umm erosion?
glaciers move them downhill and scratch the surface of the valley from a river 'v' to a glacial 'u' they also move lots of rocks. rivers move rocks downstream the higher upstream the more rough and sharp edged they are, downstream they are smoother and rounder due to erosion.
smoother
Downstream speed refers to the rate at which data can be downloaded from the internet to your device. It is typically measured in megabits per second (Mbps) and is important for activities like streaming video, downloading files, or browsing the web. A higher downstream speed allows for faster downloads and smoother online experiences.
Because they are continuously eroded by the rushing water running past them.
Sediments move downstream through processes like erosion, transportation, and deposition by the force of water, wind, or ice. As water flows, it picks up and carries sediments, gradually depositing them as the energy of the water decreases. This continuous cycle of erosion, transportation, and deposition allows sediments to be transported downstream over time.
to reduce friction and make the object move smoother.
not the force of water, but gravity and density does
The best oil to use for sharpening stones is mineral oil. It helps lubricate the stone and prevent metal particles from clogging the pores, allowing for a smoother sharpening process.
You move them forcefully over parts and areas that you want to be smoother.
A mortar, the lime mortar in particular is a soft mortar that allows flexibility on stones to move. The mortar is a breathable mortar that can allow moisture to move freely.
Ancient discoveries, where people as long ago as 6,000 BC picked up alluvial stones from the ground that had been washed downstream by running water, running over volcanic pipes that brought the stones to the surface of the earth.
