Answer:

B. Hardness

Explanation:

Physical properties of a substance is defined as the properties which can be observed or measured without changing the composition of matter.

Physical properties include odor, appearance, color, texture, boiling point, melting point and many others.

Hardness is a physical property of a substance as it describes the  resistance of substance to deformation and can be observed by simple touch or without changing the composition of matter.

Hence, the correct option is B.

The negative effects of tilling include _____. A increased soil erosion B reduced soil drainage C reduced need for energy input
Vikentia [17]

Answer:

A

Tilling agitates the topsoil and removes ‘unnecessary’ vegetation so the main crop can grow without competition. Tilling improves soil aeration and drainage for plants to grow well.  Nonetheless, it can lead to other consequences such as soil erosion because it loosens the soil and makes it easy to be carried away by wind and water.
