1. the sedimentary rock known as conglomerate typically forms in environments in which particles can become rounded, such as fast-flowing rivers. 2. an example of is when moving water slows down and particles being transported in the water begin to settle out (sediment) in a new location. 3. is a type of sediment that feels smooth to your fingers but gritty in your mouth. 4. the most common chemical sedimentary rock is

(1) Fluvial environment

(2) Deposition

(3) Limestone

(4) Sandstone

Explanation:

Conglomerates are those in which the particles are big and rounded. They are formed in the high energy condition, such as fluvial or beach environment having strong winds.Deposition takes place with the rate of transport of fluid or water. If the flow rate is high then the water carry sediments to a far extent, whereas if the flow rate is slow or it stops then the sediments get deposit.Limestone is comprised of calcium carbonate, so when we touch it with our fingers we feel a bit of smoothness and tastes like grit in mouth.Sandstone is the most common one, containing approximately 70-75% of all the sedimentary rocks on earth.
