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.
Water your lawn for about an hour immediately after you rake. Water your lawn for at least 30 minutes a day for seven days to make sure the seeds get enough water. Wait as long as you can to mow the tall grass -- at least four to five days -- so the seeds have time to become stable in the soil.
