No by wind speed is the way to determine the strength.
Varves are best developed near glaciers because they represent light colored layers of coarser material deposited in the summer when the streams issuing from glaciers have more energy to erode coarser material compared to the fine silts and clay of the winter months when there is very little flow and very little erosion. They mostly occur in glacial lakes.
If the black hole had the same gravitational effects as the sun then the black hole wouldn’t effect the earth, we wouldn’t have light and everyone would most likely die in 10 minuites
Ok I'll send the answers soon
