8-3.5 Summarize the importance of minerals, ores, and fossil fuels as Earth resources on the

basis on their physical and chemical properties.

Key Vocabulary:

• Physical properties, chemical properties, minerals, ores, and fossil fuels.

III. Big Ideas:

• Earth resources (minerals, ores, and fossil fuels) have properties that make them important and useful.

• Properties that determine the usefulness of an ore or mineral may be identified using a chart, diagram or dichotomous key.

Big ideas

• The two properties are physical (hardness, luster, color, texture, cleavage & fracture, and density) and chemical (ability to burn and the reactivity to acids).

• Minerals are natural, solid materials found on Earth that re the building blocks of rock; each has a certain chemical makeup and set of properties that determine their use and value.

Big ideas

• Ores are mineral that are mined because they contain useful metals or nonmetals.

• Fossil Fuels are natural fuels that come from the remains of living thing: fuels give off energy when they are burned.

Essential Questions:

• 1. Why are minerals important resources?• 2. Why is an ore considered important?• 3. Why are fossil fuels considered

important?• 4. How would you compare and contrast a

mineral, an ore, and a fossil fuel?• 5. What properties would make an Earth

resource important?

The two types of properties are:

• · Physical properties; for example, hardness, luster, color, texture, the way a mineral splits, or density

• · Chemical properties; for example, the ability to burn, the reactivity to acids

Three common Earth resources that have importance based on their properties are:

Minerals

• · Natural, solid materials found on Earth that are the building blocks of rock; each has a certain chemical makeup and set of properties that determine their use and value.

Ores

• · Minerals that are mined because they contain useful metals or nonmetals.

Ores examples

Fossil fuels

• · Natural fuels that come from the remains of living things; fuels give off energy when they are burned.
