Biomes: Earth’s Diverse Habitats
Biomes are distinct regions of Earth, each characterized by a unique set of plant and animal communities. These communities share a common structure, function, and development pattern, all directly influenced by the prevailing climate. Biomes are broadly categorized into two main types: terrestrial and aquatic.
1. Terrestrial Biomes
Terrestrial biomes are land-based ecosystems. Within these biomes, vertical and horizontal zones can exist, depending on factors like altitude

Materials Science
Introduction
Everything in the universe consists of matter, which occupies space and has mass. This matter presents itself in nature in various forms, each with specific properties. Matter is composed of atoms. The origin of these atoms can be traced back to the Big Bang (Hydrogen, Helium, and Lithium), the cores of stars (Iron), and supernova explosions (heavier atoms).
Classification of Materials
- Raw Materials: Obtained directly from nature (e.g., wood, granite).
- Processed Materials:
