What am I Riddles

Many things may come and go
But I stand firm and still,
For me staying in my place
Is of but, god’s will.
My weathered face is battered and cracked
And with stinging salt water, my foot is slapped.
A gull on the wind, in carried in and lands on my green hair.
I have a foot, I have a face
But no body or chest to fill their place.

What am I?
