A hemisphere is one half of the sphere that makes up Earth's surface.
How would the earth travel around the earth?
The Earth has day and night every 24 hours because that is the total amount of time it takes to spin on its axis. When one half faces the sun, it is day in that area of the globe, while it is night in the other half.
No. Gravity would no longer be acting on you perpendicular to the earth's surface due to the Earth being only half a sphere, assuming the other half somehow vanished. As you approached the edge you would be pulled at a greater angle back towards the center of mass making the approach to the edge seem like an ever increasing upward slope, until you got over it and it would seem to be a downward slope, where you could presumably tumble until you reached the center. Joy.
Hemisphere.
Approximately : land plants have been around for a half a billion years. The Earth for 4.5 billion years. So your answer is one ninth.
A half of the Earth that is cut longitudinally is referred to as a hemisphere.
One half of the earth is a hemisphere. There is a northern, southern, eastern, and western hemisphere.

Equator!!
the northern hemisphere the other half the south hemisphere
the northern hemisphere the other half the south hemisphere

The likely word is "hemisphere" (one half of a sphere, one half of the Earth's surface).
