Mastering Vermicomposting: Stages & Essential Care
Introduction to Vermicomposting
Vermicomposting is a bio-oxidative process in which earthworms convert organic waste into nutrient-rich compost known as vermicompost or worm castings. This method is eco-friendly, cost-effective, and highly efficient in recycling organic matter. It not only helps in waste management but also improves soil health, fertility, and crop yield naturally.
The process depends on the activity of decomposer organisms, mainly earthworms such as Eisenia fetida, Eudrilus eugeniae,

Plate tectonics is currently the theory that best explains the dynamics of Earth’s geological processes.
Theory of Plate Tectonics
This theory proposes the dynamics of the Earth based on several key factors:
- Ocean floor
- Lithospheric plates
- Plate boundaries
- Lithospheric dynamics
Ocean Floor Dynamics
Oceans cover 71% of the planet’s surface. Beneath the waves lies an underwater relief known as the oceanic ridge, where sediments are scarce.
Characteristics of the Oceanic Lithosphere
- Youthful Age: Oceanic lithosphere
Wastewater and Waste Management Fundamentals
Wastewater Treatment Plant (WWTP)
A Wastewater Treatment Plant (WWTP) is a facility where a set of purification and treatment systems are applied to wastewater. The goal is to enable its reuse, decontamination, and safe disposal into the environment or directly into the sea, without risks to health.
WWTP Schematic
Water Line:
- Pretreatment
- Primary Treatment
- Secondary Treatment
- Tertiary Treatment
- Disinfection
Sludge Line:
- Sludge Thickening
- Sludge Stabilization

Architectural Divisions of the Great Mosque
On either side of the wall, two distinct spaces were created:
The Sabat: Passage to the Caliph’s Palace
Turning right (west) led to a passage towards the Alcazar or the Government Palace. This Sabat function allowed the Caliph to enter the Maksura without having to go outside the complex.
The Treasury: Safeguarding Mosque Riches
Turning left (east) was intended to house the mosque’s treasure. This included money, jewelry, gold, and especially the minbar. This
Magma Differentiation and Metamorphism in Rocks
Fractional Crystallization: As magma cools, its components begin to crystallize, forming minerals. Crystals form over time but successively. As magma cools and pressure changes, different minerals crystallize at different temperatures. This process, fractional crystallization, leads to the separation of solid phases from the liquid magma. The solid phases consist of minerals that have already crystallized, while the liquid phase is formed from remaining minerals, water, and gases.
Magma Differentiation:
