Hello this is our report on els grade 11 , I hope someone will find this useful.

1. Presented by Cloie and Arjean

2. OUR MISSION
Is to explain how the products of
weathering are carried away by
erosion and deposited elsewhere...

4. WHAT IS WEATHERING?
Weathering is the process when large rocks are broken into
small pieces
Two types if it are:
. 1. Mechanical weathering or physical weathering
. 2. Chemical weathering

5. 1. Water- during the day
precipitation in a form of rain can
fill the cracks of the rock then at
night if the temperature is cold
enough water will freeze and
expand, as the water expands it
breaks the rock into small pieces

6. 3. Sun- as the sun heats down on earth moisture is evaporated
creating cracks in the rocks.
2. Wind-some wind gas are strong enough ro carry small pieces
of rock, when the particles carried by the wind strike large
rocks large rocks can be broken down

7. this occurs when a chemical break down the bonding holding
the rocks together, causing them to fall apart, forming into
smaller and smaller pieces
- Most common type of chemical weathering are oxidation
hydrolosis and carbonation.

8. example of carbonation;

9. Erosion is the movement of the pieces of rock , there's a number
of ways the particles can move.

10. 1. Water erosion water erosion is
the removal of surface material by
water from the earth crust and
transportal
-running waters can pick up rocks
and move them downstream erosion
in running water create river deltas

11. 2. Wind erosion can change the
shape of rocks and erosion also
happens when wind picks up
small particles and move them
,for example sand storms these
are large gust of wind carrying
sands

12. 3. Ice erosion: glaciers pick up rocks and move them around
as the glaciers move the trapped rocks scrape the earth's
surface creating valleys

13. CAN YOU IDENTIFY THIS
TYPE OF EROSION??

14. Deposition is the putting down or depositing of sediment, soil ,
and rocks in a new place
This can also change the shape of the land...
For example because of the water erosion there's a possibility
that the rocks from the running water will create another delta.
