What This Module is About
Introductory Message
Welcome to the Science 10 Alternative Delivery Mode (ADM) Module on Plate
Boundaries.
This module was collaboratively designed, developed and reviewed by educators from

Fig. 1 Convergent boundary
What’s New
Divergent boundaries are the region where crustal plates are moving away from
each other and in opposite directions. This either happens at mid-ocean ridges (the
so-called seafloor spreading) or at rifted continental margins.
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.

Activity 1: Am I Right?
Instructions: Refer your answer on the figure shown above. Write yes if the
statement is correct, and write no if the statement is wrong.
1. The motion of divergent plate boundary is spreading. _______________
2. Volcanic activity is present in divergent boundary. __________________
3. Oceanic lithosphere is formed in divergent plate boundary. ___________
What Is It
The occurrence of most seismic activity is due to the movement in the narrow
zones along plate boundaries. It occurs at the three type of plate boundaries –
divergent, convergent, and transform.
As the plates move past each other, pressure builds up. When the plates finally
give and slip-up due to the increased pressure, rapid release of energy as seismic
waves, causing the Earth to vibrate called earthquake.
Some of the plates have ocean water above them. Other plates include
continents, and some plates include both continents and ocean. The movements of
the plates help shape the geological features of our planet. The three main types of
plate movements include: The Earth’s lithosphere, which comprises the crust and
upper mantle, is made up of a series of pieces, or tectonic plates that move slowly
over time.

What’s In
In the previous lesson, you have learned about two plates are moving away
from each other, we call this a divergent plate boundary. Along these boundaries,
magma rises from deep within the Earth and erupts to form new crust on the
lithosphere. Most divergent plate boundaries are underwater and form submarine
mountain ranges called oceanic spreading ridges.
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.

Divergent plate boundaries are in continental and oceanic lithosphere. Results
that are found at a divergent boundary between oceanic plates are a submarine
mountain range like Mid-Atlantic Ocean Ridge, volcanic activity in the form of fissure
eruptions, shallow earthquake activity and widening ocean basin. When continental
plates converge, the breaking of the crust into several segments leads to the formation
of down faulted valleys called rift valleys.

of fissure eruptions, shallow earthquake activity and widening ocean basin. When
continental plates converge, the breaking of the crust into several segments leads to
the formation of down faulted valleys called rift valleys. As the valleys continue to
spread it will develop into a linear sea.
