hemisphere
An equator is a circle that divides the surface of an object into two equal halves. The term is usually used to explain the circle that divides a plane,t like the Earth, in to two hemispheres.
diameter
Only the diameter can divide the circle in to two equal parts.
A line segment that divides a circle in two is a chord.If the two parts of the circle are equal, the line segment is a diameter.See 'The Parts of the Circle' in Sources and related links, below.
The Equator divides the Earth into the Northern Hemisphere and the Southern Hemisphere. Lines of latitude are parallel to the Equator both to the north and to the south.
A cut through any great circle does.
great circle
That line is called a "Diameter".
prime merideane and equator The equator divides the earth into two equal halves.
The imaginary line that cuts the earth into two equal parts is called the equator. It is an imaginary circle around the Earth that is equidistant from the North and South poles. It divides the Earth into the Northern Hemisphere and the Southern Hemisphere.
A chord is a straight line within a circle that divides the circle into two parts - these parts are called arcs.The diameter is a chord that runs through the centre of the circle and divides the circle into two equal parts.
The parallel is called the equator.
It is called a great circle. The equator is an example.

The equator divides the Earth into two equal parts, the northern and southern hemispheres. The prime meridian divides the Earth into the equal eastern and western hemispheres.
