It slooowwwwssss down... the colder the slower.
Natural, it is not man made.
H=88 G=92 K=91 M=89
How you solve this is G is the same thing as 92 because it crosses each other same thing with K. Then after that you just subtract 180 by 92 to get H because the line angle equals to 180 same thing with M
C - North to South
The Mekong, Irrawaddy, and Chao Phraya rivers all flow from North to South, thus answering your question.
Hope this helps!
