Question: Show the lines of longitude on the globe when your teacher ask you?

Lines of longitude, also known as meridians, are the imaginary lines that run from the North Pole to the South Pole on a globe. They are essential for determining the east or west position of a location on Earth. Each line of longitude is measured in degrees, with the prime meridian, which is 0° longitude, serving as the reference point. This prime meridian passes through Greenwich, London, and from there, the lines of longitude extend east and west up to 180°. When showing these lines on a globe, one would start at the prime meridian and count each line until reaching the specified degree of longitude. For example, if a teacher asks to show 30° E longitude, you would locate the prime meridian and count 30 lines to the east. This system of coordinates, comprising both latitude and longitude, allows for the precise pinpointing of any location on Earth's surface.
