How are cinder cones (volcanoes) formed from a build-up of gases? Explain the term vapor diffusion. Describe the chemistry behind how an instant cold pack works. Explain how a voltaic cell works. Be sure to mention the various parts of the voltaic cell and what they have to do with how...
But here's the twist: While oil and water are the classic examples of liquids that refuse to blend, their densities are quite different. So, for a lava lamp to work its magic, you need two liquids that aren't just hesitant to mingle but also have densities that are nearly identical. T...
How are asteroids formed in space? Were asteroids the cause of impact craters on the moon? How was Meteor Crater discovered? What type of crater is Meteor Crater? Why do asteroids have craters? Which moon of Jupiter is covered in active volcanoes? What is the moon's core made of? What ...
Volcanoes are classified as dormant, active, and extinct. One of the most active volcanoes today is in Mauna Loa, Hawaii. Is it magma or lava? Well, it’s both! Magma is the liquid rock inside the volcano, and once it spills out of it, it is called lava. Lava will burn everything...
(literally), left over from the time when volcanoes hurled it into the atmosphere several billion years ago. By contrast, oxygen (both in O2and O3,or ozone, molecules) and the other elements in air are vital to life. Furthermore, oxygen is one of two elements, along wit...
Volcanoes may be intimidating, but learning how to draw a volcano doesn’t have to be! This guide will be fun and easy for kids of all ages to follow and enjoy. Much like any other kind of natural disaster, there is something awe-inspiring about a volcano eruption. If you can see ...
You can walk through at your own pace and will take you anywhere between 30 and 90 minutes but you get an insight into the Galapagos Islands, yes ALL of it: How they were formed, where the volcanoes are, the differences between the famous Darwin finches (fun fact, he didn’t study the...
and air travel has become a core part of the process. Since mass air travel became a possibility, little stopped our appetite for it. When OAG analysts tracked the impact of major global events such as 9/11, SARS outbreak, the eruption of volcanoes, global recession, etc., which temporaril...
Andes:Formed by the subduction of the Nazca plate beneath the South American plate, the Andes are a volcanic range with active volcanoes along the subduction zone. Appalachians:An older range in North America, formed about 480 million years ago, the Appalachian mountains display a folded structure...
