Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What type of boundary exists when 2 plates are pulling apart?
A
Convergent
B
Transform
C
Obtrusive
D
Divergent
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: -There are two types of divergent boundaries, categorized by where they occur: continental rift zones and mid-ocean ridges.

Detailed explanation-3: -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-4: -False, because the correct statement is: There are three types of divergent plate boundaries, namely continental-continental, oceanic-continental, and oceanic-oceanic.

Detailed explanation-5: -When plate divergence occurs on land, the continental crust rifts, or splits. This effectively creates a new ocean basin as the pieces of the continent move apart. In continental rifting, magma rises beneath the continent, causing it to become thinner, break, and ultimately split apart.
