GENERAL GEOLOGY

Detailed explanation-1: -Detailed Solution. The correct answer is Corrosion. There are different types of chemical weathering processes such as solution, hydration, carbonation, oxidation, reduction, and biological. Hence corrosion is not a type of chemical weathering.

Detailed explanation-2: -Oxidation is another kind of chemical weathering that occurs when oxygen combines with another substance and creates compounds called oxides. Rust, for example, is iron oxide.

Detailed explanation-3: -What Are the Types and Examples of Mechanical Weathering? In general, geologists identify 5 main types of mechanical weathering: Thermal expansion, frost weathering/wedging, exfoliation, abrasion, and salt weathering.

Detailed explanation-4: -Which process is not mechanical weathering? Water flowing over rocks.

Detailed explanation-5: -Freeze-thaw weathering or Frost Wedging. Exfoliation weathering or Unloading. Thermal Expansion. Abrasion and Impact. Salt weathering or Haloclasty.
