Everything that happens on our planet above the ground is taking place in Earth’s protective envelope called the atmosphere. While more than 6,000 miles thick, the atmosphere is comprised of five distinct layers. Each layer has unique characteristics. In between these layers are boundaries called...
In the exosphere, the atmosphere becomes exceedingly thin, with gas molecules spread out over vast distances. Unlike the denser layers of the atmosphere closer to Earth, the exosphere contains very few particles, primarily lightweight gases such as hydrogen and helium. These particles are so sparse...
EarthGeochemistryIn the last twenty years modern chemical and physical methods have done much to extend our knowledge of the Earth. Some new questions have been raised, e.g. the question of the bonding relationships in the Earth's interior, which make the Earth an interesting object of ...
Geophysics is the study of what's inside the Earth. Scientists study surface rocks, observe the planet's movements and analyze its magnetic fields, gravity and internal heat flow, all to learn more about the planet's interior. The Earth is made up of dis

What are the physical features of the sunlight zone? Which layer creates the Earth's magnetic field? Which layer of the Earth contains magma? Which layer of the Earth contains the crust? In what layer of the Earth's interior do primary waves travel the fastest?
However, advances in seismology have allowed us to learn a great deal about the Earth and the many layers that make it up. Each layer has its own properties, composition, and characteristics that affects many of the key processes of our planet. They are, in order from the exterior to the...
