Write a summary about web cams and give me imformation about it

Web Cams are usually used to catch secret footage that is later posted all over the internet.  As you can see, on the internet you watch so many videos with that involve someone alone. How do people film and get the person caught on camera? Web Cam. Webcams are also used to see whoever is at your door or simply if anyone is trying to break into your home. For example, there is the ring. The ring is the product that is used to see if your home is in danger or not. It's a webcam that is installed all through your house.
 This is a short little essay to tell you about webcams. Hopefully, I help and you get a great grade! :)

Through the process of sedimentation,sediment is turned back to rock to form sedimentation.the process of sedimentation is: > deposition-where fragments were deposited into the river or sea under gravity or travelling agent such as wind or water. > sedimentation-the fragments deposited in the river sedimented and accumulate> compaction-the layers of fragments deposited undergoes compaction due to the weight if the upper layers> cementation-chemical substance of the fragments such as cement dissolved into the water and cement the other fragments together to form sedimentary rock.thus,cementation and compaction are the process.on the other hand, transformation only occur when a rock under goes metamorphism(compaction or extreme heat).while recrystillization occurs when a rock is melted and cooled down,which also requires metamorphism to take place.hope it !
