You are probably thinking of latitude, which shows distance from the equator as the angle subtended by the arc between the place and the nearest point on the equator. For instance, the latitude of London, United Kingdom, is 51.5 degrees N.
You could use a weather vane
The equator of the Earth
My grandma lives close to the equator.

The Equator divides the planet into northern and southern hemispheres.
The equator splits up half of the earth. The equator is a line that splits half of the earth
The Red Sea is North of the Equator.
yes, you just even used it in a question. like the equator is.....
It's not "used" for anything.
draw a set of diagrams to help explain this. (Use red arrows to show the direction of hot air blue arrows to show the direction of cold air.) Match up words to the meanings. Draw a line to join them up.
The absolute direction of rotation is always the same (from East to west). How we describe that direction depends on the frame of reference we use. Conventionally we look from above the North pole and say the Earth rotates anticlockwise (from East to West). If your reference frame was a view above the South Pole then you would say the Earth otated clockwise (from East to West).
