Question

Q.7 Define the following.
1. Weathering
2. Galvanisation
3. Neutral
4. Insulators​

Answer 1

Weathering - Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. ... Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.

Galvanisation - Galvanisation or galvanization (or galvanizing as it is most commonly called) is the process of applying a protective zinc coating to iron or steel, to prevent rusting. The most common method is hot dip galvanizing, in which steel sections are submerged in a bath of molten zinc.

Neutral - Not supporting or helping either side in a conflict, disagreement, etc.; impartial.

Insulators - A substance which does not readily allow the passage of heat or sound.

1. Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.
2. Galvanisation or galvanization (or galvanizing as it is most commonly called) is the process of applying a protective zinc coating to iron or steel, to prevent rusting
3. having no strongly marked or positive characteristics or features.
4. An electrical insulator is a material in which the electron does not flow freely or the atom of the insulator have tightly bound electrons whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field.
