how does the water cycle influence the rock cycle in an area similar to the grand canyon?
a
large amounts of flowing water increase the rate of weathering and erosion.

b
too much rain soaking into the ground slows the rate of weathering and erosion.

c
sudden evaporation of water removes moisture from rock layers in the canyon walls.

d
decreased rainfall makes the rocks hard and brittle, causing them to crumble into pebbles.

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?
