Explanation:
5. Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rusting is the common term for corrosion of elemental iron and its alloys such as steel.
6. Biological weathering only refers to weathering caused by organisms -- animals, plants, fungi and microorganisms such as bacteria. While certain forms of biological weathering, such as the breaking of rock by tree roots, are sometimes categorized as either physical or chemical, biological weathering can be either physical or chemical. Biological weathering can work hand in hand with physical weathering by weakening rock or exposing it to the forces of physical or chemical weathering.

5. Rust is a chemical reaction (oxidation) of iron that occurs over a period of time as the bare metal surface comes in contact with oxygen present in the air or water. Rust "eats" away the metal, making it weak and fragile. ... Oxygen is responsible for the oxidation of iron and therefore forms rust. Get it? OXI-dation and OXY-gen
6. Weathering is the breaking down or wearing away of rocks where they are. It does not happen because they move or collide with each other. One type, biological weathering, is caused by animals and plants. For example, rabbits and other burrowing animals can burrow into a crack in a rock, making it bigger and splitting the rock.

You may have seen weeds growing through cracks in the pavement. If you have gone for a walk in the countryside, you may even have seen bushes or trees growing from cracks in rocks or disused buildings. This is because plant roots can grow in cracks. As they grow bigger, the roots push open the cracks and make them wider and deeper. Eventually pieces of rock may fall away.
Hey Chintu, I kept it a bit simple with examples. But the answer doesn’t need to be complex to be brainliest, it should be understandable.
PLEASE MARK AS BRAINLIEST ANSWER, PLEASE!!!!!!!!
