Topic 6: Lesson 3 - Mineral Resources

What are three ways that minerals can form? (CHOOSE THREE)

• from gases that condense into solids

• from dripping water

• from cooled magma

• from elements in solutions that crystallize

• from organic materials

Order the steps of mineral formation from beginning to end.

• a solution forms from a liquid and dissolved substances

• a warm solution flows through cracks in rocks

• elements and compounds crystallize

• elements and compounds leave as the solution cools

Gold, quartz, and talc are minerals. Copper and iron are types of ore.

What is the difference between minerals and ores?

• A mineral is a non-living, solid substance that can be extracted from

  the ground. Ore is a type of mineral made up of metals.

• An ore is non-living and solid with little value unless it occurs in

  large amounts, in which case it is a mineral.

• A mineral is a valuable form of ore that can be extracted from the

  ground.

• A mineral is a non-living, solid substance made of elements. Ore is

  a large deposit of one or more valuable minerals in the ground.

Some minerals are evenly distributed around the planet, while other

minerals are quite rare. Why are some minerals so rare and unevenly

distributed?

• Certain minerals form only under high heat and pressure that

  develop near volcanoes.

• Certain minerals form only in Earth’s crust, so they are difficult to

  locate.

• Certain minerals form only in specific climates, and not all climates

  are the same around the world.

• Certain minerals form only in the extreme heat found at the bottom

  of lakes and rivers.

Describe two ways minerals are used

by people. (CHOOSE TWO)

• Minerals are used to build buildings and electronics.

• Minerals are used to create electricity.

• Minerals are used to make jewelry.

• Minerals are used to power cars.

How does the increasing human population affects mineral use?

• Fewer minerals will be mined.

• Demand for products made from minerals will decrease.

• There will be no affect on mineral use if the population grows.

• There will be a larger demand for products made from minerals.

What are negative effects of mining for minerals and ores? (CHOOSE TWO)

• Minerals are nonrewable resources, so could eventually run out.

• Minerals are renewable resources and will always be available.

• Mining can cause damage to habitats.

• Mining does not disrupt the land.
