The document discusses erosion, how it occurs through fluid flow like water, air and ice moving due to gravity, and examples of erosion problems in different locations. It notes deforestation has caused widespread soil erosion in Madagascar. About 50% of desertification and erosion in Ecuador is located in the western part of the country, particularly in the Andes Mountains, Galapagos Islands and provinces of Manabí and Esmeraldas. Ways to avoid erosion include planting trees, terracing, avoiding deforestation, and building containment walls.

2. What is erosion?
Erosion is the process by
which the surface of the
Earth gets worn.

3. Explain in detail how it
happens?
OThe key to erosion is
something called "fluid
flow."
OWater, air, and ice flow from
one place to another
because of the gravity.

5. Erosions problems in
Madagascar.
The Erosions problems that
Madagascar fell are:
ODeforestation on the highlands has
resulted in widespread soil erosion.
O During this 50 the River Delta
causes the Erosion.

6. Here is the Delta before and now
Before Now

8. Are there erosion problems
in Ecuador?
Yes here are erosions,
because Ecuador is
affected by desertification
and erosion.

9. The 50% of desetification
and erosion is located in the
western part of the country
(Esmeraldas,Manabí, Santo
Domingo).

10. Where exactly?
 The Andes Mountain in the
Highlands.
 Also in the Galapagos
islands, most in Santa Cruz.
 But were most is affected
is in Manabí and
Esmeraldas.

12. How can erosion be avoided?
You can do a lot of things to avoided the
erosion, for example:
OPlanting trees.
ODoing terrace.
ODo not cutting the trees.
OContention walls.
