1. Where are the fold mountains formed? Any near Malaysia?
The fold mountains are formed near collisionary boundaries where the plates move together to force sedimentary rock into fold mountains. There are some fold mountains in Malaysia, Mount. Kinabalu is a good example.
2. How are they formed?
Firstly, rivers and seas carry sediments into geosynclines. The sediment soon accumulates and is compressed into sedimentary rock like limestone and sandstone. When the plates began moving towards each other they, the sedimentary rock cannot be compressed or destroyed so it is forced upwards forming fold mountains.
3. Do they change over time?
Yes, I predict that they will change over time. As the plates are constantly moving, the fold mountain may rise or change shape
