The tropics account for 36 percent of the Earth’s landmass and are home to about a third of the world’s people. The tropics are warm all year, averaging 25 to 28 degrees Celsius (77 to 82 degrees Fahrenheit). This is because the tropics get more exposure to the sun.
Why is 23.5 degrees latitude so important?
The reason for the location of the Tropic of Cancer and the Tropic of Capricorn at roughly 23.5 degrees north and south, respectively, is due to the axial tilt of the Earth. The Earth is tilted 23.5 degrees from the plane of the Earth’s revolution around the sun each year.

What is special about the Arctic and Antarctic circles?The length of continuous day or night increases northward from one day on the Arctic Circle to six months at the North Pole. The Antarctic Circle is the southern counterpart of the Arctic Circle, where on any given date conditions of daylight or darkness are exactly opposite.
Article first time published onIs the Tropic of Cancer north or south of the equator quizlet?
The Tropic of Cancer is north of the equator and runs through Mexico, the Bahamas, Egypt, Saudi Arabia, India, and southern China. The Tropic of Capricorn is south of the equator and runs through Australia, Chile, southern Brazil (the only country that passes through both the equator and the tropic), and South Africa.
What are mountains influence on climate and weather?
Mountains as rain makers and rain takers The mountains create a barrier to air moving eastward off the Pacific Ocean. When the moist, oceanic air encounters the mountains it begins to rise. The rising air cools as it moves up and over the mountains, and much of its moisture condenses, forming clouds and precipitation.
Why are the tropics hotter than the equator?
This is because as the dry air descends from high altitudes, its compression leads to an increase in its temperature. … Therefore, air temperature in the tropics (42 degrees Celsius) is greater than that of the Equator (30 degrees Celsius). This is why tropical regions are hotter than the Equator.
Why is the equator important?
The equator is a very important “imaginary line” for the GOES and GOES-R weather satellites. They orbit exactly above the equator, at a very great distance (22,300 miles), which allows them to make just one orbit per day.
Is the Tropic of Capricorn a great circle?
Any circle that passes through two points that are opposite each other on a sphere. … The Equator is a great circle, but the Tropics of Cancer and Capricorn are not (they are smaller than the Equator). And the Arctic and Antarctic Circles are even smaller than the Tropics and definitely not great circles.
How many countries lie on the Tropic of Capricorn?
1.4: Countries that the Tropic of Capricorn passes through There are 10 countries, 3 continents and 3 water bodies through which the Tropic of Capricorn passes.
Does Tropic of Capricorn passes through India?
The Tropic of Capricorn does not pass through India. The three imaginary lines running across the globe are the Equator, Tropic of Cancer and Tropic of Capricorn. … Its northern hemisphere is Tropic of Cancer.
What is the importance of Tropic of Capricorn Class 6?
Answer: The Tropic of Capricorn is significant to understanding the Earth’s geography because it marks the southern boundary of tropics. This is the region that extends from the equator south to the Tropic of Capricorn and north to the Tropic of Cancer.
Is Tropic of Capricorn North or south?
The Tropic of Capricorn lies at 23d 26′ 22″ (23.4394 degrees) south of the Equator and marks the most southerly latitude at which the sun can appear directly overhead at noon.
What is the significance of these lines of latitude?
Lines of constant latitude, or parallels, run east–west as circles parallel to the equator. Latitude is used together with longitude to specify the precise location of features on the surface of the Earth.
What hemisphere is Australia?
Powered by The Northern Hemisphere contains North America, the northern part of South America, Europe, the northern two-thirds of Africa, and most of Asia. The Southern Hemisphere contains most of South America, one-third of Africa, Australia, Antarctica, and some Asian islands.
What three countries lie on the equator?
The Equator passes through 13 countries: Ecuador, Colombia, Brazil, Sao Tome & Principe, Gabon, Republic of the Congo, Democratic Republic of the Congo, Uganda, Kenya, Somalia, Maldives, Indonesia and Kiribati.
Does the equator pass through Australia?
1. The equator passes through the continents of South America, Africa and Asia. … Australia is sometimes known as an ‘island continent.
What would happen if the composition of the atmosphere changed?
Changes in atmospheric composition and the rest of the climate system would include temperature, rainfall, and humidity, which would affect the economic importance, geographical distribution, and management of diseases effecting crop production.
How has the composition of Earth's atmosphere changed over time briefly outline the evolution of Earth's atmosphere?
When earth was first formed, its atmosphere was likely composed of hydrogen, helium, and other gases that contained hydrogen. … Over a vast amount of time, millions of years, the earth gradually cooled. When the temperature dropped enough, water vapor condensed and went from a gas to liquid form. This created clouds.
How has the surface of the earth changed over time?
Earth’s surface is constantly changing. Wind, water, and ice break down large rocks and move sediments on the surface. It usually takes years for weathering, erosion, and deposition to cause noticeable changes. Some events, though, change Earth’s surface much more quickly.
At what latitude is the Antarctic Circle and what is its significance?
