Josh rolled a bowling ball down a lane in 2.5 seconds. The ball travelled at a constant acceleration of 1.8 m/s/s down the lane and was traveling at a speed of 7.6 m/s by the time it reached the pins at the end of the lane.

How many meters of the rock wall eroded between 1910 and 1927?

As air temperatures increase, evaporation increases. Warmer temperatures also increase the capacity to absorb water vapor. More water vapor in the atmosphere accelerates the greenhouse effect.
