Environmenral Geography:

Environmental geography, also referred to as integrative geography, integrated geography or human-environment geography is considered as one of the branches (or divisions) of geography. The others are human geography and physical geography respectively.

Please read on human geography here.

Environmental geography covers the relationship and interactions between humans and their immediate natural environment, including the outcomes of this relationship. This environmental interaction with humans is termed 'coupled human–environment system'. In simple terms, environmental geography focuses on the interactions between humans, their environment and the earth at large.

Please read on ecological concepts here.


The practical relationship between humans and their environment was much more encountered in the past when compared to this present age. This becomes a fact because technology which happens to be the core of our modern world has taken over the environment. As an instance, you can interact with certain regions of the world without your physical presence, all thanks to technology. Meanwhile, understand that environmental geography is ideally measured through the activities of humans on natural landforms and cycles.

You can read on the internet of things here.


Environmental geography as a course of study helps us to further understand how the various human activities on an area can consequently affect such area. In addition, environmental geography encompasses the causes and spread of diseases that had resulted from environmental activities. Instances of these diseases will include the pandemic COVID-19 and regional ebola.

Please read more on diseases and vectors of diseases here.


Environmental geography has helped us to better understand how certain human activities can negatively impact the human environment. Further more, the study of environmental geography has facilitated the human-environment relationships, which explains how humans have been dependable on their surrounding natural resources in order to develop their standard of living.

You can read on the atmosphere and its functions here.


Apparently, the human environment is changing at a rapid pace as a result of technological advancement and human development. Based on this fact, it is mandatory that we learn how to use sustainable development and techniques to conserve the use of natural resources. Through this knowledge gained from environmental geography, we can therefore comprehend and fix the followings:

  1. How climate change is adversely affecting the wellbeing of humans.

  2. How humans, plants and animals are adapting to the changes in our environment.

  3. How soil degradation results into erosion and leaching.
    Please read on soil erosion here.


In summary, the study of environmental geography provides knowledge towards understanding both the physical and human environment. In fact, it is considered a part of (or a borderline between) physical and human geography. This is expressed in the image below:

Branches of Environmental Geography

In our world today, environmental geography may be considered under the following areas or branches. These are:


  1. Environmental Perception: This study involves the perception and comprehension of humans toward their environment. With this understanding, better decisions will be taken by humans towards preserving their natural environment.

  2. Political Ecology: This branch of environmental geography incorporates various systems which can be political, cultural, social or economic into various environmental changes. A proper implementation of these aforementioned systems into the human environment will significantly improve our standard of living.
    Please read on the concept of government here.

  3. Hazards: Examples of hazards studied in environmental geography include earthquakes, tsunamis, volcanoes, forest fires, drought, tornadoes and hurricanes.

  4. Energy and Resource Geography: This will include the study and implementation of energy generation through wind, water and sunlight respectively.

  5. Landscape Studies: Landscape in this regard refers to an entire area comprehended by one's vision in a single view. Landscape studies therefore involves the interactions between humans and the environment in specific areas.

NOTABLE POINTS IN Geography

The atmosphere consists of gases that surround the entire surface of the spherical shaped earth. The compositions of these gases are as follows:

Composition of the Atmosphere -Len Academy

  • Nitrogen (N2): 78.09%
  • Oxygen (O2): 20.95%
  • Argon (Ar): 0.93%
  • Carbon(IV)oxide (CO2): 0.036%
  • Neon (Ne): 0.002%
  • Krypto (Kr): 0.001%
  • Helium (He): 0.0005%
  • Xenon (Xe): 0.00009%
  • Hydrogen (H2): 0.00005%
  • Water Vapour: Variable

All of these gases (listed above) make up the atmosphere and are generally called air.

Human Geography focuses on the study of human beings, their origin, race, and how they are affected by the earth.

Human geography can be divided into the following branches:

  • Economic Geography: This aspect of human geography looks into the distribution of goods and services. Distribution of wealth across the globe is also considered here.

    Instances of economic geography include a study or research done on the richest nations on earth. During thus research, the processes accounting for their wealth are ascertained.


  • Religious Geography: It studies the origin and spread of religious groups including their beliefs.

    Instances of religious geography include the study of the Christian or Islamic religion as seen in documentaries.


  • Medical Geography: It studies the processes and events that bring about diseases and epidemics with regards to their geographical location, origin and distribution.

    As an instance, you may have heard about the geographical study and distribution of the disease 'COVID-19'. (Coronavirus is a case study here).

We have 3 main types or classes of rock based on how they are formed. These are:

1. Igneous Rock

2. Sedimentary Rock

Sedimentary Rock - Len Academy

 

3. Metamorphic Rock

Metamorphic Rock - Len Academy

Igneous rocks are formed when molten substances below the earth surface cools down and solidifies. These molten substances are called magma or lava. Magma can be derived from melting of existing rocks on the earth crust.

The solidification of molten magma into igneous rock may be below the earth's surface (intrusive) or on the earth's surface (extrusive), giving rise to the two types of igneous rock.

  • Intrusive Igneous Rock: These are igneous rocks that crystallizes below the earth’s surface. They generally cool slowly during the process of solidification and tend to produce large crystals.

    Intrusive Igneous Rocks are also referred to as plutonic igneous rocks. Examples are gabbro, granite and pegmatite.

  • Extrusive Igneous Rock: They are igneous rocks that form when molten magma erupts on top of the earth's surface. They cool down and solidify quickly, producing small crystals in the process. Sometimes, the molten magma cools so quickly, allowing no time for crystals to grow. This rapid cooling results in the formation of an amorphous glass.

    Extrusive Igneous Rocks are also referred to as volcanic igneous rocks. Examples are basalt, rhyolite and scoria.

Sedimentary rocks amount to about 76% of the earth's surface. They can be formed in different ways. These are:

  • By the deposition of the weathered remains of pre-existing rocks and their subsequent transportation and deposition. Sedimentary rocks formed in this way are known as clastic sedimentary rock.

  • By the accumulation and lithification of sediment or detrital rock.

  • By their precipitation from solution. Sedimentary rocks formed in this way are known as chemical sedimentary rock.

  • As a result of biogenic activities. Sedimentary rocks formed in this way are known as organic sedimentary rock.
