occur: continental rift zones and mid-ocean ridges.

Detailed explanation-5: -In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.
