Continental Drift
What land feature was formed by the Indo-Australian and Eurasian Plates?
Himalaya Mountains
Earthquakes
When rock is physically broken into smaller pieces.
Mechanical Weathering
What layer would you find an old fossil?
The very bottom layer.
What is it known as when rock is physically broken into smaller pieces?
Mechanical weathering
This is formed when an oceanic plate is subducted beneath a continental plate.
