Does it GAINS you? Failing an Exam

4. Does it DRAINS you or
Does it GAINS you? ‘Good luck’ ni crush

Does it GAINS you? Foods !!

Does it GAINS you? May malaman...

8. LEARNING OUTCOMES: explain the process of erosion.
describe how weathered materials
are transported and deposited.
describe the process of mass
wasting.
identify factors that influence
downslope movement.

9. What is a
EROSION?
Erosion is when soil, sand, or rocks
are worn away and moved from
one place to another by natural
forces like water, wind, ice, or
gravity.
Transport is the process by which
sediments are moved along from
the source to where they are
deposited.

10. Flowing Water
Moving Ice/Glaciers
Waves
Gravity
Wind AGENTS OF EROSION:

11. Water is the most common erosion agent. Millions of
tons of sediments are picked-up and transported
everyday along rivers, coasts, and oceans around the
world.
It moves materials.
Transports large objects with fast moving streams.
WATER EROSION

12. Wind Erosion
Wind - responsible for blowing away
loose sand, soil, and dust. It detaches
soil particles and transports them by
wind.
It happens mostly in dry places like
deserts.
Most effective in moving away
loose materials.
Example: The sand dunes in Paoay,
Ilocos Norte are formed through the
process of wind erosion.

13. Wave erosionWave erosion
Waves - It happens when
ocean waves hit the
shoreline again and again,
slowly wearing away rocks,
cliffs, and beaches.
The constant force of
water plus the sand and
rocks carried by the
waves act like
sandpaper, grinding and
breaking down the
coast.

14. Wave erosionWave erosion
Wave erosion creates
beautiful coastal
landforms that attract
tourists.
Example: The cliffs of
Palawan in the
Philippines are shaped
partly by wave erosion.

15. glacial
erosion Ice moves and carries rocks,
grinding the rocks beneath the
glacier
It happens in cold regions with
glaciers (mountains, polar areas).

16. glacial
erosion Movement/transport includes
plucking of material like rocks.
Example: Glaciers in the Himalayas

18. GRAVITATIONAL
EROSION Mass movement or Mass wasting -
downward movement of rock and
sediments, mainly due to the force of
gravity.
Movement from higher to lower
elevation.

19. FALL
What happens: Rocks or soil fall freely
through the air.
Speed: Very fast.
Example: Rockfall from a cliff.
Key Feature: Materials don’t stay in contact
with the slope.

20. slides
What happens: A large block of soil or rock
moves together along a flat surface.
Speed: Can be fast or slow.
Example: Landslide after heavy rain.
Key Feature: Movement is more or less in
one big piece.

21. FLOW
What happens: Soil, mud, or volcanic ash
flows like a liquid down a slope.
Speed: Can be slow (creep) or extremely
fast (mudflow, lahar).
Examples:
Mudflow: After a heavy rain on bare soil.
Lahar: Volcanic ash mixed with rainwater
flowing down a volcano.
Key Feature: Moves like a thick fluid.

22. What iS
DEPOSITION?
Deposition is the process of
sediments, soils, and minerals being
dropped or deposited in a new
place
