What Are Physical Features?
Physical features refer to the natural characteristics of the Earth's surface, including mountains, valleys, plains, rivers, lakes, and oceans. These features are formed through various geological processes and have distinct attributes that set them apart from one another.
Mountains, for example, are elevated landforms that rise prominently above their surroundings. They are usually created by tectonic forces or volcanic activity. Valleys are low areas between hills or mountains, often formed by river erosion. Plains are vast stretches of flat land with minimal elevation difference, typically formed by sediment deposition over time.
Rivers are flowing bodies of water that move from higher to lower ground, playing a crucial role in shaping landscapes and supporting ecosystems. Lakes are sizable bodies of water surrounded by land, formed by glacial, tectonic, or volcanic activities. Oceans are the largest bodies of water, covering nearly 71% of the Earth's surface and serving as significant climate regulators.
How Do Physical Features Affect Biodiversity?
Physical features significantly impact biodiversity by providing diverse habitats that support a wide range of species. Mountains, for instance, create vertical zonation, resulting in different climates and vegetation types at various altitudes. This leads to rich biodiversity, with unique species adapted to specific altitudinal zones.
Rivers and lakes serve as critical aquatic habitats, supporting freshwater species and acting as migration routes for fish and other wildlife. Wetlands, formed by river or lake overflow, are among the most productive ecosystems, offering breeding grounds for birds and nursery areas for fish.
Oceans, with their vast expanse and depth, harbor a multitude of marine species, from plankton to whales. Coral reefs, often referred to as the "rainforests of the sea," are biodiversity hotspots, providing shelter and food for numerous marine organisms.
