• sandstone and limestone

• marble and slate

• clay and shale

Quarrying is extracting

• rock and stone from the surface

• minerals from the surface

• minerals from deep mines

• rocks from underground

Metamorphic rocks are

• rocks from cooling of flowing lava

• formed from sediments

• rocks formed from changing of heat and pressure in the earth’s crust

• All of the above

Factors affecting decisions of extracting rocks and minerals are

• depletion rate

• supply and demand

• location

• geological conditions

Negative Impacts of mining on the environment include

• waste heaps

• dust and fumes from chimneys

• noise from explosives

• none of the above

Sanitary landfilling is

• biomediation

• alternating layers of refuse and soil

• landscaping

• land restoration

Managing the impacts of extraction include strategies like

• Biomediation

• landscaping

• greenhouses

• landfilling

Sustainable use and conservation of rocks and minerals can be done by

• New technological development

• Enforcing the legislation

• by just posting signs

• Increasing the efficiency of products

A good example of recycling industry is
