The correct answer is: d) All of the above.
Punjab has a rich mineral resource base, with deposits of sand and gravel, clay, stone, and other minerals. These minerals are used in a variety of industries, including construction, manufacturing, and agriculture.
Sand and gravel are used in the construction of roads, buildings, and other infrastructure. Clay is used in the manufacture of bricks, pottery, and other products. Stone is used in the construction of buildings, monuments, and other structures.
The mining of these minerals has a significant impact on the economy of Punjab. The industry employs thousands of people and generates billions of rupees in revenue each year.
However, mining also has a number of environmental impacts. The extraction of minerals can lead to the destruction of forests and other ecosystems. It can also pollute water supplies and air quality.
The government of Punjab is working to mitigate the environmental impacts of mining. It has implemented a number of regulations to protect the environment. It is also working to develop alternative sources of building materials, such as recycled materials.
Despite the environmental challenges, the mining industry is an important part of the economy of Punjab. The government is committed to ensuring that the industry is developed in a sustainable manner.
Here is a brief explanation of each option:
- Sand and gravel are non-metallic minerals that are used in a variety of construction projects. They are used to make concrete, asphalt, and other building materials.
- Clay is a type of sedimentary rock that is formed from the weathering of other rocks. It is used in the manufacture of bricks, pottery, and other products.
- Stone is a type of rock that is formed from the consolidation of minerals. It is used in the construction of buildings, monuments, and other structures.
