Answer:

>>> Geography

Rainfall in an area is influenced by various factors, including geographical location, topography, wind, and other factors. There are several factors that can explain why rainfall on Sumatra Island tends to be higher than that on Nusa Tenggara:

• Number 1

Geographical Location: Sumatra Island is located west of Indonesia and closer to the equator, so the temperature tends to be higher compared to Nusa Tenggara which is located to the east. Higher temperatures can increase water evaporation in the sea and trigger the formation of rain clouds.

• Number 2

Topography: The island of Sumatra has high mountains on its western side, such as the Bukit Barisan Mountains, while Nusa Tenggara is relatively flat. The undulating topography with lots of mountains can affect air movement and trigger the formation of rain clouds.

• Number 3

Wind: Sumatra Island is located in the path of westerly winds that carry moisture from the Indian Ocean. While Nusa Tenggara is located in the southeastern part of Indonesia, so the wind does not carry much moisture from the sea.

Explain: The combination of these factors can explain why rainfall on Sumatra Island tends to be higher than Nusa Tenggara. However, keep in mind that rainfall in each area can vary over time and can be influenced by many other factors.
