These countries sit right on the equator

The equator is the invisible line at zero degrees latitude that splits the Earth into north and south. Across the globe it crosses the mainland of exactly eleven countries, spread over three continents. Know them, and you clear quiz points by the row, because this question shows up in almost every geography test. The key is to separate countries whose mainland the line actually touches from those it only skims at sea.

Three countries in South America

In South America the equator crosses Ecuador, Colombia and Brazil. Brazil is by far the largest country on the line, with the northern Amazon basin sitting right on it. Ecuador is the star: its name is simply the Spanish word for equator. Colombia is grazed in the south, far from the capital Bogota, deep in thinly settled rainforest.

Seven countries in Africa

Africa has the highest density. The line runs through:

• Sao Tome and Principe: the small island state in the Gulf of Guinea.
• Gabon, Republic of the Congo, DR Congo: straight through the central African rainforest.
• Uganda, Kenya, Somalia: the hop across East Africa to the coast.

The rest in Asia

In Asia the equator crosses the mainland of only one country on this list: Indonesia, whose islands spread on both sides of the line. Sumatra, Borneo and Sulawesi are all grazed, with the line threading through the largest island nation on Earth. The Maldives sit extremely close, with the equator passing just south of their southernmost atoll through their waters without touching land. The same goes for the Pacific nation of Kiribati: there too the line runs only through the waters, not across land. Exactly these borderline cases make the topic tricky in a quiz.

Why it stays so hot there

At the equator the sun stands very high all year, so there are barely any seasons in the European sense. Instead of summer and winter, wet and dry periods take turns. Days run at roughly twelve hours throughout, with almost no swing across the year, and tropical rainforest thrives in exactly this belt. Altitude can flip that, though: Quito in Ecuador sits almost on the line yet stays cool, because the city perches high in the Andes. So the heat does not depend on latitude alone, but also on how high a place lies.

A memory hook for the quiz

Eleven countries sounds like a lot, yet they line up cleanly: three in South America, seven in Africa and one in Asia. Remember that split and you already hold half the answer. A small crutch:

• South America: Ecuador, Colombia, Brazil, from west to east.
• Africa: the arc from the Atlantic coast across the Congo basin to Somalia on the Indian Ocean.
• Asia and the Pacific: only Indonesia has land on the line, while the Maldives and Kiribati are crossed through water alone.

The Maldives and Kiribati are the classic traps here: they sit so close that many count them in, even though the equator runs only through their waters and not across their land. Exactly these fine points separate the wheat from the chaff in a quiz.

Eleven countries, three continents, one line: a pattern that is easy to lock in. In CountryRush you can practise these countries by outline and capital and quickly see how tightly geography and climate are linked.
