The Antarctic Circle is a parallel of latitude on the Earth at approximately 66.5 degrees south of the equator. On the day of the southern summer solstice (around December 22 each year), an observer on the Antarctic Circle will see the Sun above the horizon for a full 24 hours.
What is 23.5 latitude called?
Tropic of Cancer: 23.5 degrees north of equator. Tropic of Capricorn: 23.5 degrees south of equator.
What are the 5 major latitude lines?
Important lines of latitude:
- the equator (0°)
- the Tropic of Cancer (23.5° north)
- the Tropic of Capricorn (23.5° south)
- the Arctic circle (66.5° north)
- the Antarctic circle (66.5° south)
- the North Pole (90° north)
- the South Pole (90° south)
What is the major latitude?
The five major parallels of latitudes from north to south are called: Arctic Circle, Tropic of Cancer, Equator, Tropic of Capricorn, and the Antarctic Circle.
Which is longest parallel?
The equator is the circle that is equidistant from the North Pole and South Pole. It divides the Earth into the Northern Hemisphere and the Southern Hemisphere. Of the parallels or circles of latitude, it is the longest, and the only ‘great circle’ (a circle on the surface of the Earth, centered on Earth’s center).
What if the Earth’s tilt was 10 degrees?
If the Earth’s tilt were at 10 degrees instead of 23.5 degrees, then the Sun path through the year would stay closer to the equator. … So the new tropics would be between 10 degrees north and 10 degrees south, and the Arctic and Antarctic circles would be at 80 degrees north and 80 degrees south.
Is latitude N or W?
Latitude is the measurement of distance north or south of the Equator. It is measured with 180 imaginary lines that form circles around the Earth east-west, parallel to the Equator.
What are the four hemispheres called?
There are generally considered to be four hemispheres: Northern, Southern, Eastern, and Western.
What is the other name of 661 2 north latitude?
They include: • the Arctic Circle at 661/2° north • the Antarctic Circle at 661/2° south • the Tropic of Cancer at 231/2° north • the Tropic of Capricorn at 231/2° south Longitude is distance, measured in degrees, east and west of the prime meridian. Lines of longitude join the poles in a north-south direction.
Why do we have 360 longitudes and only 181 latitudes?
Longitude lines runs from North to south pole means a complete circles and hence covers 360 degrees and that is why there are 360 longitudes. … Each section from equator to pole is 90 degrees and two poles have 2 quarters of circle/globe hence 90X2 180 lattitudes. adding the Equator it becomes 181 latitudes.
Which is the longest longitude?
Lines of longitude (meridians) running north-south around the globe measure distances EAST and WEST of the Prime Meridian. Directly on the opposite side of the earth from the prime meridian is located the 180 meridian. This is the highest longitude possible.
What is the name of the line at 66 33 39 S?
The middle latitudes (also called the mid-latitudes, sometimes midlatitudes, or moderate latitudes) are a spatial region on Earth located between the latitudes 23°26’22” and 66°33’39” north, and 23°26’22” and 66°33’39” south.
Which is the largest parallel on the globe?
The largest parallel is at the equator, and the parallels decrease in size towards the poles. Except for positions located right on the equator (0°), parallels of latitude are described by the number of degrees that they are north (N) or south (S) of the equator.
What if Earth’s tilt was 90 degrees?
But if Earth’s axis tilted to 90 degrees, extreme seasons would cause intense climate change on every continent. During the summer, the Northern Hemisphere would experience nearly 24 hours of sunlight for months, which could melt ice caps, raise sea levels, and flood coastal cities.
What if Earth didn’t have a tilt?
If earth did not tilt and orbited in an upright position around the sun, there would be minor variations in temperatures and precipitation throughout each year as Earth moves slightly closer and farther away from the sun. … Earth would be warm at the equator and cold at the poles.
What would happen if the Earth stopped rotating?
At the Equator, the earth’s rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.
What is the 0 line of longitude?
The meridian that runs through Greenwich, England, is internationally accepted as the line of 0 degrees longitude, or prime meridian. The antimeridian is halfway around the world, at 180 degrees. It is the basis for the International Date Line.
How many meridians are there in total?
There are 360 meridians– 180 to the east and 180 to the west of the Prime Meridian. The meridians in the Eastern Hemisphere are marked as ‘E’ and meridians in the Western Hemisphere are marked as ‘W’.
Why there are 180 latitudes and 360 longitudes?
Latitude lines are comprehensive circles, with the middle at 0° and the pole at 90°. The South Pole and the North Pole have separated by 180° apart, The longitude lines cross from the North Pole to the South Pole. … This is why it begins at zero and finishes at 360 longitudes.
Is latitude vertical or horizontal?
It is at 0 degrees longitude. Hemisphere – one half of the planet Page 8 Latitude – horizontal lines on a map that run east and west. They measure north and south of the equator. Longitude – the vertical lines on a map that run north and south. They measure east and west of the Prime Meridian.
What are the 4 types of latitude?
Latitude is a measurement on a globe or map of location north or south of the Equator. Technically, there are different kinds of latitude—geocentric, astronomical, and geographic (or geodetic)—but there are only minor differences between them. In most common references, geocentric latitude is implied.
