Does Earth always remain the same?
Future of Our home: Earth • Earth's Moving Puzzle Pieces: Shifting Continents The movement of the Earth's continents is one of the most visible manifestations of its dynamic. The theory of plate tectonics describes how the Earth's lithosphere (the stiff outer layer) is separated into shifting tectonic plates. These movements cause earthquakes, volcanic eruptions, and the slow repositioning of landmasses over millions of years. • Volcanic Activity: Internal Planetary Fireworks Volcanic eruptions, whether on land or beneath the ocean's surface, serve as a reminder of the enormous geologic activity that exists beneath our feet. Magma from the Earth's mantle occasionally erupts, forming new land, altering landscapes, and even influencing global temperature. • Biological Evolution: The diversity of life on Earth attests to the ever-changing nature of our planet. As species struggle for resources and adapt to environmental changes, they evolve, adapt, and become extin...
