Here is how one reference describes it [1]: Sea-floor spreading is driven by crust formation along the mid-ocean ridges, meandering undersea mountain ranges that span Earth like the seams of a baseball. Oceanic crust is continually produced by magma welling up along the centerlines of the mid-ocean ridges.
Watering the grass every single day for 15 minutes. This turns the lawn into a shallow-rooted water junkie that demands a water fix every day just to soldier on. Instead of watering shallowly every day for 15 minutes, water deeply once a week for an hour or so (or how ever long it takes to apply an inch of water). Your lawn will be healthier and more drought-tolerant.
1 Pour all the water into one can, which equals the amount of water your sprinkler system delivers in one hour.  Based on this number (inches per hour), you can determine how long the sprinkler must run to provide your lawn with the amount of water it needs. For example, in June, a typical Kentucky bluegrass lawn needs about 1.5 inches of water a week, which means you should water your lawn about a half inch three times a week.
