Passive continental margins

Active continental margins

1. a) the east coast of North America is a passive continental margin

2. most of the Fe found on earth lies in the CORE

3. the red sea is marked by a transform boundary system

4. the average depth of ocean at abyssal plane is 5 kms ( 4km - 6 km)

5. these coasts with high seismicity and mountain building activity are known as Active Continental Margin
