Sedimentary Basins: Formation and Processes
What is a Sedimentary Basin?
A sedimentary basin is a depression in the Earth’s relief, often bounded by mountains of varying sizes. At its bottom, vast quantities of sediment (such as gravel, sand, and mud) accumulate. These sediments are transported by rivers flowing into oceans or lakes, or by winds carrying dust from continents, which then settle on the basin floor.

The Origin of Life: Hypotheses and Theories
Alien Hypothesis
This hypothesis suggests that life emerged in outer space, then colonized our planet. It proposes that life came to Earth in the form of spores brought by meteorites. While the existence of a vast arsenal of organic compounds in space has been confirmed, there is no evidence yet of life outside Earth.
Terrestrial Hypothesis
This theory states that life began under specific prebiotic conditions, from chemical elements and physical conditions,

Air Conditioning System Basics
The primary goal of an air conditioning system is to reduce and control the temperature, humidity, and purity of the air within a vehicle’s cabin. The ideal cabin temperature ranges from 21°C to 24°C, with relative humidity between 40% and 70%. The systems commonly used are of the ‘continuous cycle’ type.
These systems aim to achieve and maintain a comfortable interior temperature quickly and consistently. They offer a range of temperature selections to ensure comfort

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,
