The Axis
The straight line between the poles is the Earth's axis of rotation. The curved lines between the poles and along the surface are the meridians of longitude.
The prime meridian
No. The equator is an imaginary line drawn on the Earth's surface, all the way around, mid-way between the north and south poles.
In the globe it is called the axis. In a sphere it is called the diameter.
The straight line connecting the poles is the earth's rotational axis. The lines along the earth's surface from pole to pole are meridians or lines of longitude.
If you mean why planet Earth has a north and a south pole, that's the result of Earth's rotation. The rotation is around an axis; the endpoints of the axis (where this axis goes through Earth's surface) are called north pole and south pole.
The imaginary line that runs through Earth's North and South poles is called the axis or polar axis.
The Earth's axis passes through the North and South Poles. This axis is an imaginary line that runs through the center of the Earth from the North Pole to the South Pole. It is tilted at an angle of approximately 23.5 degrees relative to the plane of its orbit around the Sun, which is what causes the seasons.
The imaginary line passing through the center of the Earth between the North and South Poles, around which the Earth rotates, is called the Earth's axis.
it is if you believe :)
The imaginary line drawn throughout the earth from the North to the South pole is called the Earth's axis. The Earth's axis is tilted at an angle of approximately 23.5 degrees from perpendicular to the plane of the ecliptic, which results in the changing seasons.
