Perilous places

"Both the ocean floor and the moon are dangerous places. The water pressure deep underwater is 1,000 times greater than the pressure at sea level. On the moon, humans can't survive without a spacesuit and provisions. How could you choose between visiting these places? Throughout this book, readers weigh their options of visiting perilous places such as the Mariana Trench and risky events such as running with the bulls. Exciting facts about each option are presented alongside full-color photographs, highlighting the thrill of each. Readers use decision-making skills to choose--only to find another tough choice on the next page!"--From the publisher's web site.
