Answer:

1. Latitude. Kuala Lumpur is located in the equatorial zone, near the equator, so it receives a lot of sun for the  entire year, and this explains its warm climate.

2. The main reason for this difference is the altitude: while Minsk is located at 280 meters over the sea level, Banff is located at approximately 1400 meters over the sea level. As the altitude is higher, the average temperature is lower.

3. Jakarta: in fact, it is located at a similar altitude of Kuala Lumpur (just in the opposite hemisphere), in the equatorial zone, while Baltimore is located much more north, so in a colder region.

4. Because they are located at approximately same latitude (just in the opposite hemisphere), so they are more or less same distance from the equator, and they receive more or less same amount of sun light, therefore they have similar climate.
