It is the Archaea. The Archaea constitute an area and kingdom of single-celled microorganisms. These microorganisms are prokaryotes, which means they have no cell core or some other layer bound organelles in their cells.
Archaea are microorganisms that characterize the breaking points of life on Earth. They were initially found and depicted in extraordinary conditions, for example, aqueous vents and earthly hot springs. They were additionally found in a different scope of profoundly saline, acidic, and anaerobic conditions.
A landform is a feature on the Earth's surface that is part of the terrain. Mountains, hills, plateaus, and plains are the four major types of landforms. Minor landforms include buttes, canyons, valleys, and basins. Tectonic plate movement under the Earth can create landforms by pushing up mountains and hills.
A plain is nothing but a low-lying relatively flat land surface with very gentle slope and minimum local relief. About 55% of the earth's land surface is occupied by plains. Most of the plain have been formed by deposition of sediments brought down by rivers.
Plateaus are elevated flatlands. In other words, it is flat land which is standing high above the surrounding area. Furthermore, they may have one or more sides with steep slopes. Also, depending upon the plateau, their height varies from a few hundred meters to several thousand meters.
