I need to learn about Zambia, please.
Zambia is a landlocked country in south0central Africa. From 1972 to 1991, Zambia was a one-party state with the UNIP as the sole legal political party under the motto "One Zambia, One Nation".
Oh wow! What do you know about the geography and geology there?
Zambia has a tropical climate and consists mostly of high plateaus with some hills and mountains, dissected by river valleys. From Luangwa town, the Zambezi leaves Zambia and flows into the Mozambique channel.
Oh that sounds beautiful. Do they have massive mountains there?
Hills and mountains are found by the side of the valley, notably in its north-east the Nyinka Plateau(2200 m) on the Malawi border, which extend into Zambia as the Mafinga Hills containing the country's highest point, Mafinga central.
Oh any idea how high the highest point is?
Zambia is located on the plateau of Central Africa, between 1000-1600m above sea level.
Oh cool. I've learned enough about the geography. What can you tell me about etymology?
The name Zambia, derives from "Zambezi" which can be translated to "grand river"
Oh that's interesting. Anything else about etymology?
No, would you like to know more about the geography and geology?
No worries, you've taught me a lot. Thanks!
Goodbye.
