Blog > Monthly Geo Trivia questions

Hi everyone,

welcome to November 2021 #fridaygeotrivia!

As is our tradition, on the final Friday of month on twitter under the hashtag #fridaygeotrivia we run a geotrivia contest. Afterwards we post the answers here on the blog. See below for how to play.

The November 2021 geotrivia question:

Last month we asked about multi-national rivers, and this month we’re staying with the water theme. This month we ask you to name countries that share one or more “large” transboundary lakes. An obvious example is the United States (US) and Canada (CA). The border between the two crosses numerous very large lakes like Lake Superior, Lake Huron, Lake Ontario (all part of “The Great Lakes”).

But what qualifies as “large”? That’s obviously a subjective term, but for our purposes the lake must be at least 25km long. So while the border between the UK and Ireland crosses several lakes, we would not count them as “large”.

To get full points you need to name the countries with emoji flags, the lake(s) and the #fridaygeotrivia hash tag.

Prizes

#fridaygeotrivia is a game with two prizes:

  1. the sheer joy of geographic knowledge and pedantry.

  2. the bragging rights of getting the answer first.

How to play

Anyone can join in, you just need a twitter account. Please note - these edition of the game was played long ago - these days we play on Mastodon, not twitter.

  • Reply to the question thread on twitter (embedded below) using the hashtag #fridaygeotrivia in your answer.

  • Only one answer per tweet

  • While you can use a map, please do NOT use the internet to just search for an answer. That is cheating and will lead to seriously bad geokarma.

  • To get full points for an answer it is good form not just to name the relevant country but (if possible) to include the emoji flags of the country.

Some people have complained the format is a bit chaotic and hard to follow. Yes, the mad chaos is part of the fun. Embrace it. The goal is just to have fun and learn. We win by playing

Happy geocoding,

Ed
