10. Guess the types of mountains…

11. For a more holistic view of mountains…
So what exactly are the processes that take place to form these mountains?
Dome mountains
Magma pushes up but doesn't actually crack through the surface, you can get a dome mountain
Without erupting onto the surface, magma pushes up overlaying rock layers
Cools and forms hardened rock as source moves away
Uplifted area created by rising magma is called a dome
Over long periods of time, erosion wipes away the outer layers of the mountain, exposing the dome-shaped cooled magma of harder rock

12. For a more holistic view of mountains…
So what exactly are the processes that take place to form these mountains?
Plateau mountains
Large flat areas pushed above sea level by forces within the Earth or formed by layers of lava
Plateau mountains are often found near folded mountains
As years pass, streams and rivers erode valleys through the plateau

13. So what exactly are the processes that take place to form these mountains?
Volcanic mountains
Self-explanatory!
More details in the future lessons!

14. Mountain Building 3 stages accumulation of sediments
rock deformation and crustal uplift
a period of crustal uplift caused by isostatic rebound and block-faulting

15. Stage 2: Rock Deformation and Crustal Uplift
Fold mountains
Fold mountains are formed when two plates collide head on
Edges of each tectonic plate crumple and buckle
Monocline, syncline, anticline,

16. Stage 3: Crustal Uplift caused by Isostatic Rebound and Block-Faulting

17. Stage 3: Crustal Uplift caused by Isostatic Rebound and Block-Faulting
Fault-block mountains
Faults named according to type of stress that acting on rock and nature of the movement of the rock blocks either side of the fault plane
Normal (tensional)
Reverse (compressional)
Graben (tensional, subsidence)
Horst (compressional, uplift)
Transform
What landform does faulting remind you of?
