Hey, i'd like to know what this means:

Tropical monsoon forests are located "between 10° and 25°N and S of the equator".

What does this mean? I know that the 25°N and S of equator means that region near the equator, but what is that "10°"?

There are two regions or latitude bands where the monoson forests may exist:

(1) between 10 and 25 degrees north latitude and (2) between 25 and 10 degrees south latitude. The equator is between these two bamds.

If you understand where 25 degrees north latitude is, you should also understand where 10 degrees north is.

what has been one of the chief obstacles to industrialization in this region?

The statement is referring to the geographical location of tropical monsoon forests. The "10°" mentioned in the statement refers to the latitude. Latitude is a measurement of distance north or south of the equator, and it is measured in degrees. The equator itself has a latitude of 0°.

In this context, "between 10° and 25°N and S of the equator" means that tropical monsoon forests are found in a belt of land that extends from 10 degrees north of the equator to 25 degrees north of the equator, as well as from 10 degrees south of the equator to 25 degrees south of the equator. It includes regions within those latitudes, encompassing a specific range of latitude for the location of these forests.

By specifying these latitude ranges, the statement helps to define the general geographical area where tropical monsoon forests can be found.
