Exploring Earth’s Systems: A Comprehensive Guide
The Earth System
What is a System?
A system is a group of parts that work together as a whole.
What is Energy?
Energy is the force or capacity to do something.
Main Parts of the Earth System
The Earth system consists of four main parts:
- Hydrosphere (water): This includes oceans, rivers, lakes, glaciers, and underground water. It covers about 3/4 of the Earth’s surface.
- Biosphere (life): This encompasses all living organisms on Earth.
- Atmosphere (air): The outer layer of gases surrounding the Earth, primarily
Electricity Generation in Andalusia: A Comprehensive Overview
Electricity Generation in Andalusia
Since July 2007, the European Union has liberalized the generation and distribution of electricity. In Spain, this process began in 2003 with the Hispano-Portuguese agreement known as MIBEL (Mercado Ibérico de Electricidad).
Current Energy Mix in Spain
Currently, 73% of Spain’s electricity comes from non-renewable sources, while 27% is generated from renewable energies. The breakdown is as follows:
- Carbon: 29.1%
- Renewable Energies (including hydro): 27%
- Nuclear: 21.
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
