Away
because the earth is half facing the sun half facing away it is usually warm
The half of the Earth facing the sun is considered the light side, while the half facing away is in darkness. This creates day and night as the Earth rotates on its axis.
Darkness. Night time
i think 50% because the other 50 % is facing the sun
It happens because the Earth rotates. So at any time, half of the Earth is facing the Sun, so it is bright and day time there and the other half is facing away from the Sun so it is dark and night time. As the Earth continues to rotate, parts that were facing the Sun are soon facing away from it and the parts facing away from it are now facing it, so everywhere gets day and night.
the lighted half is facing towards the sun not the earth
Yes.
There is no such thing as half of the Earth. If you are referring to half of the spherical shape of the Earth then it will be a hemisphere.
The question as asked is meaningless. Perhaps you mean "Where is half the Earth when it is facing away from the Sun?" In that case the answer would be "in darkness or, as we like to call it, night"
It is night in the hemisphere facing away from the Sun.
Because the half of the Earth facing the sun is experiencing day and the other half, that's facing away from the sun, is in the dark. The Sun is Earth's source of light and heat. (which is also why night is colder)
