The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions. For example, an igneous rock such as basalt may break down and dissolve when exposed to the atmosphere, or melt as it is subducted under a continent. Due to the driving forces of the rock cycle, plate tectonics and the water cycle, rocks do not remain in equilibrium and change as they encounter new environments. The rock cycle explains how the three rock types are related to each other, and how processes change from one type to another over time. This cyclical aspect makes rock change a geologic cycle and, on planets containing life, a biogeochemical cycle.
The Archaea of cytoplasm contains ribosomes for the creation of cell proteins and it have a coiled ring of DNA.
In contrast to microscopic organisms, the cell divider and film can be firm and give the cell a particular shape,<em> for example, flat, rod-shaped or cubic.
</em><u>Qualities of the archaea-</u>
Cell dividers: for all intents and purposes all microscopic organisms contain peptidoglycan in their cell dividers be that as it may, <em>archaea and eukaryotes lack peptidoglycan.</em>
<em>Fatty acids: microscopic organisms and eukaryotes produce layer lipids comprising of unsaturated fats connected by ester securities to a particle of glycerol.</em>
