Where is each type of plate boundary present?

Answer 1

-Transform boundaries occur where plates slide or, perhaps more accurately, grind past each other along transform faults. The relative motion of the two plates is either sinistral (left side toward the observer) or dextral (right side toward the observer). The San Andreas Fault in California is one example. -Divergent boundaries occur where two plates slide apart from each other. Mid-ocean ridges (e.g., Mid-Atlantic Ridge) and active zones of rifting (such as Africa's Great Rift Valley) are both examples of divergent boundaries. -Convergent boundaries (or active margins) occur where two plates slide towards each other commonly forming either a subduction zone (if one plate moves underneath the other) or a continental collision (if the two plates contain continental crust). Deep marine trenches are typically associated with subduction zones. The subducting slab contains many hydrous minerals, which release their water on heating; this water then causes the mantle to melt, producing volcanism. Examples of this are the Andes mountain range in South America and the Japanese island arc.

Answer 2

Mid-Atlantic Ridge and East African Rift--divergent plate boundaries.

Andes Mountains--oceanic to continental convergent plate boundary.

Himalaya Mountains--continental to continental convergent plate boundary.

Marianas Trench--oceanic to oceanic convergent plate boundary.

San Andreas Fault--transform plate boundary.

Answer 3

Divergent plate boundaries are found where plates are moving apart, such as the Mid-Atlantic Ridge. Convergent plate boundaries occur where plates are moving towards each other, leading to subduction zones like the Pacific Ring of Fire. Transform plate boundaries are where plates slide past each other horizontally, such as the San Andreas Fault.
