The Cancer Tropic and the Capricorn Tropic The Tropic of Capricorn goes across Australia, Chile, southern Brazil (the only nation that travels through both the equator and a tropic), and northern South Africa. The tropics, on the other hand, may be frigid. In Antarctica, for example, ice caps cover most of the continent, and sea water flows in large channels between the ice sheets. The Antarctic Peninsula, where part of Argentina borders the South Atlantic Ocean, is becoming more exposed to the open ocean due to rising sea levels caused by climate change. Scientists are concerned that this will lead to faster melting of the ice sheet.
North America travels through two tropics: the Tropical Zone at the equator and the Temperate Zone at 40 degrees north latitude. These zones are defined by different types of vegetation that depend on the temperature and amount of precipitation. Plants in the tropical zone, such as coconut palms, banana trees, and bamboo, have spiky leaves and soft thick stems that store energy food during the winter when there is no rain. Trees in the temperate zone, like those found in northern forests, have thin, waxy leaves that protect them from the cold weather. Their trunks and branches are covered with scars from past fires since tree growth is slow in this environment.
Tropical storms form in the Caribbean Sea and Atlantic Ocean where they are fed by warm air and moisture from the Gulf of Mexico.
The Tropic of Cancer is its northern counterpart. The Tropic of Capricorn is one of the five primary latitude circles depicted on maps of the Earth... all over the globe.
| Co-ordinates | Country, territory or ocean | Notes |

Cancer Tropic: 23.5 degrees north of the equator. Capricorn's Tropic is located 23.5 degrees south of the equator. Antarctic circle: 23.5 degrees south of the equator.
On a map of the Earth, the Tropic of Capricorn, often known as the Southern Tropic, is one of the five primary circles of latitude. It is 23 degrees 26 minutes and 22 seconds south of the Equator. Countries across which the Tropic of Capricorn passes The Tropic of Capricorn is home to ten countries, three continents, and three bodies of water. Argentina, Brazil, and Chile are in South America. Paraguay, Uruguay, and Italy are in Europe. Monaco, France, and Switzerland are in Europe and Africa. Algeria, Egypt, Israel, Jordan, Libya, Morocco, Palestine, Tunisia, and Turkey are in North Africa.
The Tropic of Capricorn runs through some interesting places. It passes through the southernmost city in Australia - Sydney. It also passes through the southernmost city in New Zealand - Wellington. And it crosses into Antarctica just north of the South Pole.
Geographically, the tropics are areas of the Earth's surface and ocean where the average annual temperature is always about 72 degrees F (22 degrees C). Tropical climates are characterized by relatively constant mild temperatures throughout the year, with no real seasons. Daytime temperatures rarely drop below 48 degrees F (9 degrees C) or rise above 86 degrees F (30 degrees C), and night-time temperatures seldom exceed 75 degrees F (24 degrees C).
Tropical storms and hurricanes are common in the tropics. They are large-scale systems of clouds and rain activity that develop in the tropical oceans. These storms can cause a great deal of damage when they move inland.
The Tropic of Cancer is found north of the equator, around the parallel of 23.5 degrees north latitude. It marks the northernmost point of the tropics. The Tropic of Capricorn (about 23.5° South latitude) is the comparable line in the Southern Hemisphere. These are the only two regions on Earth where the sun rises and sets at the same time every day throughout the year.
The angle between the Equator and either of these lines is about 90 degrees. If we draw a circle with this as its radius, it will cover all parts of the globe except for the polar regions.
The reason why these lines are important to study when looking at cancer rates is that the intensity of sunlight changes throughout the year, especially near the equator where there is no real winter or summer. As a result, vitamin D production depends upon how much sunlight you can afford to be outside without burning. Vitamin D plays an important role in preventing cancer, so people who don't get enough of it are likely to develop more cancers later in life.
There is also some evidence that breast cancer rates are higher near the Arctic than near the Antarctic, probably because of differences in hormone levels due to the length of daylight during the winter months. But these variations are so small that they may not be able to be detected by studying just one country or region within those areas.
The tropics are located between the latitude lines of the Tropics of Cancer and Capricorn. The Equator and sections of North America, South America, Africa, Asia, and Australia are all part of the tropics. The tropics cover 36% of the Earth's area and are home to around one-third of the world's population.
The term "tropical" comes from the Latin word for south, tropicalis, which in turn comes from the Greek word for the same thing, τρόποικος. Thus, "tropical" means "of or relating to the south". The first written record of the term appears in 1556 by Martin Waldseemüller who used it to describe regions that now include much of Africa and South America.
Tropical climates are characterized by their sensitivity to changes in temperature, with a wide variation in daily temperatures. They occur near the equator and in certain other high-latitude regions. Tropical climates can be further classified by which hemisphere they are located in: northern tropical climates are those located in the Northern Hemisphere, while southern tropical climates are those located in the Southern Hemisphere.
There are two types of tropical climates: monsoon and desert. A monsoon climate is defined as having both a dry season and a wet season. During the dry season, there is less than 10 inches of rain per year whereas during the wet season, this increases to over 10 inches of rain per year.
