As India is colliding with Asia, the margin of Asia is experiencing significant deformation. What is happening to the rocks that are being deformed?

A) They are being subducted into the mantle
B) They are being melted to become magma plutons
C) They are being displaced to the southeast to make up Southeast Asia
D) They are breaking off to form microcontinents

Question 2

India has been colliding with Asia for roughly 50 million years, a process that has uplifted the Tibetan Plateau. However, although the margin of Asia has been intensely deformed, India has remained largely intact. Why is this the case?

A) Asia's margin is composed of soft materials such as shale and sandstone
B) There is a mantle plume beneath the Asian continent that softens the plate, permitting deformation
C) Asia's rocks are over 2 billion years old and are so dense they are sinking back into the mantle
D) Most of India is tough, durable, ancient shield material and is harder than the newer Asian material
