What is the longest river in the world? Nile? Amazon? Or the Mississippi? What is the deepest trench in the ocean? Which is the largest of America’s Great Lakes? And which river flows through the Grand Canyon?

So how much do you really know about your natural world – rivers, lakes, seas and oceans?

Have a go at answering our carefully selected questions. If you do well, you will have proven how good you are at mastering your world. But if you do poorly, then surely, you should never be allowed to relax on the beautiful sunny beaches of Barbados.

As with all our quizzes, we do not want to bore you with zillions of questions. Instead, each quiz is just 100 questions on a particular topic, packaged in a neat app.

We like to call it the ‘Disposable Quiz’ package.

If you like our quizzes and want to send us your own quiz title plus questions, then visit www.100q-quiz.com or send us an email on support@100q-quiz.com

Thanks

Yours sincerely
