The earth is formed of layers. The surface of the earth, about 200 kilometers thick, is made of large pieces. When they move against each other, an earthquake happens. A large movement causes a violent earthquake, but a small movement causes a mild one. Earthquakes last only a few ...
Earth's atmosphere is more than 6,000 miles thick, and is made up of five distinct layers. 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 ...
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
Layers of the Atmosphere The Earth’s atmosphere has five main layers and a sixth layer, the ionosphere, that overlaps the mesosphere, thermosphere, and exosphere. The five vertical layers of the atmosphere are: Troposphere Stratosphere Mesosphere ...

s deep interior, to determine what Earth’s layers looks like. In addition, it is understood that the differences in temperature and pressure are due to leftover heat from the planet’s initial formation, the decay of radioactive elements, and the freezing of the inner core due to intense ...
Earth science concentrates on investigating how the planet works and why. This field delves into the many layers of the Earth and explains how those pieces fit together into a cohesive structure. The interdisciplinary subject not only provides insight into the mechanics of the solid parts of the ...
