Study Notes
Mineral Definition & Requirements
- Synthetic substances, like plastics, are not naturally occurring, thus not classified as minerals.
- A non-silicate mineral is calcite, which is the major component of limestone.
- A substance must be naturally occurring to be classified as a mineral.
Mineral Properties
- Hardness measures a mineral's resistance to scratching.
Earth's Spheres
- The hydrosphere regulates climate, supports various ecosystems, and sustains life through hydration.
- The atmosphere, a gaseous envelope, primarily consists of nitrogen (78%) and oxygen (21%).
- The lithosphere, the rigid outer layer of the Earth, includes the crust and uppermost part of the mantle.
- The biosphere is comprised of all living organisms on Earth.
Sphere Interactions
- The biosphere interacts with other spheres by inhabiting, influencing, and shaping them. For example, plants absorb water (hydrosphere) and release oxygen (atmosphere).
- The hydrosphere is significant for its role in weather patterns, erosion, and water cycles.
- The stratosphere is responsible for regulating temperature by absorbing ultraviolet radiation.
Biosphere Diversity
- The biosphere's biodiversity signifies the variety of life, encompassing plants, animals, and microorganisms.
- Organisms have adapted within the biosphere through generations, developing traits suitable for survival in diverse environments.
- The thermosphere layer of the atmosphere absorbs high-energy solar radiation, contributing to its high temperature.
