Ecology and Environmental Conservation
Introduction
Ecology studies the interactions of organisms with each other and their physical environment. It explores how environmental factors (biotic and abiotic) influence life, regulating the number and abundance of species in specific locations and times.

Earth’s Internal Dynamics and Plate Tectonics
1. Earth’s Internal Dynamics
Earth’s internal activity stems from the vast thermal energy stored within its interior, driving convective currents.
Convection Within Earth
Convection involves updrafts and downdrafts within a fluid, occurring when the top layer becomes denser and sinks, while the less dense bottom layer rises. As hot fluid expands, its density decreases, leading to updrafts. Conversely, colder, denser fluid sinks, creating downdrafts. This process occurs in two distinct layers: the
