SIAL
The radius of the core of the Earth is about
3500 kms
4500 kms
5300 kms
4450 kms
The formation of mountains are the result of
Divergent boundaries

Choose the correct statement
SIAL is in solid state, SIMA is in liquid state.
SIMA is less denser than SIAL
SIMA "floats" on SIAL
The lighter SIAL is considered as "floating" on denser SIMA layer.
