True or false : rust is a product of mechanical weathering

False: Rust is a product of chemical weathering. Oxygen reacts with iron to form iron oxide (rust).

Mechanical weathering occurs when things are damaged physically like when ice makes a rock crack.

Chemical weathering is when things are disintigrated or damaged due to chemical reactions.
