You can use Florida-friendly fertilizing practices to help protect water quality while having a beautiful lawn. If you fertilize your lawn before a heavy rain, much of the fertilizer will be washed directly into surface water or stormwater systems that drain to our local springs, lakes, rivers and bays.Recent studies have shown that rising nitrate levels in many local water bodies can be traced to fertilizer.ou can use Florida-friendly fertilizing practices to help protect water quality while having a beautiful lawn.

Another misconception has to do with what makes something chemical or physical. Physical sunscreens contain zinc oxide or titanium dioxide, and chemical sunscreens contain micronized ingredients like avobenzone, Dr. Day explains. As for the belief that natural, physical sunscreens are the ultimate way to go? People think that if it's natural rather than chemical, it means it's better.
Another big difference between physical and chemical change is the speed of transformation. Physical change occurs faster and sometimes instantaneously. Most chemical changes, on the other hand, take longer time to become discernible. You can crumple a tin can and you will immediately see physical changes. But corrosion of tin can occurs very slowly; it will take a long time before you see the appearance of rust on the can. There is a wide difference between physical and chemical changes. With physical change, you are not transforming the original molecular composition of the substance. But with chemical change, the molecular structure is being transformed thus you will get a new substance.
