Question

Significance of tropic of cancer dividing into two parts

Answer 1

They match the orientation of the Earth's rotational axis to the ecliptical plane around the sun. ... At the start of winter in the northern hemisphere the sun's rays are only hitting the Earth's surface at a right angle (meaning the sun is directly overhead) at the Tropic of Capricorn.

When the lines were named 2000 years ago, the Sun was in the constellation of Capricorn during the winter solstice and Cancer during the summer solstice (hence the names). ... This means that on December 21, when the Sun is directly over the Tropic of Capricorn at noon, it will not be visible from the Arctic Circle.Jun 20, 2003
