Troposphere: This is the lowest layer of Earth’s atmosphere. The bottom of the troposphere is at Earth’s surface, and it extends up about 6.2 miles (or 33,000 feet).

This layer, consisting of the closest few kilometers of atmosphere to our surface (and over 80% of the Earth's atmosphere, by mass), has shown an increase in ozone density.

The entire outermost part of Earth is able to wander over the rest of the planet, and now researchers say in a new study detailed in the Nov. 8 issue of the journal Nature that they can explain ...

This lowest layer contains more than 80 percent of the massof the atmosphere and almost all of the water vapor, clouds, and precipitation. Several dark cloud layers are visible within this layer ...

The ozone layer is a part of Earth’s atmosphere that captures some of the Sun’s ultraviolet (UV) light emissions. When the ozone layer is compromised, its ability to absorb radiation weakens ...

One of geology's basic principles is that the Earth is made up of four layers: the crust, the mantle, the outer core, and the inner core. But this may be squashed in light of a new study that suggests ...

Earth's outer layers can wander over its core, which causes so-called true polar wander. A model has figured out how Earth's bulge may cause the layers to snap back into place.

This underground water reservoir was identified through the study of seismic waves—the shockwaves created by earthquakes and tremors that travel through the Earth’s layers.

A mysterious layer lies beneath Earth's massive tectonic plates. Sandwiched between two rock layers — the rigid lithosphere and the more pliable asthenosphere— this thin boundary is like the ...

Planet Earth's inner core may have stopped turning and could go into reverse, according to a study published this week. Earth is formed of three layers: the crust, the mantle, and the core.. Made ...

In high school science class, textbooks often feature a recognizable image of the Earth and all its layers—currently, that’s the crust, outer and inner mantle, and outer and inner core.
