What really brings down the carbon intensity of our economies is cities using technologies such as carbon-neutral building design, carbon capture and storage, solar power generation, electric car sharing systems, and so forth.
This map identifies the cities participating in just a small number of the more than inter-city learning networks that are actively sharing best practices in every arena, from climate and safety to education and social inclusion.
This is about the same number as inter-governmental organizations. From Los Angeles and New York to London and Singapore, leading cities around the world are witnessing a growing — not shrinking — percentage of their dynamic and industrious populations coming from abroad.
No city in the world has a higher foreign-born population than Dubai, where almost all residents come from India and Pakistan as well as elsewhere in Europe and Africa.
A half-century ago there were only a handful of Special Economic Zones SEZs — designated areas with more free-market oriented economic regulations — in poor countries like Mauritius and the Dominican Republic to help boost their agriculture and textile industries. Across Asia, upstart manufacturing powerhouses like Vietnam are using the same model to rapidly climb the value chain —even stealing investment away from China.
In a Mercator projection, Greenland and Africa are about the same size. In reality, Africa is 14 times the size of Greenland. Also called a temperate zone. Sea level is determined by measurements taken over a year cycle.

A political boundary is an imaginary line separating one political unit, such as a country or state, from another. Sometimes these align with a natural geographic feature like a river to form a border or barrier between nations.
Occasionally, two countries may contest where a particular border is drawn. These disputes might arise due to a natural resource both groups want, like in the case of Sudan and South Sudan, or in an attempt to gain more political power, as in the case of Pakistan and India in the Kashmir region.
Use these resources to explore more about political boundaries. A territory is land a person or government protects from intruders or outsiders. Some territories have defined boundaries like a nation, province, or city, while others, like a neighborhood, may not. The people living in a particular territory often share similar traits, like ethnicity, culture, or religion. In some places, the exact boundary and who claims what land is questioned.
An example of this is the region of Kashmir between India and Pakistan which has been under dispute since the s. Help your students cross the boundary to understanding territorial divisions with these resources. In geography, boundaries separate different regions of Earth. A physical boundary is a naturally occurring barrier between two or more areas. Physical boundaries include oceans, cliffs, or valleys.
Select from these educational resources to teach middle school students more about physical boundaries. Whether your map is paper or digital, mastering the basics of reading it are vital to finding your way around and understanding how the world works. Maps are fantastic visual tools that can help us communicate spatial concepts and patterns, tell stories, and analyze data.
However, there are some challenges to translating Earth onto a flat surface without adding bias or inaccuracies. Fortunately, cartographers have the training to minimize these issues. Maps have been a part of the National Geographic Society since the beginning. Gilbert H. It's lines and colors show the realization of great dreams. Whether a description of a keystone species or the impact of the Pacific garbage patch, these articles provide insight into a breadth of important issues facing our world today, including the environment, civic engagement, and history.
One of the oldest tenets of geography is the concept of place. Location is the position of a particular point on the surface of the Earth.
Locale is the physical setting for relationships between people, such as the South of France or the Smoky Mountains. Finally, a sense of place is the emotions someone attaches to an area based on their experiences.
Place can be applied at any scale and does not necessarily have to be fixed in either time or space. Additionally, due to globalization, place can change over time as its physical setting and cultures are influenced by new ideas or technologies. Learn more about the physical and human characteristics of place with this curated resource collection.

A political map does not show topographic features like mountains. It focuses solely on the state and national boundaries of a place. These maps also include the locations of cities large and small, depending on the detail of the maps. A typical example of a political map would be one showing the 50 U. A physical map is one that documents landscape features of a place. These maps generally show things like mountains, rivers, and lakes.
Bodies of water are commonly shown in blue. Mountains and elevation changes are sometimes shown with different colors and shades to show elevation. On physical maps, greens usually indicate lower elevations while browns usually indicate higher elevations. This map of Hawaii is a physical map. Low elevation coastal regions are shown in dark green, while the higher elevations transition from orange to dark brown.
Rivers are shown in blue. A topographic map is similar to a physical map in that it shows different physical landscape features. Unlike physical maps, though, this type of map uses contour lines instead of colors to show changes in the landscape.
Contour lines on topographic maps are normally spaced at regular intervals to show elevation changes e. When lines are close together, it means the terrain is steep. A climate map shows information about the climate of an area. These maps can show things like the specific climatic zones of an area based on the temperature, the amount of snow an area receives, or the average number of cloudy days.
These maps normally use colors to show different climatic areas. This climate map for Australia uses colors to show differences between the temperate area of Victoria and the desert region in the center of the continent. An economic or resource map shows the specific types of economic activity or natural resources present in an area through the use of different symbols or colors depending on what is being depicted.
