The Himalayas

     New Zealand was a blast! The landscape was gorgeous, and once all the research in predicting the next big earthquake was finished, my parents and I got a week to ourselves. We went white water rafting, hiking, went to shows, and did a lot of other fun stuff. I'm sad to have left NZ, but I'm sure Nepal will have some equally  fascinating things in store. We've only been here a day and mom and dad are already hard at work. They've allowed me to stay in the hotel (which is not nearly as nice) just for today to sleep and acclimatize, but I'm ready to get back out there. My parents are now at a research facility in Kathmandu, touching base with the rest of the research team.  They're examining the data collected by machines on Everest placed by climbers as they made their way to the summit. I find this highly impressive, given that I'm lightheaded at an altitude that would make Everest, which is 29,029 feet above sea level, laugh.
    Everest is a pretty amazing land formation, and its kind of hard to be believe that it and the rest of the Himalayas exists all because of plate tectonics. Mom and dad have been going on and on about since we got here. Supposedly these two continental plates, the Indo-Australian and Eurasian Plates, collided, and as the Indian subcontinent slammed into the Eurasian continent, the Himalayas were formed. This sort of boundary is called a collision boundary, and often results in earthquakes and mountain ranges. They aren't however known for volcanic activity as no magma is forcing its way up, nor is the mantle heating a subducting plate to make magma. If your looking to find them on a map they are at 27°59′17″N 86°55′31″E.  Now these two land masses are wedged together and continue to push and grow taller (About 5 mm a year), causing earthquakes from time to time. India continues to drive into China at around 5 centimeters a year. This picture gives you a good idea of what happened to cause these amazing mountains.

As you can see, India made its way over millions of years before slamming into Eurasia.

Also, here's a diagram of a collision boundary:
