What is Geography?

It’s important to study where we live in, and that’s earth.

Geography deals with the scientific study of earth’s surface, our ecosystems and the different environments including the relationship between man and his environment.

Geography helps us to better understand earth and our diverse environment.

Please read on the concept of an ecosystem here.

Branches of Geography

Geography is divided into 3 main branches or types. These are:

  1. Human Geography
  2. Physical Geography
  3. Environmental Geography
  4. Please read on physical and environmental geography here.

 

Human Geography

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.
    Please read on the definition and scope of commerce here.


  • 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.
    Please read on the early years of Jesus here.


  • Medical Geography: It studies the process 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 'ebola'. (Ebola is a case study here).
    You can read on micro-organisms causing food, water and air borne diseases here.


  • Settlement Geography: It deals with the study of the urban and rural settlements, their evolution; including the way and manner with which they are distributed.

  • Social Geography: This branch of human geography deals with the study of the human society.

    Social Geography is divided into Political geography and Population geography.
    Please read on social studies and it's objectives here.


  • Political Geography: This branch of social geography deals with the study of political units, nations and how they are bordered; including the behaviors within such nation’s geographical setting.
    Please read on democracy and types of democracy here.

  • Population Geography: This branch of social geography deals with the study of human demographics and distribution.

    Human race, origin, composition, mortality, fertility, population and migration are all covered under population geography.


Other branches of human Geography include:

  • Urban Geography
  • Historical Geography
  • Transportation Geography
  • Industrial Geography
  • Agricultural | Land use Geography
  • Behavioral Geography
  • Regional development and planning

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

1. Igneous Rock

Igneous Rock - Len Academy

 

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.
