Understanding Environmental Systems: A Holistic Approach
Understanding Environmental Systems
A Holistic Approach to Environmental Studies
The environment encompasses all physical, chemical, biological, and social components that can directly or indirectly affect life and human activities. Environmental studies require an interdisciplinary approach, drawing from fields like ecology, economics, sociology, law, biology, geology, physics, chemistry, mathematics, engineering, architecture, and medicine. A holistic vision is crucial to understanding the complex

Rocks
Igneous Rocks
Igneous rocks are formed when magma or lava cools and solidifies. They can be classified into two main types: intrusive and extrusive.
Intrusive Igneous Rocks
Intrusive igneous rocks are formed when magma cools and solidifies slowly beneath the Earth’s surface. They are typically coarse-grained and have a crystalline texture.
Granite
Granite is a common intrusive igneous rock. It is composed of quartz, feldspar, and mica. Granite is a hard and durable rock that is often used for building

Mineral Properties
Habit (Crystal Morphology)
Minerals exhibit various crystal habits based on their internal structure and growth conditions. Some common habits include:
- Acicular: Needle-like crystals.
- Arborescent: Branching, tree-like formations.
- Bladed: Flat, elongated crystals resembling blades.
- Botryoidal: Rounded, grape-like clusters.
- Columnar: Elongated crystals resembling columns.
- Cubic: Cube-shaped crystals.
- Dendritic: Branching, plant-like formations.
- Drusy: A surface covered with small crystals.
Soil Formation and Degradation
Soil Formation
Soil is a dynamic natural body with its own origin and development, sustaining biomass and determining vegetation. Soil Science defines it as “an organized and independent natural body, with constituents, properties, and genesis resulting from the actions of active factors (climate, organisms, topography, and weather) on parent material (bedrock).”
Parent Material
Soil originates from parent material found on the Earth’s surface. This material can be existing rock, but more often, it

Solar Radiation and Atmospheric Interaction
Stefan-Boltzmann Law and Planck’s Law
Solar radiation interacts with the atmosphere according to the Stefan-Boltzmann Law (R = σ · T4) and Planck’s Law (E = h · v). These laws explain how energy is emitted and absorbed by objects at different temperatures and frequencies.
Solar Spectrum and Earth’s Energy Balance
The solar spectrum consists of various wavelengths, including X-rays, gamma rays, ultraviolet (UV), visible light, and infrared radiation. Earth’

Science and the Scientific Method
Science is a body of knowledge obtained through the application of the scientific method. It arises when a mythical view abandons reality and focuses on an objective and reflexive vision.
Modern science, or the current conception, dates back to the 16th-17th centuries, initiated by Galileo (1564-1642) and completed by Newton (1642-1727). It is based on the application of the scientific method.
