Question

what type of weathering is the observation below? (one word, no spaces) rocks become smoothed with rounded shapes as shown below. your answer what type of weathering is the observation below? (one word, no spaces) potholes form on the roads in the winter in cold regions. your answer what type of weathering is the observation below? (one word, no spaces) iron atoms combine with oxygen to form iron oxide

Explanation:

Weathering can be physical (mechanical), chemical, or biological. When rocks become smoothed with rounded shapes, it is due to physical weathering from processes like abrasion. Potholes forming on roads in winter in cold - regions is also physical weathering, mainly due to freeze - thaw cycles. Iron atoms combining with oxygen to form iron oxide is a chemical reaction, so it is chemical weathering.

Answer:

1. physical
