Sagging Power LinesIn the summer, power lines warm up with the weather. Since materials expand when they get warm, the power lines stretch out and sag. The opposite happens in the winter, as the power lines get colder, they contract. Also, in the summer the electrical load on the line is generally greater. This in turn causes increased temperature and can lead to the line sagging.
the metal inside the wire heats up leading to the expansion of the wire.
Wow, no. There is not. Check out the lines of latitude.
equator prime meridian
The Tropic of Cancer and the Tropic of Capricorn.
Every point along the same line of latitude has the same amount of time between sunrise and sunset at any given moment. That amount of time grows gradually shorter from the time of the summer solstice until the time of the winter solstice, and it grows gradually longer from the winter solstice until the summer solstice. Also, higher altitudes at the same latitude and longitude will see the sun slightly longer.
The Antarctic Circle is parallel to the Arctic Circle, as they both mark the latitudes at approximately 66.5 degrees north and south, respectively. These circles denote the points where the sun does not set on the summer solstice and does not rise on the winter solstice.
It is when the Earth lines up with the sun, causing the oceans waves to grow larger and destroy towns. This is because of the wind patterns blowing hot air into the water.
They are specially marked because, they are the most north and south on the lines of latitude. During the summer solstice, the sun beams directly on these points ( the two arctic circles)
The imaginary lines that run around the Earth south of the equator are called lines of latitude, specifically referred to as degrees south latitude. They are measured in degrees from the equator (0 degrees latitude) to the South Pole (90 degrees south latitude).
Either the Tropic of Cancer or the Tropic of Capricorn. BTW -- they're lines of latitude, not longitude.

The northernmost point on Earth is the geographic North Pole, located at 90 degrees north latitude. It is the point where all lines of longitude converge, and it experiences 24 hours of daylight during the summer solstice in June.
On June 21, the most direct rays strike the Tropic of Cancer, which is located at approximately 23.5 degrees north latitude. This marks the summer solstice in the Northern Hemisphere. At this time, the North Pole is tilted towards the Sun, causing the Sun's rays to hit the Earth most directly in that region.
Latitudinal lines never meet as the are circumference lines. However, Longitudinal lines meet at the North & South poles. Zero Longitude goes through Greenwich which is also where Greenwich Mean Time (GMT) comes from. GMT is British winter time as opposed to British Summer Time which is GMT +1 hour.
The Tropics of Cancer and Capricorn are imaginary lines located at 23.5 degrees north and south of the equator, respectively. They mark the northernmost and southernmost points where the sun appears directly overhead at least once a year, leading to the longest days (summer solstice) in the Northern Hemisphere and the shortest days (winter solstice) in the Southern Hemisphere.
