Questions & Answers about A parede ficou rachada por causa do sismo.
Why use ficou instead of foi or estava here?
Why is the participle rachada feminine here?
Could I just use pelo sismo instead of por causa do sismo?
Yes, you could say pelo sismo (by the earthquake), which treats the earthquake as the direct agent of the action. However, por causa do (because of the) is very natural here because it highlights the earthquake as the underlying reason or trigger for the wall's new state.
I have seen the word terramoto for earthquake. Why use sismo here?
