Earth’s Geochemical and Dynamic Units: A Comprehensive Analysis
Geochemical Units
Geochemical units are defined by the composition of the chemical materials that make them up.
Crust
The crust is the outermost layer of the Earth, extending from the surface to the Mohorovičić discontinuity. There are major differences in thickness and composition between continental and oceanic crust.
1) Continental Crust
The continental crust ranges from 25 to 70 km in thickness. It is very heterogeneous, consisting of dense quartz rocks, feldspars, and micas. The lower half is

Waste Incineration
48. How do normal waste incinerators operate? They operate at 1,100 °C with a gas retention time of 2 seconds to achieve 99.99% destruction of incinerated waste. The calorific value of the waste stream is used as fuel while achieving the total destruction of the material.
Rubber Recycling Challenges
49. Owing to the chemical reactions that irreversibly set the rubber during processing, the biggest problem worldwide is that rubber cannot be recycled and is not biodegradable. Because

Alternative Energy
A. From the Sun (Renewable):
The big problem is that solar energy is widely dispersed and needs to be concentrated.
Architectural Systems Liabilities:
It’s possible to heat or cool a house using only sunlight. Planting trees near buildings can reduce air conditioning needs by 60%. Trees act as biological solar collectors, passively cooling buildings by providing shade and evaporating water, which cools the environment.
Solar Power Plants:
These are facilities where energy is obtained
Understanding the Formation of Earth and Its Layers
Theory of Planetesimals
Initial Nebula
The rotating nebula of dust and gas began to contract.
Gravitational Collapse
The contraction or collapse formed a central mass of gravity and a disk around it.
Formation of Protosun
The collision of particles in the central mass released a large amount of energy.
Planetesimal Formation
The process followed gravitational attraction, causing particles around the sun to collide and group together to form larger planetesimals.
Formation of the Earth
Accretion of Planetesimals
As

Dynamic Oceanica
Marine Currents: redistribute the heat received from the Sun, accounting for differences in solar radiation by latitude. They are crucial heat delivery mechanisms for the Earth. Surface ocean currents (eddies are produced in the oceans as cyclonic or anticyclonic formations). Deep sea currents (occur due to differences in water density).
Tides: Deformations of sea level are caused by the gravitational attraction exerted on the Earth by the Moon, and to a lesser extent, the Sun.
Spanish Plateau: External Ridges, Troughs, and Coastal Relief
External Ridges and Troughs of the Spanish Plateau
The Pyrenees occupy the isthmus peninsula from the Bay of Biscay to Cape Creus. It stretches over 435 km and forms a compact and rugged mountain barrier. The Pyrenees are an Alpine range model for its structure and its geological landforms. Inside, two zones are distinguished: the axial Pyrenees and the pre-Pyrenees.
Ebro Basin
The Ebro Basin comprises the lowlands located in northeastern Spain. Its origin and geomorphological evolution are associated
