Question

The stone tools were quite significant in the growth and development of human civilisation. Are the rocks still important to humans today? Give reasons to support your answer.

Answer 1

Yes, rocks are still very important to humans today.

Reasons:

• Building Material: Rocks provide essential materials for the construction of houses, roads, bridges, and other structures. Granite, limestone, and sandstone are widely used for building.

• Source of Minerals: Rocks contain valuable minerals and metals like iron, copper, gold, silver, and aluminum, which are essential for making tools, machinery, and electronics.

• Soil Formation: Weathering of rocks produces soil, which is vital for agriculture and plant growth.

• Fossil Fuels: Rocks contain fossil fuels such as coal, petroleum, and natural gas, which are major sources of energy.

• Industrial Use: Rocks and their products are used in industries to make cement, glass, chemicals, and fertilizers.

• Decorative and Artistic Use: Marble and other rocks are used in sculptures, flooring, and decorative items.

• Water Storage: Some rocks store groundwater in their pores and cracks, forming aquifers that supply water for drinking and irrigation.
