In this lesson, Minerals, you will explore various characteristics of minerals to identify them as you learn how Earth's natural processes and cycles from and distribute minerals. To identify most minerals, a combination of several tests or the use or multiple properties is required. But some minerals have distinctive properties that make identification relatively easy. For example, calcite fizzes when a drop of diluter hydrochloric acid is applied. No mineral besides calcite reacts to the acid in this way. Other minerals can be identified by distinctive taste, smell, or feel. For example, halite has a salty taste (but we will not be tasting minerals), and talc has a very distinctive feel - it feels soapy or greasy.
This weeks objectives are to:
- Identify characteristics of minerals and explore their properties.
- Identify the processes that result in the formation of minerals.
- Explain the distribution of minerals resources on Earth.
