Timing, exact rates and weather conditions are extremely important. A good option is to hire a professional lawn care specialist to apply chemicals. Spot spraying with a selective broadleaf herbicide (weed killer for lawns) is a good way to kill your weeds without damaging your lawn. I spot spray (as opposed to applying herbicides to the entire lawn) most of the lawns that I manage because it uses less chemicals and is the responsible approach to take.
Transfer of Heat. Magma can also be created when hot, liquid rock intrudes into Earthâs cold crust. As the liquid rock solidifies, it loses its heat to the surrounding crust. Much like hot fudge being poured over cold ice cream, this transfer of heat is able to melt the surrounding rock (the âice creamâ) into magma. Transfer of heat often happens at convergent boundaries, where tectonic plates are crashing together.
There are three basic ways in which heat is transferred. In fluids, heat is often transferred by convection, in which the motion of the fluid itself carries heat from one place to another. Another way to transfer heat is by conduction, which does not involve any motion of a substance, but rather is a transfer of energy within a substance (or between substances in contact). The third way to transfer energy is by radiation, which involves absorbing or giving off electromagnetic waves.
