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.
