Earthquake is the common
geologic activity of the types of
convergent boundary we
experience here in Davao City.
What do you do during an
earthquake?

Based on the map answer the following
questions:
1. Plate Y is an oceanic
plate. When it converges
with the continental
Plate X, what will
happen?
2. Between Plates Y and X,
which one will undergo
subduction?

Fill each blank with the correct word found in the parenthesis.
• As continental plate converges with an oceanic plate, the (1) __________
(continental, oceanic) plate dives under the (2) ___________ (continental,
oceanic) plate. The process of diving towards the mantle is called (3)
_________ (subduction, floatation).
When two oceanic plates converge, the denser plate subducts. Once its
leading edge reaches the mantle, it melts
into a (4) __________
(magma, crust), builds up a pressure that makes it push the ground above
it, forming a (5) __________ (volcanic island, mountain).
The convergence between two continental plates results to a landform
called (6) ___________ (volcanic arc, mountain ranges). Since both plates
have the same densities, no plate subducts under the other. There is no (7)
___________ (volcano, mountain) formation. However, since the ground
moves, a phenomenon called (8) ____________ (earthquake, storm) may
be felt in nearby places.
