Most of the land on the earth is in the northern hemisphere.
Of the 7 continents, 3 are entirely in the Northern hemisphere and 2 more have significant portions north of the equator.

The only equator is the equator of the Earth, that is, its center line which is half way between the north pole and the south pole. Australia (which means 'south place') is well south of the equator.
The equator is a line that circles the Earth halfway between the North and South Poles. It divides the Earth into the Northern Hemisphere and the Southern Hemisphere.
Half of any sphere is a 'hemisphere'. In the case of the equator, the halves north and south of it are called the Earth's 'northern hemisphere' and 'southern hemisphere'.
The Earth has an equator. The equator goes around the middle of the Earth. The equator is the circular line that goes around the Earth that is half way between the North and South poles. The equator is defined by the Earth's rotation and for that matter so are the locations of the North and South poles. Even without the Sun as a guide, we would know there was an axis of rotation and so we would be able to define the mid-plane perpendicular to that axis half way between the two ends.
The Northern Hemisphere.
Equator
You get the north hemisphere and the south hemisphere.
The equator divides the earth into the north and south hemispheres.

The equator is a line that circles the Earth halfway between the North and South Poles. It divides the Earth into the Northern Hemisphere and the Southern Hemisphere.
Half way would be the Equator (zero latitude).
To the north of the equator is the northern hemisphere, and to the south is the Southern Hemisphere.
A hemisphere is one half of the sphere that makes up Earth's surface.
The Earth is split into two hemispheres based on the Equator. The North Pole is in the Northern Hemisphere. With the South Pole is in the Southern Hemisphere.
The furthest distance from north to south (on the earth) would be the distance from the north pole to the south pole, or half of the earth's polar circumference. It's about 12,400 miles, just a little bit less than half-way around the equator.
Half of any sphere is a 'hemisphere'. In the case of the equator, the halves north and south of it are called the Earth's 'northern hemisphere' and 'southern hemisphere'.
