Earth Is Big: A Book Of Comparisons by Stephen M. Tomecek, illustrated by Marcos Farina

Publication Date: 2 September 2021

The Blurb

Find out how unique Planet Earth really is in this eye-catching book of comparisons!

Earth is big! (compared to a frog). Earth is small! (when it’s hiding in a galaxy). And that’s not all. Earth is wet and dry, hot and cold, round and jagged, fast and slow. You get the idea. It depends how you look at it!

Get to know our planet in a whole new way by comparing it to a huge variety of other incredible things – from tiny particles to giant star clusters. Did you know soap bubbles are some of the roundest objects in the universe? Or that we humans are totally outnumbered by chickens? Or that the driest desert on Earth isn’t scorching but freezing? Tour some of the most extreme places on the planet and beyond it, take a look at life forms from bacteria to elephants to redwood trees and explore what makes our planet the perfect home for us.

You’ll never see Earth the same way again!

The Review

A contradictory cornucopia of facts about planet Earth, perfect for exploring our world from differing perspectives.

The captivating spreads are stunningly illustrated, helping to visualise the mind blowing facts with a range of infographic styles. I love that each spread has its opposite to challenge thinking further, so while Earth is big, cold, round and heavy, we also find out how it is small, hot, jagged and light, and that it questions whether Earth is really ours…

With a glossary, index and source notes at the end, this is brilliant for introducing younger readers to reference books and being able to send them off exploring further, should the whim take them.

A must for Key Stage 2 classrooms to dip in and out of for a whole range of different geography and science topics, and the perfect non-fiction pleasure browser to capture inquisitive minds and imaginations.

The Guest Post

What inspired me to write this book and how was it developed?  

As a scientist I’ve always been excited by new discoveries and understanding how the universe works. If you stop and think about it, science is more than a collection of facts. It’s a process of discovery where one generation of scientists build on the work of those that came before. When I write a book, I want to get this idea across and show how modern-day scientists use new technologies to refine old ideas and take them to the next level. A big part of science is measurement… Scientists are always working to gather data on how big, how far, how fast, and how old things are. Over the years we’ve collected a great deal of data about our Earth and the things found on it, and I wanted to share this information in a fun, engaging way. 

When I was a kid, I took a lot of road trips in the car with my parents and unlike today there was no satellite radio or video entertainment systems. To pass the time, we played a game called “20 Questions”.  In this game, players guess the identity of a “mystery object” that another player is thinking about by asking simple questions. The questions often took the form of a comparison such as  “is it bigger than a car” or “is it heavier than a brick”? This got me thinking about how our Earth compares to other things found in our universe and how cool it would be to put all that information together in one big book.  

We know the Earth is Big, but just how big is it? How does it compare to the tiniest atoms, or the super massive stars found in the far off reaches of our galaxy? In order to sort it all out, I started looking at some of the important properties of our planet. Characteristics such as its size, shape, age, how heavy it is, how wet it is, how hot it is and how fast it is moving through space. Then I did a ton of research to get the most current and accurate information and triple checked the sources before including the data in the book.  Along the way I discovered some unbelievable facts about our planet. For example, did you know that the driest place on Earth is not one of the burning hot deserts found near the equator. It’s actually freezing cold and is found in the dry valleys of Antarctica where it hasn’t rained in over 2 million years!  Another cool fact is that compared to Venus, our Earth is really cool. While our average surface temperature is around 15 degrees Celsius, the average surface temperature of Venus is over 450 degrees Celsius!
