Water covers most of the planet and gets a fraction of the attention land does, which is why marine geography is one of the easier subjects to be confidently wrong about. This quiz works across the whole of it: the oceans and their relative sizes, the seas that sit between particular coastlines, the water bodies whose names describe a colour or a condition rather than a place, and the extremes, the deepest point and the saltiest surface. Sixteen questions. Most of them ask you to locate something rather than define it, which means the reliable strategy is to picture a globe rather than to search your memory for a fact. The one genuine trap is that the naming conventions are inconsistent. Some of these are called seas and are not, one is called a sea and is technically the largest lake on Earth, and a couple of the ocean boundaries were formally agreed far more recently than people assume.
Background and what to expect. No answers given away.
The count is not as settled as school suggests. For most of the twentieth century the standard answer was four, with the water around Antarctica treated as the southern extension of the others. Its recognition as a distinct ocean in its own right is comparatively new and still not universally applied.
Knowing that it is counted, and roughly where its boundary is drawn, is worth a question here.
The word gets applied to enclosed saltwater bodies, to arms of an ocean, and to at least one enormous landlocked lake that is called a sea for historical reasons and is not one. Another famous entry is so saline that almost nothing survives in it, which is where its name comes from rather than from any property of the water itself.
If a question seems to hinge on classification rather than location, this is why.
Most of these questions describe a body of water by what surrounds it: which continents it separates, which countries sit on it, which two land masses it connects. That is a much more answerable format than asking for a name cold.
Picture the map and work outwards from the coastlines mentioned. Almost every answer here is reachable that way.
Marine geography has a small set of superlatives that everybody half-knows: the largest ocean, the deepest trench, the saltiest surface water. They are famous enough to feel easy and specific enough to be worth checking.
The deepest point in particular sits inside one specific ocean, and picking the wrong ocean is a common mistake.
The names lie. Several of these water bodies are classified as something other than what they are called, and a few of the questions turn on knowing the technical status rather than the label.
