Because clay is harder and if you put water on sand then it will just sink in. Tehehehe
It isn't. There are large portions of the bottom of Lake Michigan that are covered in stones and boulders.
You can separate sand grains from salt grains by combining the mixture with water to dissolve the salt. The sand will settle at the bottom of the container, allowing you to pour off the salt solution. The sand can then be dried and collected.
A bed of salt lake that contains water at irregular periods is called a playa. The water that covers a playa slowly filters into the ground into groundwater systems or evaporates into the air, causing a deposition of salt, sand, and mud along the bottom and edges of a flat-bottomed depression.
When water is added to a salt and sand mixture, the salt will dissolve in the water, creating a saltwater solution. The sand, being insoluble, will remain as a solid at the bottom of the container. This allows for the separation of the two components through a process like filtration.
The material most likely exposed on the surface today that was formerly at the bottom of Lake Bonneville includes fine sediments such as clay and silt, along with layers of gravel and sand. As the lake receded, these sediments were left behind, forming the Great Salt Lake Desert and surrounding areas. Additionally, remnants of ancient shorelines and various geological formations may also be visible today, reflecting the lake's extensive history.
mix the salt and sand into a glass of water. The sand would settle at the bottom of the glass, and the salt would dissolve into the water. pour off the salt water, wait for the water to evaporate, and you will be left with salt, and sand.
1. Filtering the liquid sand remain on the filter. 2. The solution containing salt pass the filter; after the evaporation of water crystallized NaCl is obtained.
The bottom. Quicksand doesn't "lead" anywhere, it's basically just a lake with a lot of sand in it.
first mix them in water. sand wont dissolve in water. so it get distilled and settle down. but salt dissolves in water. after sand gets settled, gently pour off the water. the remaining is salt solution. when its heated water get evaporated and the salt remains.
pour water in the cup, the saw dust flouts up the sand stays at the bottom
Clay is the least porous of all soil types. It is the opposite of porous in comparison to sand.
