The lines of latitude and longitude.
An invisible line that forms east-west circles around the Earth is called both parallel and line of latitude. An imaginary line that circles the earth from north to south is called both meridian and line of longitude.
You're thinking of 'parallels of constant latitude'.
That could be a description of the parallels of latitude. They're not only invisible, they're also totally imaginary.
They are called lines of "latitude".
Because they make big circles around the Earth.
The invisible lines around the earth are called lines of latitude and longitude. Lines of latitude run east-west and measure the distance north and south of the equator, while lines of longitude run north-south and measure the distance east and west of the Prime Meridian. These lines help in locating specific points on Earth's surface.
The three main invisible lines around the Earth are the Equator, the Tropic of Cancer, and the Tropic of Capricorn. These lines help determine important geographic phenomena such as climate zones and the changing of seasons.
They are the lines of latitude and longitude.
Lines of latitude are any of the circles, called parallels, that are to the north or to the south of the equator and parallel to it. They are the lines on standard maps that go from east to west; right-left.It is an imaginary line around the Earth parallel to the equator.
Latitude
You are referring to the Equator, which bisects the earth into the Northern and Southern Hemispheres. It is located at 0 degrees latitude. In addition, there are innumerable lines of longitude that make complete circles around the earth, that run north and south.
Latitude and LongitudeLatitude is the lines that go from east to west, and longitude from north to south.
