Mind Map- Geography
What is geography?
Geography is the study of the world around us. Studying geography helps us understand how the Earth works. This includes natural processes (such as volcanoes, floods and the weather) as well as human activities (such as mining, tourism and building cities).

Interconnection
Places are parts of the Earth’s surface that are identified and given meaning by people. A place can be as small as your bedroom or as large as the entire planet! Places can be natural (that is, shaped by the environment and largely unchanged by humans) or built (that is, constructed by humans).
To most people space means the empty universe but to a geographer, it has a different meaning. Geographers investigate the way that things are mapped and arranged on the Earth’s surface. The concept of space has three main elements.
The world in which we live is made up of many different environments. Some environments are natural (or physical) such as deserts, grasslands, mountains, coral reefs, forests, oceans, and ice caps. In order for an environment to be considered natural, its soils, rocks, climate, plants, and animals must remain largely untouched by humans. Today, there are very few truly natural environments left on Earth.
Location
Spatial distribution
Organisation
How and why things are arranged and managed on the Earth’s surface by people.
Where things are located on the Earth’s surface.
The shapes and patterns in which things are arranged on the Earth’s surface.
Geographers use the concept of interconnection to better understand the complex links between natural and human processes that shape our Earth. Places and people can be linked in many different ways that can be categorised as:
Natural processes
Human activities
Such as the water cycle and the food chain.
Such as the movement of people, the production and trade of goods and the flow of investment and money within and between different countries.
The concept of sustainability relates to the ongoing capacity of Earth to maintain all life. This means developing ways to ensure that all resources on Earth are used and managed responsibly so they are there for future generations.
Scale is an additional concept used to guide geographical inquiries. Geographers study things that take place on many different spatial levels – meaning from small areas (such as a local park) to very large areas (such as the use of oil and coal all over the world).
The concept of change is important in geography because it helps us to understand what is happening around us. Changes can be caused by natural processess, such as climate or natural disasters, or by human processes.
Geographical skills
Geography has been described as the ‘why of where’. Geographers examine the world and try to explain what they see. Like a detective at the scene of a crime they follow a line of inquiry. To follow a line of inquiry, geographers need a range of skills. They are:
Analysing
Evaluating
Questioning and researching
Communicating and reflecting
Geographers ask lots of questions. Geographical questions can be as simple as ‘What is it?’ and ‘Where is it?’ or more complex, such as ‘What is the connection between these two things?’ and ‘How and why have things changed over time?’.
Once you have collected and recorded your data, it is time to identify any trends, patterns or relationships in the information. You will have used questionnaires and surveys to gather visitor statistics, drawn sketches and diagrams, created graphs and tables and taken photographs (all of which are primary data).
The next stage of a geographical inquiry is to evaluate what you have learnt in order to draw a conclusion. There are a number of methods to evaluate your evidence.

Sources
Collect information themselves by interviewing people, taking photographs, making sketches out in the field or conducting surveys and questionnaires. This kind of information will generally only be relevant to a particular inquiry and is called primary data.
Often a geographer collects information that supports his or her inquiry but has not been specifically collected or designed by the geographer for the inquiry. This type of information is called secondary data.
Pattern
Exceptions
A pattern may be a group of similar features on a diagram, a concentration of a particular colour or feature on a map, or a particular shape that is created by data on a column graph.
Often you may find that there are things in your data that do not fit into a pattern you have identified. These are called exceptions. They also need to be identified and quantified. For example, you might say ‘There are a number of other mountain ranges that are not on the east coast.
Quanitify
Quantifying involves using statistics, amounts, sizes and locations to give specific details. For example, rather than just saying ‘Most mountains run along the coast in the east’, you would need to quantify this statement.
Graphs
Graphs are one of the most effective graphical representations when it comes to showing numerical (or quantitative) data. Some kinds of graphs are simple, while others are more complex.
Line graphs
Line graphs show information as a series of points that are joined up to form a line. The line shows a trend or change over time. The horizontal axis (x) will usually show units of time and the vertical axis (y) will usually show amounts.
Column graphs
Column graphs are similar to bar graphs, but they show information as a series of vertical columns that are arranged side by side. They are also usually used to compare quantities.
Bar graphs
Bar graphs show information as a series of bars that run in a horizontal direction and are stacked one on top of the other. They are usually used to compare quantities.
Column
Pie graphs
Pie graphs are circular in shape and are divided up so that the information being shown represents the slices of a pie. The circle of 360 degrees represents 100 per cent and each of the slices is a percentage of that.

Maps
Geographers use different types of maps to show a whole range of different natural and built features – and the connections between them. These maps include:
Physical maps
Physical maps show the locations and names of natural features of the Earth. These may include deserts, mountains, rivers, plains, oceans, reefs, volcanoes and lakes.
Political maps
Dot distribution maps
Flow maps
Overlay maps
Choropleth maps
Topographic maps
Weather maps
Thematic maps
Political maps show the locations and names of built features of the Earth. These may include country borders, state and territory borders, cities and towns.
Dot distribution maps use dots (or shapes) to represent (and sometimes compare) a range of different features. The dots show the location of the chosen feature. The size and colour of the dots on the map can show different characteristics of that feature.
Flow maps show movement from one place to another. Arrows of different thicknesses or colours are used to show where different things (such as people or goods) are moving to and from, and to compare the numbers involved in the movement.
Overlay maps show how features on the Earth’s surface may be related to each other. To create an overlay map you fi rst need to produce a base map showing one feature (such as the location of Australian rainforests) and then place a piece of tracing paper or plastic sheet over this base map showing the other feature you are investigating (such as areas with a moist tropical climate).
Choropleth maps use different shades of the same colour to give a quick impression of the pattern formed by the data being shown. Darker shades show the highest values or the greatest amounts, while lighter shades show the lowest values or the least amounts.
Weather maps show conditions in the atmosphere, such as air pressure, wind speed and wind direction. They also show the size and location of warm and cold fronts.
Topographic maps show the shape of the land (such as the shapes formed by valleys, hills and ridges) by using contour lines. Numbers on some of the contour lines show the height of the land above sea level.
Thematic maps show a particular theme or topic; for example, the distribution of resources (such as coal and gas), the different types of forests around the world, access to safe drinking water, or the types of crops and animals farmed in Australia.
BOLTS
Border
An outline or box drawn around the map.
Orientation
Legend
Title
Scale
Source
An indication of direction, usually shown with a north arrow or compass rose.
An explanation of the symbols, colours and patterns used on the map (also known as a key).
A heading that describes the map and what it is showing.
A way of indicating what distances on the map represent in the real world.
Where the information used to create the map came from. If these details are not known, simply write ‘Source: unknown’.
Landscapes and disasters
Landscapes
A landscape is part of the Earth’s surface. It consists of a variety of geographical features that are characteristic of an area. Landscapes are divided into two main categories – natural and human.
Landforms
A landform is a natural geographic feature or shape that appears on the Earth’s surface. Large landforms include mountains, plains, and rivers while small landforms include hills and billabongs.
Disasters
A disaster is a tragic circumstance that creates damage to wildlife and buildings. Some disasters last for a short amount of time but some don’t. Usually, the duration doesn’t affect the loss of lives in these deadly situations. The two main types of disasters are man-made and natural.
