World Geography Quiz | Intermediate Climate, Rivers and Tectonics

Dry summers and wetter winters are the classic signature of a Mediterranean climate. An oceanic climate generally has rain all year, a tropical rainforest climate is hot and wet, and a tundra climate is defined mainly by cold.

The rain shadow of the Andes, the cold current along the coast and persistent high pressure that keeps depressions out combine to intensify the aridity of the Atacama. It is better understood as a combination of factors than as the cold current alone.

The Sahel is the semi-arid transitional belt running east to west along the southern edge of the Sahara. Its boundaries are not a single fixed line but a zone where rainfall and vegetation change continuously.

All four cities are capitals on the main course of the Danube, which finally empties into the Black Sea. The Rhine and the Elbe both flow to the North Sea, so neither matches the destination either.

The Bosphorus links the Black Sea to the Sea of Marmara. From there the Dardanelles lead on to the Aegean and the Mediterranean. The Strait of Gibraltar is at the western end of the Mediterranean.

The river that runs through six countries and forms a large delta in southern Vietnam is the Mekong. The Yangtze stays within China and empties into the East China Sea, and the Ganges flows mainly through India and Bangladesh.

In the East African Rift the continental crust is being stretched, producing faulting, volcanic activity and long narrow rift lakes. The clue is that fault scarps and volcanoes line up in the same belt as the lakes, not just the lakes.

Brazil's official language is Portuguese. Many South American countries have Spanish as their official language, but Brazil's linguistic geography differs because of its history as a Portuguese territory.

Off Java the Australian Plate is subducting beneath the Sunda Plate, and the trench, the earthquakes and the volcanic activity go together. The whole of Indonesia's complex tectonics cannot be explained by one boundary alone, but this fits the conditions given for Java.

Lake Baikal lies in south-eastern Siberia and is held to be the oldest and deepest lake in the world. The Caspian Sea is enormous in area but does not meet all three conditions here of age, depth and location.
