Geography

Our planet, countries, climate and nature

You will learn how our planet is built and how it moves, how to read maps and coordinates, and how landforms, climate, water and natural zones are formed. Then you will connect this knowledge with continents, countries and population, and with the nature and economy of Azerbaijan.

7 lessons
  1. 1Earth’s shape, size and rotationLearn the Earth’s shape and size and the evidence for them, how the Earth spins from west to east, and what follows from it: day and night, time differences, the deflection of moving bodies and the speed of rotation at different latitudes.
  2. 2Earth’s orbit, the noon Sun angle and illumination beltsLearn about Earth’s orbit, the real cause of the seasons, solstices and equinoxes; calculate the noon Sun angle with h = 90° − |φ − δ|, find the latitude from an angle, and explain polar day and night and the five illumination belts.
  3. 3Maps and scaleLearn how a globe, a plan and a map differ, the types of maps, the three forms of scale, map symbols and ways of showing information, and how to calculate distances, scales and areas.
  4. 4Plans of an area, azimuth and contour linesLearn to read and draw a plan of an area, find directions, work out azimuths and back azimuths, read heights from contour lines, find the relative height of a hill and build an A–B relief profile.
  5. 5Latitude and longitudeGet to know the grid of parallels and meridians and learn to find the geographic coordinates of any place.
  6. 6The degree grid and distance calculationsLearn to turn degrees into kilometres along meridians and parallels: 1° of a meridian is 111 km, while 1° of a parallel depends on the latitude. Find the shortest route over a pole, the size of Azerbaijan and a map’s scale from the degree grid.
  7. 7Local time and time zonesLearn how the Earth’s rotation is linked to time, how time zones are numbered from 0 to XXIII, the difference between local, zone and official time, how the date line works, and how to solve DİM-style time problems.
