Question

What do these two changes have in common? Erosion caused by wind, carving a piece of wood.

A) Both are physical changes
B) Both are chemical changes
C) Both involve mechanical processes
D) Both result in the formation of new substances

Answer 1

The two changes, erosion caused by wind and carving a piece of wood, have in common that they both involve mechanical processes.

Step-by-step explanation:

The two changes, erosion caused by wind and carving a piece of wood, have in common that they both involve mechanical processes. In both cases, physical forces are exerted on the materials, causing them to change in appearance or shape without the formation of new substances. Therefore, option C) Both involve mechanical processes is the correct answer.
