Equator vs. Tropics: What's the Difference?

By Harlon Moss & Janet White || Updated on May 21, 2024
The Equator is an imaginary line around the middle of the Earth, dividing it into Northern and Southern Hemispheres, while the Tropics refer to the regions between the Tropic of Cancer and the Tropic of Capricorn, characterized by a warm climate.

Key Differences

The Equator is an imaginary line that encircles the Earth at 0 degrees latitude, marking the midpoint between the North and South Poles. This line divides the Earth into the Northern and Southern Hemispheres. The Tropics, on the other hand, are the regions of the Earth located between the Tropic of Cancer at approximately 23.5 degrees North and the Tropic of Capricorn at approximately 23.5 degrees South. These areas are characterized by their warm temperatures and seasonal rainfall patterns.
The Equator's climate is heavily influenced by its consistent solar exposure, resulting in minimal temperature variation throughout the year. In contrast, the Tropics, though also warm, can have more varied climatic conditions due to the influence of monsoons, trade winds, and other meteorological factors.
Geographically, the Equator crosses landmasses and bodies of water, including parts of South America, Africa, and Asia. Meanwhile, the Tropics encompass a larger area, covering parts of all continents and including diverse ecosystems like rainforests, savannas, and deserts.
In terms of cultural and ecological significance, the Equator hosts unique biodiversity hotspots such as the Amazon Rainforest. Conversely, the Tropics also support rich biodiversity and various human cultures adapted to tropical climates, such as those in Southeast Asia, Central America, and parts of Africa.

Equator and Tropics Definitions


A region known for its hot and humid climate.
Equatorial regions often have lush rainforests.


Encompasses diverse ecosystems.
Savannas, rainforests, and deserts are all found in the Tropics.


The imaginary line dividing Earth into Northern and Southern Hemispheres.
The Equator runs through several countries in South America and Africa.


Regions between the Tropic of Cancer and Tropic of Capricorn.
The Tropics are known for their warm weather year-round.


Earth’s widest circumference.
The Equator is the longest latitude line on Earth.


Zones with a variety of climates, often warm and wet.
Tropical rainforests are found within the Tropics.


Line of latitude at 0 degrees.
Quito is one of the major cities near the Equator.


Area characterized by high biodiversity.
Many unique species thrive in the Tropics.


Point of equal distance from the North and South Poles.
Day and night are almost equal in duration at the Equator.


Parts of Earth receiving direct sunlight at least once a year.
The sun is directly overhead in the Tropics during solstices.


The imaginary great circle around the earth's surface, equidistant from the poles and perpendicular to the earth's axis of rotation. It divides the earth into the Northern Hemisphere and the Southern Hemisphere.


Plural of tropic


A similar great circle drawn on the surface of a celestial body at right angles to the axis of rotation.


(geography) The region of the Earth centred on the equator and lying between the Tropic of Cancer and the Tropic of Capricorn and characterized by a hot climate.


The celestial equator.


The part of the Earth's surface between the Tropic of Cancer and the Tropic of Capricorn; characterized by a hot climate


A circle that divides a sphere or other surface into congruent parts.


An imaginary great circle around Earth, equidistant from the two poles, and dividing earth's surface into the northern and southern hemisphere.


(astronomy) A similar great circle on any sphere, especially on a celestial body, or on other reasonably symmetrical three-dimensional body.


The midline of any generally spherical object, such as a fruit or vegetable, that has identifiable poles.
Slice the onion through the equator.


The celestial equator.


The imaginary great circle on the earth's surface, everywhere equally distant from the two poles, and dividing the earth's surface into two hemispheres.


The great circle of the celestial sphere, coincident with the plane of the earth's equator; - so called because when the sun is in it, the days and nights are of equal length; hence called also the equinoctial, and on maps, globes, etc., the equinoctial line.


An imaginary line around the Earth forming the great circle that is equidistant from the north and south poles;
The equator is the boundary between the northern and southern hemispheres


A circle dividing a sphere or other surface into two usually equal and symmetrical parts
