A square is defined as a quadrilateral with four equal sides and four right angles. This unique set of properties clearly distinguishes it from triangles or circles.

Photosynthesis is the process by which plants convert sunlight into chemical energy, producing oxygen as a byproduct. This process is essential for life on Earth.

Evaporation is the process in which a liquid turns into vapor, usually under the influence of heat. This is a key part of the water cycle.

The Continental Drift theory posits that continents slowly move across the Earth's surface over long periods of time. This theory laid the groundwork for the modern understanding of plate tectonics.

A pendulum is an example of simple harmonic motion as it swings back and forth in a regular, periodic manner. This oscillatory behavior is a common topic in introductory physics.

Mitosis is the cell division mechanism where a single cell splits into two identical daughter cells, ensuring genetic consistency. It is fundamental to growth and repair in organisms.

An ecosystem is a complex network where living organisms interact with each other and their physical environment. This concept is central to understanding ecological relationships.

A fraction represents a part of a whole and is written as one number over another, with the top number as the numerator and the bottom number as the denominator. This concept is crucial in number theory and arithmetic.

Adaptation involves changes in an organism that enhance its ability to survive in its environment. It is a fundamental mechanism in evolution and natural selection.

A lever is a simple machine that consists of a rigid bar pivoting around a fulcrum to move a load. This principle is commonly applied in many everyday tools.

Condensation is the process in which water vapor in the air cools and transforms back into liquid water. It is a critical step in the formation of clouds and precipitation.

Symbiosis refers to a close and often long-term interaction between different species, which can be beneficial, neutral, or sometimes harmful. This relationship is key to many ecological systems.

A ratio compares two quantities by showing the relative size of one quantity to another through division. It is a fundamental concept in mathematics used in various real-life applications.

Renewable resources are those that can naturally replenish and sustain over time. This characteristic differentiates them from finite resources which can be depleted.

Force is defined in physics as a push or pull that can change an object's state of motion. It is a central concept in understanding how objects interact and move.

Gravity acts between objects that possess mass, and the force increases as the mass of the objects increases. This fundamental principle is central to understanding gravitational interactions in physics.

Atoms are composed of three main subatomic particles: protons, neutrons, and electrons. This basic structure forms the foundation of chemical elements and matter.

Metamorphism refers to the process where existing rocks are transformed by heat and pressure without melting. This process changes the mineral composition and texture of the rock, leading to metamorphic rock formation.

A circuit is defined as a closed loop that allows electrical current to flow continuously. This basic concept is fundamental in the study and application of electrical engineering.

A symposium is a formal conference or meeting where experts gather to discuss a specific topic. This format encourages intellectual exchange and deep discussion on academic subjects.
