Human Modification of the EnvironmentFor thousands of years, humans have modified the physical environment by clearing land for agriculture or damming streams to store and divert water. As we industrialized, we built factories and power plants. While these modifications directly impact the local environment, they also impact environments farther away due to the interconnectivity of Earth’s systems. For example, when a dam is built, less water flows downstream. This impacts the communities and wildlife located downstream who might depend on that water. Use these resources to teach your students how humans modify the physical environment and the compounding impacts those changes have.

1. Relief and landforms 2. Weather and climate 3. Soil type and quality 4. Water supply 5. Vegetation 6. Raw materials/natural resources 7. Natural threats C. Human Factors1) Agriculture 2) Secondary industry 3) Accessibility 4) Political decisions 5) Conflict D. Task on factors affecting population densityCarefully read the material above; you could research online to find additional detail/factors. Use the information to create a clear, visually appealing mind-map showing the physical and human factors affecting population density. The finished mind map should take at least a full page of your book and use colour and images as well as text. E. Activities
What is urban population in geography?Definition: The percentage of total population of a country, territory, or geographic area living in places defined as urban, at a specific point of time, usually mid-year. The term urban refers essentially to cities, towns, and other densely populated areas.
What shows an urban population?C. While showing population distribution, rural population is shown by dots and circles are used to show the urban population.
What is an example of urbanization in geography?One effect of this huge increase in people living in urban areas is the rise of the megacity, which is a city that has more than 10 million inhabitants. There are now cities with even more than that. Tokyo, Japan, for example, has nearly 40 million residents. Another effect of urbanization is urban sprawl.
What is urban growth in geography?Urbanisation means an increase in the proportion of people living in urban areas compared to rural areas . The world's population is growing rapidly and reached 79 million people in 2022.
