In a nutshell, a chemical change produces a new substance, while a physical change does not. A material may change shapes or forms while undergoing a physical change, but no chemical reactions occur and no new compounds are produced. And for an explanation on how to see the difference Look for an indication that a chemical change occurred. Chemical reactions release or absorb heat or other energy or may produce a gas, odor, color or sound. If you don't see any of these indications, a physical change likely occurred. Be aware a physical change may produce a dramatic change in the appearance of a substance. This doesn't mean a chemical reaction occurred.

In the agricultural practices cover plants are grown for the enrichment and the protection of the soil. They are not harvested to be sold as cash crops.

<h3>What are the cover crops used for?</h3>

Cover crops are grown in the agricultural land parts to maintain the soil fertility and quality so that the land will be safe from the invasion and attacks of pests and weeds.

They are generally grown after the reaping of cash crops and help in soil binding by preventing erosion from the water runoffs.
