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.
You should water around 10 to 15 minutes every other day or until you start to get runoff. water in the early morning this will allow more water to get absorbed and not to evaporate. If you have gear driven rotors you need to increase the run time. Hope this helps. Here is a link that might be useful: help_site.
