Reading maps and scale
A map is a scaled-down drawing of the real world. The scale tells you how many times smaller, so you can work out real distances.

A map is a scaled-down drawing of the real world. The scale tells you how many times smaller, so you can work out real distances.
With the eight compass directions and the degrees of a compass you say exactly where a place lies: Antwerp is north of Brussels, Namur south-east.
With latitude (north or south of the equator) and longitude (east or west of Greenwich) you give every place on earth its own address.
Belgium has three regions and ten provinces, each with a capital. Big rivers such as the Scheldt and the Meuse flow through the country to the North Sea.
Belgium lies in Western Europe, between the Netherlands, Germany, Luxembourg and France. Important institutions of the European Union work in Brussels.
Day and night, time zones, the seasons, weather and climate, and the climate zones.
The earth turns around once in about 24 hours, from west to east. The side facing the sun has day. That is why clocks elsewhere show a different time.
The earth's axis is tilted by about 23.5°. So each hemisphere in turn leans towards the sun and away from it: summer and winter. The distance to the sun is not the cause.
Weather is the state of the air right now, climate the average over about 30 years. A climate chart shows each month's temperature as a line and precipitation as bars.
The closer to the equator, the warmer; the closer to the pole, the colder. That gives climate zones: tropical, dry, temperate, cold and polar. Belgium lies in the temperate zone.
Contour lines, rivers and the water cycle, the coast, volcanoes and earthquakes.
Contour lines join points at the same height. They let you read on a flat map how high a hill is and where it gets steep.
Water evaporates, forms clouds, falls as rain and flows back to the sea through rivers. That way the water keeps going round.
At the Belgian coast the sea rises and falls about twice a day. Dunes and dykes protect the low polder land behind it.
The earth's crust is made of plates that move slowly. Where they move apart or collide, volcanoes, mountains and earthquakes form.
Population and cities, farming and food, mobility and caring for the climate.
Population density is the number of inhabitants per km². In cities many people live close together, in the countryside there is more space.
Every Belgian region has its own farming, and every season its own harvest. Food from nearby and in season travels fewer kilometres.
How long you are on the way depends on the distance and the speed. On foot, by bike, bus, train or car: every choice has pros and cons.
Greenhouse gases keep heat near the earth. Burning more coal, oil and gas makes it warmer on average. Together we can do a lot about it.
