Every two years, the National Science Foundation releases a report on the state of science in the U.S. and around the world. It includes survey data for how Americans answer basic scientific questions such as "Does the Earth go around the Sun, or does the Sun go around the Earth?" and "True or false: electrons are smaller than atoms." The results of the most recent survey, conducted in 2012 with more than 2,200 adults, have just been released.

Here's a list of the questions in the survey, along with their correct answers. Below each question, you'll see a graph showing the percentage of Americans who gave the correct answer, along with the percentage of people in other regions who answered correctly when asked similar questions.

As you'll see, in the words of the report, "many Americans provide multiple incorrect answers to basic questions about scientific facts." Then again, "residents of other countries, including highly developed ones, appear to perform no better."

1. The center of the earth is very hot

Correct answer: True

2. The continents have been moving their location for millions of years and will continue to move
