The answer is conglomerate. Clastic sedimentary rocks such as Breccia, conglomerate, sandstone, and shale are formed from mechanical weathering debris. Chemical sedimentary rocks, such as rock salt, iron ore, chert, flint, some dolomities, and some limestones, form when dissolved materials precipitate from solution. Conglomerate is a coarse-grained clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel-size clasts, e.g granules, pebbles, cobbles, larger than 2mm in diameter.
The cell membrane is a biological membrane that separates the interior of all cells from the outside environment which protects the cell from its environment.
if we`ll not classify living beings then it`ll become difficult to study all of beings one by one. In order to make their study easier biologists have classified all living beings into five major groups.
There are more earthquakes on the West coast of the United States, because the boundaries of the North American, Pacific, and Juan de Fuca tectonic plates are located there. As the edges of the plates slide past or are forced under each other, the movement creates earthquakes
Due to the overproduction of offspring with only finite resources, species begin to engage in competition for survival. In order to increase their chance of survival, certain species will begin to develop genetic variations that allow them survival advantages.
