Sedimentary rocks. Sandstone is a common example of a sedimentary rock that is formed from the accumulation and cementation of sand-sized grains of mineral and rock fragments.

Volcanic particles about the size of rice grains are called volcanic ash. Ash is made up of small rock and mineral fragments that are expelled during a volcanic eruption.
The grain property of rock fragments refers to the size, shape, and arrangement of mineral grains within the rock. It is important for determining the rock's texture and can provide information about the rock's formation history and the conditions under which it was formed. Grain size can range from fine (tiny grains) to coarse (larger grains), impacting the overall appearance and characteristics of the rock.
Rocks are composed of one or more minerals, while grains are small, individual particles of a mineral. Rocks can be made up of different types of minerals and have a variety of sizes and shapes, while grains are typically uniform in composition and size. Rocks are larger and can be made up of multiple grains, whereas grains are individual, tiny fragments.
Sedimentary rocks are formed from the rock fragments that are made when a rock is eroed. Theese rock fragments are transported (carried away) from the rock face, usually by streams or rivers. As they are transported by the water, the rock fragments knock against each other and wear away. When they become very small they are called grains
Mineral grains are the individual crystals that make up a rock or mineral. They form through a process called crystallization, where minerals precipitate out of a solution or magma and grow into distinct crystal shapes. These grains can vary in size, shape, and composition depending on the specific conditions under which they formed.
