How heavy is North America?
You can use a scale to measure how heavy something is…but what if that something is really big? Like, really, REALLY big? Like the WHOLE continent of North America? There’s no scale big enough, so you gotta use science and math! We asked geoscience grad student Kelsey Woody to help us find the answer. Got a question that’s weighing heavily on you? Send it to us at BrainsOn.org/contact, and we’ll help lighten the load by finding the answer!
