Conserving Natural Resources — Practice Quiz

Iron ore, Coal, Natural gas

Iron ore, coal, and natural gas are non-renewable because they take millions of years to form and cannot be replaced once used. Wind energy is renewable as wind continuously blows, and forest timber is renewable as trees can be replanted.

Deforestation, Indiscriminate mining, Sand extraction from rivers

Deforestation, indiscriminate mining, and sand extraction deplete natural resources. Tree plantation and water conservation help preserve resources rather than deplete them.

Stream encroachment, Tank and pond occupation, Forest clearing

Stream encroachment, occupying tanks and ponds, and forest clearing reduce water infiltration into ground, causing groundwater decline. Rainwater harvesting and well construction help maintain groundwater levels.

Coal, Stones, Sand

Coal, stones, and sand are mineral resources found in the earth's crust. River water and sunlight are not mineral resources - water is a natural resource and sunlight is an energy resource.
