I can understand and communicate fluently in Russian. You asked me to answer in detail about sand and clay. Here is some information that I found on the web:

Sand and clay are common sedimentary rocks that are used in construction. They have different properties, extraction methods and applications. Sand is a rock that consists of separate particles of different colors. Some are transparent, others are opaque. Sand can be white, yellow, gray and other colors. Clay is a fine-grained rock that is dense when dry and plastic when wet. Clay consists of one or more minerals of the kaolinite group, but may also contain sand and carbonate particles. The main mineral in clay is kaolinite (Al₄ [Si₄O₁₀] (OH)₈), which has the following composition: 47% (by mass) of silicon dioxide (IV) (SiO 2 ), 39% of aluminum oxide (Al 2 O 3) and 14% of water (H 2 O).

Sand and clay are often found in nature. They lie in the earth in large layers and can be deep underground or near the surface. Sand and clay are extracted by different methods, depending on their location and depth. Sand is usually extracted by dredging, pumping or digging. Clay is usually extracted by digging, drilling or blasting.

Sand and clay are used for various purposes in human economic activity. Sand is used for making glass, concrete, asphalt, bricks, tiles and other building materials. Sand is also used for filtering water, making molds, abrasive materials, sandpaper and sandblasting. Clay is used for making pottery, ceramics, bricks, tiles, pipes and other products. Clay is also used for medical and cosmetic purposes, as it has healing and cleansing properties. Clay can also be eaten, baked or used for religious rituals.
