An avalanche takes place when ice and snow move down a slope with great speed. what effect does friction have on its rate of movement? a. friction causes the avalanche to move rapidly. b. friction creates a curved surface that decreases the speed. c. the speed of the avalanche decreases with increased friction. d. the speed of the avalanche increases with increased friction. e. friction does not have any effect on the avalanche.

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
