A. Angin
B. Hujan
C. SuhuExplanation
Pelapukan secara fisis terjadi karena angin, hujan, dan suhu. Angin dapat memecahkan batuan dan mengikis permukaan benda-benda dengan membawa partikel-partikel kecil yang dapat merusaknya. Hujan juga dapat memecahkan batuan dan mengikis permukaan dengan air yang jatuh dengan tekanan. Suhu juga berperan dalam pelapukan fisis karena perubahan suhu yang ekstrem dapat menyebabkan kontraksi dan ekspansi pada benda-benda, yang pada gilirannya dapat menyebabkan pecah atau retaknya benda tersebut.Rate this question:
