The two major branches of geography are physical geography, which focuses on natural phenomena like landforms and climate, and human geography, which explores human populations, cultures, and activities in relation to the environment.
ENVIRONMENT - the natural world, or any physical setting
Natural selection does not result in populations achieving perfect adaptation to their environment because the environment is constantly changing, which means that what is considered advantageous in one situation may not be advantageous in another. Additionally, genetic variation within a population means that not all individuals will have the same traits that are best suited for a particular environment.
Natural selection and it's ability to engender adaptive change in populations of organisms.
Geography
There are a few natural resources that is important to the Europe's. The natural resources are physical geography, environment and humans.
The natural environment is organized into various ecological levels, starting from individual organisms to populations, communities, ecosystems, and ultimately the biosphere. At each level, interactions occur among organisms and between organisms and their physical surroundings. These interactions shape biodiversity, nutrient cycles, and energy flow, contributing to the overall health and stability of the environment. Additionally, natural environments are influenced by abiotic factors such as climate, soil, and water, which further organizes ecosystems and habitats.
Physical environment refers to the natural surroundings of an area, including landforms, climate, and natural resources. Cultural environment, on the other hand, refers to the social and cultural factors that shape a community, such as language, religion, customs, and traditions. While physical environment is more tangible and can directly impact human activities, cultural environment influences social interactions and behaviors.
A physical geographer studies the processes and patterns that occur in the natural environment. Physical geography is one of the major branches of Geography.
The growth or shrinkage of populations has nothing to do with natural selection, but with the availability of resources, and the ability of organisms to utilize those resources. This is also known as 'carrying capacity'. The natural tendency is for organisms to produce more offspring than the environment can support. So if the environment supports more individuals, then the population will automatically grow. If conditions change and the environment supports less individuals, then some individuals will starve or be otherwise unable to reproduce. Natural selection, in this case, "determines" which individuals pass, and which do not.
