Which location is altitude of Polaris approximately 42?

At which location is the altitude of Polaris approximately 42 degrees? Elmira, cause the altitude of Polaris is 42 and alt of Polaris equals latitude of observer, and only Elmira is near the 42 degree latitude line.

What altitude is Polaris?

Remember that the altitude of Polaris is 0 degrees if you are observing from the equator (0 degrees latitude) and 90 degrees if you are observing from the north pole (latitude 90 degrees), and it is also true for intermediate latitudes.

At which location in New York will Polaris be observed at the highest altitude?

Massena

Where in the world will Polaris have an altitude of 90 degrees?

Note that the Geographical Latitude is 0 deg at Equator, and 90 deg at the North Pole.

Where is the altitude of Polaris the maximum?

North Pole

Is Polaris a 90 degree?

As viewed by observers in the Northern Hemisphere, Polaris occupies a special place. The point in the night sky where the projection of the earth’s axis lies is known as the North Celestial Pole (NCP). At this point (90 degrees latitude), Polaris is 90 degrees above the northern horizon and appears directly overhead.

How accurate is the North Star?

The North Star, also known as Polaris, is known to stay fixed in our sky. It marks the location of the sky’s north pole, the point around which the whole sky turns. That’s because the North Star is really offset a little – by about three-quarters of a degree – from celestial north.

Is latitude equal to altitude?

If you saw Polaris at 30 degrees above the horizon, your latitude would be 30 degrees north. Now for any star reaches its maximum altitude at point lower than the observers zenith, the latitude is equal to 90 – star altitude + star declination.

Why is temperature low at high altitude?

The basic answer is that the farther away you get from the earth, the thinner the atmosphere gets. The total heat content of a system is directly related to the amount of matter present, so it is cooler at higher elevations.

Where is the highest latitude found?

the north pole

What is the lowest latitude possible?

Low latitudes are those locations found between the Equator (0 degrees N/S) and 30 degrees N/S. The middle latitudes are found between 30 degrees N/S and 60 degrees N/S. And the high latitudes are found between 60 degrees N/S and the poles (90 degrees N/S).

What is the longest longitude?

Answer: The longest is the equator, whose latitude is zero, while at the poles, at latitudes 90° north and 90° south (or –90°), the circles shrink to a point.

Which is the longest line of all latitudes?

Equator

What are the 7 major lines of latitude?

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)

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 is the most important line of longitude?

All three lines of latitude are significant in their relationship between Earth and the sun. Running in the opposite direction, north-south, the prime meridian is one of the most important lines of longitude on Earth.

What are 2 important lines of longitude?

1. Prime Meridian = Longitude 0o (Greenwich Meridian). 2. International Date Line (Longitude 180o).

What are the 2 main lines of longitude?

LONGITUDE Lines of longitude run north-south, but provide east-west locational reference. Lines of longitude are called “meridians.” No two meridians are parallel to each other. Rather, all lines of longitude meet at both the North and South Poles, but are separated in between by varying distances.

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.

Where is 180 degrees east 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.

Why is 180 W and 180 e the same line?

The 180th meridian or antimeridian is the meridian 180° both east and west of the Prime Meridian, with which it forms a great circle dividing the earth into the Western and Eastern Hemispheres. It is common to both east longitude and west longitude.

Where is 180 longitude?

The International Date Line, established in 1884, passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth. It is located halfway round the world from the prime meridian—the zero degrees longitude established in Greenwich, England, in 1852.

What is 0 lat 0 long called?

Null Island

Where on earth does the day start?

Greenwich, England

Why is longitude 180 degrees?

180 Degrees Longitude It is used to define the International Date Line. Because the Earth is spherical, traveling 180 degrees in either direction from the prime meridian will lead to 180 degrees longitude or the opposite meridian.

Do longitude lines go up to 90 degrees?

Lines of longitude go from zero at the Prime Meridian up to 180 at the International Date Line. The designator of east or west will indicate the relative direction the line of longitude is from the Prime Meridian.

Is 180 degrees north or south?

In other words, the Earth is 360 degrees around. As we move North-South, we change through 180 degrees. In other words, going from the North Pole to the South Pole is 180 degrees. These spherical coordinates (latitude and longitude) indicate locations on a 3-dimensional representation of the Earth.

What is the name of 90 degrees latitude?

The Equator is the line of 0 degrees latitude. Each parallel measures one degree north or south of the Equator, with 90 degrees north of the Equator and 90 degrees south of the Equator. The latitude of the North Pole is 90 degrees N, and the latitude of the South Pole is 90 degrees S.
