How do the worlds of human geography and physical geography overlap? Daisy Liu G9
We have two parts of Geography: Human Geography and physical geography,
Natural geography is a subject that studies the composition, structure, function, dynamic and spatial distribution law of natural geographical environment. It is an important branch of geography. Human geography is a subject to study the geographical distribution, diffusion and change of human phenomena, and the formation and development of the regional structure of human social activities. Human geography and physical geography are mutually influenced.
Human activities will cause harm to the natural environment, for example,

According to the according to historical records, from December 5th to December 8th of 4 days, the city of London, the death toll reached 4000 people. After December 9th, due to changes in the weather, fog gradually dissipated, but after two months, nearly 8000 people died because of the smog event of respiratory diseases. Because humans use a lot of coal, destroy the environment that has caused this tragedy, people not only use a lot of coal, but also not clean, so that coal polluted air bath environment. It will happen in London haze events.
Not only that, there are Losangeles photochemical smog event occurred in 1943 in the American city of

As a result of human activities, the environment is in many ways, degradation, and global warming will accelerate these degradation. (1) because of the high temperature melting glaciers, water thermal expansion, causing the sea level to rise. Sea level rise will be a serious threat to coastal areas, may inundate low-lying coastal areas, serious impact on human activities. (2) climate change caused by global warming will lead to great changes in water supply in many places, the availability of fresh water will be greatly changed. The temperature increase means down to the water will be evaporated, if there is more rainfall to supplement evaporation, is not What impact. (3) effect on agriculture and food supply. Firstly, global warming will cause the global total grain yield declined. In addition, the insect is a cold-blooded animal, affected by climate is particularly evident because of climate warming in distribution area of crop pests can be extended to the edge of the area, but also make many the survival rate of pests (4) global warming will make the forest resources have been seriously affected, first of all, the forest serious wilt. Therefore, the natural ecological system will be more and more can
The geography of empires and kingdoms such as the Phoenicians and the Persians has affected their establishment and success. Paragraph 2: In Egypt and Mesopotamia, geography is a big part of how civilizations were created. Egypt naturally has boundaries which makes it a good place for a civilization. Egypt’s boundaries include the Nile, Sahara desert, red sea, and mediterranean sea.
Chapter 1 Outline: 1. Geography a. Human geography i. Study of human activities and where and why they are located where they are. b. Physical geography i. Study of natural forces and where and why they occur c. Place and Region. i.
With this statement, Mackinder makes a claim and says that no rational political geography can function without being built upon the ideas of physical geography. He says the idea of political geography is currently based upon no principles of physical geography and must not be considered a true discipline. This defines the complex and typically unseen relationship between political and physical geography, “Geography is like a tree which early divides into two great branches, whose twigs may none the less be inextricably interwoven.” (Mackinder 159). After Mackinder makes an interesting claim about how the rivalry between physical geographers and geologists are perceived.
Population growth has continued to grow and people have continued to use up the earth’s resources. Climate change is an issue caused by humans and their disregard for the planet. Humans have used up so much of the earth’s resources that it poses a threat to all things living. Animals are becoming extinct and their habitats are being lost. Humans need to expand and build more places to live because there is not enough space for everyone due to population growth.

Harm de Blij’s Why Geography Matters: More Than Ever explains the necessity of geographic knowledge in today’s society and the need to further expand interactions within the United States and other countries. This novel expands on the economic, cultural, physical, and political geography of our nation. De Blij outlines on the importance of geographic thought by focusing on climate change, terrorism, the rise of states, and development in Africa.. I believe that while geography has proven to make a noticeable difference in the knowledge of our vast world, it will require an extensive amount of effort in order to make geography known.
Chapter 8 Review 3. The horizontal wind determines the spacing between the isobars on a surface weather map each day. For example, if the pressure gradient is strong for that specific day, the isobars would be close together resulting in high winds. If there was a low pressure gradient, the isobars would be more spread out. Thus meaning, that the horizontal winds blow from locations that have higher pressures to lower pressures.
In Prisoners of Geography, Tim Marshall argues that geography constrains and shapes all nations and their leaders. Their actions are limited by mountains, rivers, seas, and concrete. He argues that to really understand world events, one must also consider geography. Physical characteristics affect the strengths and vulnerabilities of regions. In his book, Tim Marshall examines Russia, China, the Middle East, Latin America, the United States, Africa, Western Europe, Japan and Korea, and Greenland and the Arctic.
Positivism in physical geography is applied through a number of steps: establish research problem, establishing data sources: primary and secondary sources, selecting samples: random and not-random and methods of analysis: statistical techniques. In physical geography the positivistic approach is normally applied through the scientific method, but this is not the only way in which the positivistic approach is applied. There is also an aspect of realism to the positivistic approach as geographers need to assume there is an external reality that is capable of being examined. A careful measurement should be taken as measurement often alters measured entity. Through positivism physical geographers use reductionalism, which is done by only picking a representation of variables to observe and measure.
The Earth normal temperature rose about 0.6° Celsius in the 20th century. There have been legion global warming durations in Earth history. The long effects awaited from the global warming in the 21st century include heat waves, dryness, flooding, sea levels improving, melting of glaciers and polar ice caps, hastiness and temperature irregularity and forest fires. Accordant to the National Resources Defense Council, climate changes will directly influence water supply sustainability profound the United States in future orientate.
Global warming can cause many changes in our environment. Polar ice caps can start to melt which can cause rising sea levels and can easily lead to coastal flooding on the eastern seaboard. There can also be affects on the types of storms that can occur if global warming continues. Scientists say that category three storms can turn into a more dangerous category fours. Farms and cities will face new pests, heatwaves, heavy downpours, and increased flooding.
Consequences of global warming Global warming is causing the glaciers to melt specially in rise in sea level would destroy the plants and other species as the area would get over-flooded. The animals would die from hunger due to the deterioration of forests and plants. Ultimately the people who have survived the flood and heat would suffer at the hands of hunger as the only two sources of food we have would get destroyed due to global warming.
When large storms hit land with these increased sea levels it causes large storm surges that can destroy anything in its paths. If temperatures continue to rise other natural disasters could occur ("Global Warming Will Produce More Katrina-Like Storms"). A warmer wetter atmosphere could spawn more tropical storms and there will be floods in places that do not get much rainfall. Humans could prevent these problems if they were to cut down on the use of fossil fuels and use more renewable energy. Renewable energy consists of wind, solar, and lunar power.
Climate change is the most rising issue of the modern world that is threatening our planet from the last few decades. In the simplest definition, the term climate change refers to the rising of the planet’s temperature, particularly an increase in the average atmospheric temperature. It should be noted that in the last few decades, many scientists and ecologists has discovered the Earth temperature is increasing at an alarming rate and has affected the planet in numerous of way. The constant change in the climate due to various causes is threatening the preservation of the Earth and its human life. It should be noted that the climate change is linked with several of the human activities that are further directed towards the global warming.
Global warming is the change in the average temperature of the earth is surface as a result of humans’ activity that pollutes the nature. The level of carbon dioxide has been increased in the upper part of the atmosphere which it leads to increase the average temperature on the surface which it causes many problems in many side of life including nature, health and economy. Increasing the concentration of carbon dioxide is due to release of poison gases to the atmosphere by cars, manufactures, oil field, burning of natural gases and smoking. Air pollution and climate change are a result of increasing the level of carbon dioxide around the world.
