because it has less surface contact with water
The slower the rate of cooling the larger the size of the crystals that can develop.
The main agents for chemical weathering are water and weak acids formed in water, such as carbonic acid (H2CO3). These agents dissolve some rocks, loosen mineral grains, form clay mineral, and widen fractures.
Rock salt, also known as halite, is a type of rock that dissolves in water. It is composed primarily of sodium chloride, which readily dissolves in water to form a saline solution.
No. Rock candy dissolves in water, which is different from melting.
Rock salt dissolves fastest in hot water.
To dissolve rock sugar in water, first crush the sugar into smaller pieces to speed up the dissolving process. Then, heat the water to a higher temperature (near boiling) and stir the sugar in until it completely dissolves. Alternatively, you can let the sugar sit in cold water for some time, stirring occasionally until it dissolves.
When all the grains in a rock are large and easy to see, the rock is described as "coarse-grained." This texture indicates that the rock has undergone a slower cooling process, allowing larger crystals to form. Coarse-grained rocks are often associated with igneous rocks, such as granite, where the individual mineral grains can be distinctly identified.

Limestone dissolves in water and travels.
such a rock may be of Gypsum (Magnesium sulphate) or common salt (sodium chloride ).
When a student dissolves sugar in water and then evaporates the water to make rock candy it is an example of a mixture. In science a mixture refers to the combination of different qualities.
The cooling rate of magma primarily controls the grain size of igneous rock. Faster cooling results in smaller grains, while slower cooling leads to larger grains. Other factors that can influence grain size include the composition of the magma and the amount of gas or water present during solidification.
