Answer 2

ANSWER:

The deposition on the leaves of the school compound consists of tiny dust particles while the soot deposited on leaves on roadside consists of carbon dioxide and carbon monoxide.

EXPLANATION:

The leaves in the school have to bear the dust and sand particles that may carried by action of wind or when children walk around in the campus. The roadside leaves get carbon dioxide and carbon monoxide depositions because of the vehicular pollution.

The vehicles that pass on the roads release carbon dioxide causing air pollution and these particles settle on the leaves.
