Weathering and Erosion
The Golden Gate Bridge has to be repainted ever 10 to 20 year because of the effect of rust. To prevent rusting they use a special paint that help prevent rust. The paint that they use has zinc in it to prevent rusting. The bridge gets rusty because of the fog. The fog is made from the ocean. The fog has lots of salt particles.
