What am I?

I am solidity
Formed from stone
Inert
Inanimate
Unliving
I have no soul
No cause to weep
No need to mourn
The sudden surge of passion
Never flows
I leave laughter
To others
Love to fools
I feel no pain
Hold no ambition
The sun may warm me
Frost can freeze
And wind erode
Yet still I stay
Unmoved
