What is it called when softer rock weathers away and leaves harder rocks behind
These minerals are called evaporites.
The rock likely contains the mineral talc, which is known for leaving a white streak when scratched against a surface. Talc is commonly used in the production of powder products such as baby powder and cosmetics.
What is it called when softer rock weathers away and leaves harder rocks behind
weathering is wind erosin what it does is when wind blows it leaves behind pebbles and boulders.
The presence of white powder on basement walls could be caused by efflorescence, which occurs when water seeps through the walls and leaves behind mineral deposits as it evaporates.
Cocaine is an expensive white powder that is derived from the leaves of the coca bush.
The rock formed when water evaporates and leaves minerals behind is called evaporite. This process typically occurs in arid environments where evaporation rates exceed precipitation rates, leading to the concentration and eventual precipitation of dissolved minerals. Common evaporite minerals include halite (rock salt), gypsum, and calcite.
The rock is called a glacial erratic when it is left behind by a glacier, and is of a completely different material composition than the rocks on which it was deposited.

To find the streak of a rock, you can rub the rock against an unglazed white porcelain tile to observe the color of the powder left behind. The color of the streak can help identify the minerals present in the rock.
