Divergent boundaries are zones where tectonic plates move apart, primarily found along mid-ocean ridges, leading to the formation of new oceanic crust. They are characterized by underwater mountain ranges, rift valleys, volcanic activity, and frequent earthquakes. Key processes include upwelling of magma, cooling to form crust, and seafloor spreading.

2. Plate
Boundaries
• Plate boundaries are the
areas where the Earth's
tectonic plates meet. These
boundaries are dynamic
zones of geological activity,
resulting in a variety of
landforms and natural
phenomena.

4. LOCATION
Most divergent boundaries
occur along mid-ocean
ridges, where new oceanic
crust is created.

5. EXAMPLES
The Mid-Atlantic Ridge, the East
African Rift Valley, and the Iceland
Rift Valley are notable examples of
divergent boundaries.

8. LOGICAL FEATURES AT DIVERGENT BOUNDA
Mid-Ocean Ridges
•Underwater mountain ranges that form at divergent
boundaries.

9. LOGICAL FEATURES AT DIVERGENT BOUNDA
Rift Valleys
•Deep depressions that form on land as plates pull
apart, often accompanied by volcanic activity.

10. LOGICAL FEATURES AT DIVERGENT BOUNDA
Volcanoes
•Volcanic activity at divergent boundaries as
magma rises to the surface.

11. LOGICAL FEATURES AT DIVERGENT BOUNDA
Earthquakes
•Earthquakes are frequent at divergent
boundaries due to the movement and fracturing
of the plates.

1.
Upwelling
2.
Cooling
As magma
reaches the
surface, it cools
and solidifies,
forming new
oceanic crust.
3. Seafloor
Spreading
The newly
formed crust is
pushed away
from the ridge,
creating new
ocean floor.

14. EVENTS IN DIVERGENT
BOUNDARIES
Volcanic Eruptions
•Volcanic eruptions occur when magma rises
to the surface, releasing lava and volcanic
gases.

15. EVENTS IN DIVERGENT
BOUNDARIES
Earthquakes
•Earthquakes occur due to the fracturing and
movement of the plates along the divergent
boundary.

16. EVENTS IN DIVERGENT
BOUNDARIES
Formation of New Crust
•New oceanic crust is constantly being formed at
divergent boundaries through the process of seafloor
spreading
