Question

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 _______.

Answer 1

Answer: 1. high-energy

2. deposition

3. Silt

4. limestone

5. soluble

6. tectonic forces

7. before

8. faunal succession

9. nondeposition

10. coarser

Explanation:

Answer 2

Answer: (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.
