Explanations:Rajasthan, one of the largest states in India, is renowned for its rich mineral resources, particularly in the form of stone. Among these, marble and sandstone are the most significant and are widely exported to other countries. The state's geological composition and the presence of large deposits of these minerals make them important export commodities.
Marble is a metamorphic rock that is formed from limestone under high pressure and temperature. It is known for its beautiful, often veined, appearance and is used extensively in construction, sculpture, and decorative purposes. Rajasthan is home to several marble mines, particularly in the regions of Makrana and Nagaur, which produce high-quality marble. The marble from Makrana, for instance, is famous for its use in the Taj Mahal and is exported to various countries for its aesthetic and structural properties.
Sandstone, on the other hand, is a sedimentary rock composed of sand-sized mineral particles or rock fragments. It is widely used in construction, landscaping, and as a building material due to its durability and aesthetic appeal. Rajasthan has vast deposits of sandstone, particularly in the regions of Kota and Jodhpur, which are known for their high-quality sandstone. The sandstone from these regions is exported to other countries for use in construction and decorative purposes.
While Rajasthan does have deposits of other minerals such as silver and gold, these are not as significant in terms of export as marble and sandstone. The state's economy benefits greatly from the export of these stone resources, which are in high demand due to their quality and versatility. Therefore, the correct answer is that marble and sandstone are the minerals exported from Rajasthan to other countries.
