Question

multiple - choice 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 lava flow, and chemical processes such as the release and reaction of various gases (e.g., sulfur - containing gases). Clearing of forests is mainly a human - induced physical process. Cellular respiration is a biochemical process mainly within cells. Lightning strikes involve physical processes like electrical discharge and heating, and also chemical processes such as the formation of nitrogen oxides in the atmosphere due to high - energy conditions.

Answer:

A. Volcanic Eruptions, D. Lighting Strikes
