OBJECTIVE FORESTRY

Detailed explanation-1: -Natural aggregate consists of manufactured crushed stone and sand created by crushing bedrock, or naturally occurring unconsolidated sand and gravel.

Detailed explanation-2: -Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. For this to happen, the parcel of air must be saturated, i.e. unable to hold all the water it contains in vapor form, so it starts to condense into a liquid or solid form.

Detailed explanation-3: -The process of water changing from a gas to a liquid is called “condensation, ‘’ and when gas changes directly into a solid, it is called “deposition.” These two processes are how clouds form.

Detailed explanation-4: -Naturally-occurring aggregate deposits, whether sand and gravel or source rock for crushed stone, are formed by a variety of geologic processes. Volcanoes, earthquakes, glaciers, rivers and streams, and marine processes have each contributed to the formation of the materials we use as aggregate.
