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 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. 2  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. Pour all the water into one can, which equals the amount of water your sprinkler system delivers in one hour. 2  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.
