The rock formed from layers of sand with a fine grainy texture is called sandstone. Sandstone is a sedimentary rock composed primarily of sand-sized mineral particles, typically quartz or feldspar, cemented together by minerals such as silica or calcium carbonate. Its fine grainy texture indicates that it has undergone less weathering and transport compared to coarser sandstones. This type of rock is commonly found in environments such as deserts, riverbeds, and beaches.
Sandstone
Shale is formed as a result of many processes. The first process involves the weathering and erosion of existing silicate rock, usually igneous or metamorphic in nature, and what would normally appear in a weathering mountain range. The weathering of this rock creates clay and silt sized particles which are transported down slope by the erosion from wind, moving water, gravity, and ice. These small particles are carried the farthest from their point of origin, and settle out from suspension in the water or wind in a process known as deposition. As more and more sediment layers are added over great lengths of time, the particles of sediment are compacted by the weight from above and the clay particles become loosely interlocked into a rock with thin depositional layering - shale.

An early maturing, medium sized ans yellow skinned variety of Muskmelon grown in Maharashtra is called Suvarnakanya.
Silt particles cemented together form a sedimentary rock known as siltstone. Siltstone is composed mainly of silt-sized particles compacted and cemented over time. It has a fine-grained texture and is commonly found in layers or beds in sedimentary rock formations.
Claystone. Shale also contains clay sized particles mixed with silts.
Sandstone is a sedimentary rock made up of sand-sized grains of minerals or rock fragments. It can vary in size, from very fine to coarse grains. It is called "sandstone" because of its predominant composition of sand-sized particles that are compacted and cemented together over time to form the rock.
A conglomerate rock forms when gravel-sized sediments, such as pebbles and cobbles, are deposited in a high-energy environment, like a river or beach. Over time, the sediments become compacted and cemented together by minerals, creating a solid rock composed of different sized particles.
Shale is composed of very fine particles that are typically clay-sized, which means they have a diameter of less than 0.002 millimeters. These particles are compacted and cemented together to form the rock known as shale.
No. Ash consists of sand sized particles and smaller. Pebble sized particles are called lapilli.
Siltstone is a sedimentary rock composed of cemented silt-sized particles of quartz and feldspar, primarily.
Sandstone will have a gritty clastic texture, created by the cemented particles of sand sized particles of rock. You should be able to see the individual sand grains.
Siltstone is a type of sedimentary rock composed mainly of silt-sized particles. These particles are cemented together over time to form a solid rock. Siltstone has a fine-grained texture and is commonly found in geological formations where sediments have accumulated.
One characteristic that can help distinguish between sandstone and tuff is their composition. Sandstone is primarily composed of sand-sized mineral grains cemented together, while tuff is composed of volcanic ash and tephra fragments that have been compacted and cemented together. Tuff may also exhibit a finer texture due to the smaller size of volcanic particles compared to sand grains in sandstone.
Sandstone is a sedimentary rock made up of sand-sized mineral particles (usually quartz) cemented together. It typically has a granular texture and can range in color from white, tan, and yellow to red and brown. Sandstone often contains visible grains of sand and varying levels of porosity.
It depends on how you are defining the word 'soft'. Quartzite is the hardest and most durable of the three - no question there. Shale can be crumbled with the tap of a hammer. Some loosely cemented sandstone can be crumbled when squeezed hard enough with your hand and some is well cemented and quite hard.
