Answer: (1) Fluvial environment
(2) Deposition
(3) Limestone
(4) Sandstone
Step-by-step 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.
