Introduction to Earthquakes Plate Tectonics - Earth Like a Puzzle - Children learn about plate tectonics, earthquakes, and volcanoes at this site in Scripps Institution of Oceanography by Nan Criqui Most people know that Earth is moving around the Sun and that it is constantly spinning.

What I think about when I think about thinking about running · The42 I STARTED RUNNING almost 18 months ago. If you think my next sentence is going to be: ‘So now I’m training for my first half marathon, after doing six 10ks and a handful of 5ks’, well, my friend, you have more faith in me than I do. I’ve racked up a grand total of two 5k races, and my usual runs are between 3k and 5k, depending on how I’m feeling and if I’m on a good running streak. I’m aiming to get to 10k before the end of this year, which, if you read any running blog or chat to any runner, probably seems very conservative for someone who’s been running for this long. But, as I’ve discovered, running really does show you who you are. And yet, somehow I manage to drag myself out for a run. As a novice lazy runner, these are the running truths as I now know them.

Sometimes, you need to appeal to your own vanity to get motivated. Do you run?
