Learning Objectives Students should be able to define Physical and Human Geography Students should be able to list the 7 Major Biomes Students should be able to identify the characteristics of a particular Biome
Geography Physical geography is the study of the natural features of the Earth’s surface: eg mountain ranges, deserts, oceans, forests and ecosystems. Human geography is a branch of the social sciences that studies the world, its people, communities and cultures.
Physical Geography has two main factors Abiotic (non-living) factors – temperature, wind, humidity, rainfall, soil types-salinity-pH, seasons, altitude (height above or below sea level), latitude (distance away from the equator). Biotic (living) factors – Fauna (animals), Flora (plants), Fungi and micro-organisms such as protozoa, bacteria and viruses (which are not defined as being alive)
Ecosystem An ecosystem is a local community of living organisms (plants, animals and microbes) in conjunction with the non-living components of their environment (things like air, water and mineral soil), interacting as a system. These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows.communitynon-living components Ecosystems are smaller components of the larger Biomes.
Biomes A biome is a large geographical area of distinctive plant and animal groups, which are adapted to that particular environment. The climate and geography of a region determines what type of biome can exist in that region. Major biomes include deserts, forests, grasslands, tundra, and several types of aquatic environments. Each biome consists of many ecosystems whose communities have adapted to the small differences in climate and the environment inside the biome. Eg Marine Biomes contains, reef, tidal, mid-ocean ecosystems.
