Bulgaria DZI Geography study guide
Bulgaria DZI Geography · Work through your exam, one topic at a time.
The Bulgarian State Matriculation Exam (DZI, държавен зрелостен изпит) in Geography and Economics is a national school-leaving examination taken by students completing secondary education in Bulgaria. It functions both as a graduation requirement option and as a score used in university admission, so candidates often sit it when applying to programmes in geography, economics, tourism, regional development or teaching. The Bulgaria DZI Geography study guide has 10 sections and about 3,217 words.
01General Geography and Cartography
General geography asks you to connect physical and human systems; cartography asks you to read the map that shows them. Master the basics: Earth as a geoid, latitude and longitude, the graticule, hemispheres, the poles and the equator, and the difference between absolute location (coordinates) and relative location (position described against other features).
329 words, about 2 min02Lithosphere
The lithosphere is the rigid outer shell (crust plus uppermost mantle) broken into plates. Know the layered Earth: crust (continental, granitic and thicker; oceanic, basaltic and denser), mantle, outer core (liquid) and inner core (solid).
286 words, about 1 min03Relief and Tectonics
Relief is shaped by internal forces (tectonism, volcanism) and external forces (weathering, erosion, deposition). Endogenic processes raise land; exogenic processes wear it down.
265 words, about 1 min04Atmosphere and Climate
The atmosphere is layered: troposphere (weather), stratosphere (ozone layer), mesosphere, thermosphere. Insolation varies with latitude and season because of Earth's axial tilt (about 23.5°).
265 words, about 1 min05Hydrosphere and Water Resources
Water moves through evaporation, transpiration, condensation, precipitation, infiltration, runoff and storage. Oceans hold most of Earth's water; only a small share is fresh, and much of that is locked in ice.
260 words, about 1 min06Biosphere
The biosphere is the zone of life. In ecosystems, producers (plants) capture solar energy, consumers eat, and decomposers recycle nutrients.
262 words, about 1 min07Soils and Natural Zones
Soil forms from parent material acted on by climate, organisms, relief and time. A soil profile has horizons (O, A, B, C, R).
260 words, about 1 min08Population and Demography
Demography studies population size, structure, distribution and change. Change equals natural increase (births minus deaths) plus net migration.
254 words, about 1 min09Settlements and Urbanisation
Settlements are rural or urban, dispersed or nucleated, and their sites reflect water, defence, transport, relief and resources. Site is the exact location; situation is the position relative to surrounding features.
239 words, about 1 min10World Economy and Economic Sectors
The economy is divided into primary (extraction), secondary (manufacturing), tertiary (services) and quaternary (knowledge and research) sectors. As economies develop, employment shifts from primary to secondary to tertiary; this is the sectoral shift.
