Study Notes
Country Shape and Measurement
- Fragmented shape: A country divided by water, land, or other countries.
- Elongated shape: A country geographically long and narrow.
- Perforated shape: A country completely surrounds another country.
- Protrude shape: One portion of a country is more elongated than the rest.
- Indices of compactness measure the deviation of a country's shape from a circle.
- Area-Boundary ratio: Measures the ratio of a country's area to its boundary length. A higher ratio indicates greater compactness.
- Boundary-Circumference ratio: Measures how closely a country's boundary approximates the circumference of a circle with the same size. A closer ratio indicates greater compactness.
- Area-Circumference ratio: Compares a country's area with the circumference of a circle passing through its extreme points. A higher ratio indicates greater compactness.
- AreaArea (A/A’) ratio: Measures the area of the smallest possible inscribing circle passing through the country's extreme points. A closer ratio indicates greater compactness.
Basic Skills of Map Reading
- Maps are two-dimensional scaled representations of Earth’s surface.
- Maps display and analyze spatial distributions, patterns, and relations.
- Natural features include mountains, plateaus, hills, valleys, rivers, oceans, and rocks.
- Manmade features include roads, railways, buildings, and dams.
Importance of Maps
- Maps provide a basis for geographical information, like relief, drainage, and settlements.
- Maps are powerful tools for spatial analysis of geographical facts.
- Maps are useful for locating geographical features through grid references and place naming.
- Maps are used in various disciplines, including land use planning, military science, aviation, tourism, marine science, population studies, epidemiology, geology, economics, history, archaeology, and agriculture.
- Maps store geographical data of the represented areas.
- Maps can potentially be used to assess reliable measurements of geographical features.
Types of Maps
- Topographical Maps: Depict natural and cultural features of an area. Can be small, medium, or large scale. Their contents depend on the purpose, scale, compilation date, and land nature.
- Special Purpose/Statistical Maps: Show distribution of various aspects, like temperature, rainfall, settlement, and vegetation.
Marginal Information on Maps
- Title: The heading of the map that indicates the area's significance.
- Key: A list of all conventional symbols and signs on the map.
- Scale: The radio between the map distance and the actual ground distance.
- North Arrow: Indicates the north direction of the mapped area.
- Margin: The frame of the map, showing its end.
- Date of Compilation: The date the map was published, indicating if it's updated or outdated.
Basic Principles of Map Reading
- Map-readers must understand the symbols and the real world.
- Each map symbol should be visualized for effective reading.
- Symbols should refer to landscape features that readers already have images of.
- Knowledge of directions is crucial for effective map use.
- Readers should determine the north direction (north arrow) before locating features.
- Readers should learn to read the direction on a specific map and the location of features in relation to each other.
- Maps use a grid system, with numbers accompanying lines, for accurate location pinpointing.
- The grid system provides an accurate description of location, known as a grid reference.
Meaning of Geography
- Geography is the scientific study of Earth.
- Geography describes and analyzes spatial and temporal variations of physical, biological, and human phenomena and their relationships over the Earth's surface.
The Scope, Approaches, and Themes of Geography
- Geography explains natural and cultural features on Earth's surface.
- Geography contributes to understanding the changing spatial structures from the past to the future.
- Scope: The Earth’s surface and the interface between the atmosphere, lithosphere, hydrosphere, and biosphere.
- Approach: Human-physical continuum and topical regional continuum.
- Topical fields: View physical or human phenomena as distributed over Earth.
- Regional geography: Focuses on the associations within regions of elements and their interrelationships.
- Five basic themes: location, place, human-environment interaction, movement, and region.
Geographic Concepts
- Location: A specific place or position. Types: Absolute location (defined by latitude and longitude or exact address) and relative location (defined by environmental conditions).
- Place: The physical and human aspects of a location, associated with toponym, site, and situation. Unique characteristics include: Landforms, hydrology, biogeography, pedology, human population, and cultures.
- Human-Environment Interaction: Humans have a profound impact on the environment. Human adaptations have allowed them to dominate other species. This interaction involves dependence, adaptation, and modification.
- Movement: Translocation of human beings, goods, and ideas. Physical movement enabled human colonization of all continents and islands.
- Region: A geographic area with distinctive characteristics. Formal region: Characterized by homogeneity in certain phenomena. Functional or nodal region: Characterized by functional interrelationships in a spatial system.
Location, Shape, and Size of Ethiopia and the Horn of Africa
- The Horn of Africa is a narrow tip in eastern Africa, separating it from the Gulf of Aden.
- Djibouti, Eritrea, Ethiopia, and Somalia are located in the Horn of Africa, each with unique cultures.
- Ethiopia is the largest country in the Horn of Africa, while Djibouti is the smallest.
- The region includes the highlands of the Ethiopian Plateau, the Ogaden desert, the Eritrean and Somali coasts, and has long-standing contact with the Arabian Peninsula and southwestern Asia.
Location of Ethiopia
- Astronomical Location: Ethiopia is a landlocked country located between 3o N (Moyale) and 15o N (Bademe) latitudes and 33o E (Akobo) to 48o E longitudes.
- The east-west distance is 150 meters longer than the north-south distance.
- Latitudinal and longitudinal extensions of Ethiopia result in a tropical climate and a one-hour difference between the most easterly and westerly points.
- The 3-hour-time zone is used for convenience.
- Relative Location: Ethiopia’s location is relative to other countries, landmasses, or water bodies.
Ethiopia’s Location Implications
- Climate: Ethiopia's tropical climate is influenced by altitude and proximity to the Indian Ocean, Atlantic Ocean, and African and Asian landmass.
- Socio-cultural: Ethiopia was an early recipient of Christianity, Islam, and Judaism due to its proximity to the Middle East. Linguistic and cultural relationships reflect the influence of Ethiopia's neighboring countries.
- Political History: Ethiopia's political history has been influenced by superpowers through adjacency to the Red Sea and Middle East geopolitical paradigms.
The Size of Ethiopia
- Ethiopia is the 8th largest country in Africa and the 25th largest globally.
- It extends 1,639 kilometers East-West and 1,577 kilometers North-South.
- Water bodies cover 0.7% of the country.
- Ethiopia's size impacts both its natural and human environment.
The Shape of Ethiopia
- Ethiopia has a compact shape, which offers advantages for defense, socioeconomic, and cultural integration.
- The advantages depend on several other factors.
Special Purpose/Statistical Maps
- These maps show the distribution of various aspects, like temperature, rainfall, settlement, and vegetation.
