Geography quizzes
Countries, capitals, rivers, mountains
From the sources of the Danube to the mouth of the Mississippi, from the peaks of the Himalayas to the dunes of the Sahara, geography describes the Earth and the ways people live on it. This theme covers countries and their capitals, rivers, seas and oceans, mountain ranges, climates, time zones and the essential tools for reading a map: latitude, longitude, scale and compass points.
You can test yourself on orientation, relief and location, whether the task is placing Lake Baikal, naming a country's capital or understanding why the equator is hot. These geography quizzes are free and offer five levels, from very easy to expert, with an explanation after every answer to help the facts stick.

Frequently asked questions about Geography
How do latitude and longitude work?
Latitude measures the angular distance north or south of the equator, from 0° to 90°. Longitude measures the distance east or west of the Greenwich meridian, from 0° to 180°. Together, these two coordinates, given in degrees, pinpoint any location on the globe.
How are mountains formed?
Most major mountain ranges form when tectonic plates collide. The Himalayas rose where the Indian plate met the Eurasian plate, and they are still slowly growing. The Alps also result from the African and Eurasian plates pushing together.
Why are there time zones?
The Earth turns once in 24 hours, which is 15 degrees of longitude per hour. The globe is therefore divided into zones of about 15 degrees, each one hour apart from its neighbour. The reference zone follows the Greenwich meridian (UTC), although some countries use offsets of 30 or 45 minutes.
