The generic term for very small loose particles of hard broken rock or minerals is "sediment." These particles are created through the process of erosion, weathering, and deposition.
Microscopic particles are so small and hard to see with the human eye that is they are alive their movement would be small making it hard to determine whether they're alive or not.
No, grit will not dissolve in water as it is composed of small, hard particles such as sand or small stones. These particles will remain in the water without breaking down or dissolving.
he thought the atom looked like small, hard particles made of single material formed into different shapes. also that atoms always moving and that they form different materials by joining together. he contributed by having his idea particles always moving.
Rocks are hard because the atoms comprising the minerals which are present in rocks have formed a latticework which make them solid and very stiff. Solid, stiff objects require a significant load applied over a small area to undergo deformation.
Democritus
Yes, Democritus described that atoms are small, indivisible, and indestructible particles that make up all matter. He believed that atoms are constantly moving and combining to form different substances.
It is Democritus (440 B.C.) He proposed the idea that all atoms were small, hard particles made of one material and that everything can be broken down until there is nothing left but atoms. Course, this was long ago, so his theory wasn't exactly thorough enough..

Soft particles are small, flexible particles that can change shape easily. They differ from other types of particles, like hard particles, because they are more deformable and can move more freely in response to external forces.

John Dalton. N.B.: John Dalton [born: September 6, 1776; died: July 27, 1844, at age 67] was an English chemist and physicist who claimed matter was made up of tiny particles and that these particles were identical for any given kind of matter. Moreover, he claimed these particles were indivisible and could neither be created nor destroyed in any chemical process, only be altered in the manner they were grouped.
Democritus was an Ancient Greek philosopher who proposed the concept of atoms as the fundamental building blocks of nature. He believed that all matter is made up of tiny indivisible particles called atoms, which he described as eternal, unchangeable, and in constant motion. This idea laid the groundwork for modern atomic theory.
- All matter in composed of atoms and molecules (tiny particles) - The tiny particles are always in motion - Energy affects this motion -The particles interact -There is much space between these particles
The original Greeks thought of an atom was that it was a small hard chunk of the matter that it represented, not necessarily ball shaped. As atomic theory developed the models built to represent compounds often used sticks (or springs) and balls to represent the atoms and their bonds. These days an atom is thought to be mostly not there at all. A very small nucleus occupies the center made up of quarks which are hard to describe in physical terms, with an electron density cloud around it showing where the electron might be at any given time. So yes, the atoms are small. And no, they are not hard, at least not hard like a marble.
