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.
Determining Your Sprinkler Output. The most important thing to do is to determine how much water your sprinkler delivers per hour. To do this, set out several empty cans around your yard and run your sprinkler for 20 minutes. Measure the average depth in the cans and multiply this number by 3 to find out how many inches your sprinkler delivers in an hour.
