The distribution of the earth’s population across the globe is uneven. The earth contains many different environments with only few parts suitable for human habitation.
Around 70% of the earth’s surface is covered in water, leaving only 30% as land; however within this portion exist many physical features...
has three main branches: Physical human and regional. Physical geography is further subdivided into several other branches namely; Geomorphology, Climatology, Oceanography, soil and biogeography. Human Geography is also subdivided into other branches like, cultural, population, social, economic and political...
Branches of Geography
There are two main branches of geography viz., physical geography and human geography. All the other known branches of geography, essentially are the sub-branches of these two.
Physical geography, a.k.a. physiography is a natural science that deals with patterns...
Population distribution is how people are dispersed over a given area. Population distribution is measured by persons per square kilometer. An area (or country) can be densely populated, which means there is a high concentration of persons per square kilometer, or sparsely populated, which means there...
Ecology is the scientific study of the interactions between organisms and the environment. Ecologists are determined to explain both the distribution of organisms and their abundance. In addition to its long history as a descriptive science ecology is also a rigorous experimental science. Ecologists...
planet, and water is an absolute requirement of life. On our planet, the most controlling resource is water — not oil or minerals — but water. Its distribution, quantity, availability, and quality are the controls for the development of agriculture, industry, rural, urban, and municipal use. The water-rich...
controlled by climatic factors, habitats by local irregularities of topography. Therefore, distribution of organisms is also determined by these factors.
III. The physical environment controls and otherwise influences the development of the biological community and its population dynamics.
improves the nation’s security and creates jobs for Australians
Future Challenges – Population:
* Density of Australia is low, about 2 people for every km2
* Growth rate is 1.9%
* Factors affecting population growth rate include
* Fertility rate- number of children born
A Local Ecosystem
1. The distribution, diversity and numbers of plants and animals found in ecosystems are determined by biotic and abiotic factors
a) Compare the abiotic characteristics of aquatic and terrestrial environments
- An ecosystem includes...
order to begin this investigation, we determined that the
factors that were to be tested as independent variables were weight, height, and amount of
regular physical activity. We decided that eating breakfast in the morning does not affect
the amount of calories needed during lunch, according to a...
Poverty and income distribution in Asian countries
Almost half of the world, that is, three billion people lives on less than $2.50 a day and at least half of the humanity lives in countries where income disparities are present.[Anup Shah, Poverty facts and stats] If we perceive things in a materialistic...

So, what is nutrition? A definition of nutrition is provided and an examination of the factors which influence healthy...
tropics, but in general the distribution of these storms is controlled by the places where sea temperatures rise above 27˚c and is heated to a sufficient depth. The impacts of tropical revolving storms can be devastating. While hazardous events cannot be prevented, human actions before and after can...
Poverty in India
Poverty is one of the major problems in India. It is the root cause of many socio-economic problems including population explosion, unemployment, and child labour and rising graph of crimes. Poverty alleviation should be the main target of the nation so as to make it...

* For example, hawks feeding on field mice kill certain individuals (over ecological time), reducing population size (an ecological effect), altering the gene pool (an evolutionary effect), and selecting for mice with fur color that camouflages them in their...

Some say that the pattern of human settlement in Southeast Asia is dispersed settlements where buildings are spread out; an example would be the rural areas of Philippines, where different...
This essay is about the Population Distribution in south east and north Brazil. It describes how uneven populated the different areas of
Brazil are. It includes explanations and reasons in human, physical, economic and social context. Brazil in terms of population distribution is extremely varied and...

Question : Examine how one’s health conditions are determined by social factors such as gender roles and economic positions. What would you suggest to tackle the issue of health inequality?
environmental biology both stem from Darwin’s interest and observations upon the distribution of organisms and how they adapted to their specific environment. Darwin concluded that the environment interacting with populations could cause evolutionary change. We now know that small changes in the ecological...

To satisfy ones hunger, they may opt to eat either rice or noodles depending on their preference. Demand, the human wants that are backed by buying power indicates a person’s financial...

the distribution and abundance of organisms
A. Ecologists use observations and manipulative experiments to test hypotheses
B. Sophisticated computer programs develop models that predict the effects that human activities will have on a climate and how the resulting climatic changes will affect geographic...
Distinguish among organismal ecology, population ecology, community ecology, ecosystem ecology, and landscape ecology.
5. Clarify the difference between ecology and environmentalism.
Interactions between Organisms and the Environment Limit the Distribution of Species
6. Define biogeography.
Assess the contribution of human and physical factors to the global distribution of biodiversity (15)
Biodiversity refers to the number of species, ecosystem and genes in a given area or the planet.
Extinction of different kinds of biodiversity is a natural even that has occurred for several millions...

The ocean sustains life on this planet. It impacts all humankind in this global society. It dramatically affects climate systems and makes the earth a hospitable place to live. Coupled to the atmosphere, it continually recycles air and water, purifying them in...
Biodiversity, Species Interactions, and Population Control
1. Two major factors affect the number of species in a community: the latitude in terrestrial communities and salinity/nutrients in aquatic systems.
2. Species play different roles in a community. Native species...
