Question

which of the following is a chemical and physical process?
volcanic eruptions
clearing of forests
cellular respiration
lighting strikes

Explanation:

Volcanic eruptions involve both physical processes like the movement of magma and chemical reactions occurring within the magma and during the release of volcanic gases. Clearing of forests is mainly a human - induced physical process with little chemical change at the large - scale process level. Cellular respiration is a biochemical process. Lightning strikes involve physical processes like electrical discharge and some chemical reactions such as the formation of nitrogen oxides in the atmosphere.

Answer:

A. Volcanic Eruptions
D. Lightning Strikes
