A ppt for the topic magmatism in earth science.

2. 1. What do you observed from the video?
2. What happened when the heat and
pressure at the center of the earth build
up?
3. What is the term used in referring to
the red molten particles that oozed from
the inner part of the earth up to the
surface?
4. How does magma form?

3. MAGMATISM

4. Learning Targets:

5. MAGMA

6. What is the difference
between magma and
lava?

7. Magma Vs. Lava

8. MAGMATISM

9. Where does the
formation of magma
takes place?

10. ASTHENOSPHERE

12. How is magma formed?

13. Partial
Melting
In this process, different minerals
in rock melt at different
temperature and pressure.
Another factor being considered in
this process is the addition of
volatile materials such as water
and carbon dioxide.

15. What are the requirements
needed for the partial
melting to occur?

16. 1. An increase in temperature.

17. 2. A decrease of pressure

18. 3. Addition of volatiles

19. Now, let us see what
