the economics would be low.
every thing would weigh half its normal weight
allways one half of earth only will get sunlight
If an impact caused the earth to stop rotating it would have already caused damage. For example: If a meteor hit the earth it would crack the earth into pieces, therefore we would be frozen in the darkness for half a year and toasted from the sun the other half.
Earth will be a little colder on parts
All other things being equal then we would not have seasons. That would be the most obvious result.
half of the world would be homeless.
Every single life on earth will be destroyed in an instant and the earth core/all the lava will probably pour out. Other wise the earth might explode a big chunks of earth will hit other planets :~[]lol
The equator splits up half of the earth. The equator is a line that splits half of the earth
If a candy bar was cut in half the mass would decrease.
Half way would be the Equator (zero latitude).
How would the earth travel around the earth?
Hopefully, this is a thought experiment! It is gravitational attraction that keeps objects "stuck" to the Earth, so if the Earth split into half, you would still be attracted to it - although by half as much (as the mass of the Earth would have been halved). So you still couldn't fall off.
