Which is least affected by chemical weathering?
3 answers
Igneous rocks are typically least affected by chemical weathering compared to other types of rocks such as sedimentary or metamorphic rocks. This is because igneous rocks are formed through the cooling and solidification of magma or lava, and they have a more crystalline structure that is less prone to chemical reactions with water and atmospheric gases. However, it is important to note that the specific mineral composition of an igneous rock can still influence its susceptibility to chemical weathering.

a pile of tiles of feldspar
a chair made of plastic
a bridge made of iron rods

Out of the options listed, a chair made of plastic is typically the least affected by chemical weathering. Plastic is a synthetic material that is not easily broken down chemically by water, air, or other environmental factors. It is resistant to most chemical reactions and does not corrode or degrade easily.
Marble, on the other hand, is a metamorphic rock composed mostly of calcite, which can be prone to chemical reactions with acidic substances in the environment. It can be dissolved or eroded over time by acid rain or other acidic solutions.
Tiles made of feldspar, which is a type of clay mineral, can be affected by chemical weathering as well. Feldspar can undergo weathering processes such as hydration, hydrolysis, and dissolution when exposed to water, leading to the breakdown of the material.
Iron, as found in iron rods used in a bridge, is highly susceptible to chemical weathering. Iron easily reacts with oxygen in the presence of water and air, resulting in the formation of iron oxide, commonly known as rust. Rusting weakens the structural integrity of iron, leading to potential degradation.
Therefore, the chair made of plastic is typically least affected by chemical weathering compared to a marble statue, feldspar tiles, or an iron bridge.
