Earth’s layered structure. The right side of the large cross section shows that Earth’s interior is divided into three different layers based on compositional differences—the crust, mantle, and core. The left side of the large cross section depicts layers of Earth’s interior based on physic...
The discovery marks a significant turning point in our understanding of the Earth's interior, revealing the inner core to be far more complex and dynamic than previously thought. As scientists continue to explore the mysteries of our planet's depths, it becomes increasingly clear that there is s...

Seismological studies have previously detected abundant scatterers in the lower mantle, potentially linked to long-term slab subduction, and petrology studies suggest carbonates can be sequestrated within the oceanic crust and transported into the lower
Explanation of how objects under the influence of gravity move in orbits. Video: Encyclopædia Britannica, Inc. Explore planet Earth's interior structure; the crust, the mantle, and the core Earth is composed of three layers: the crust, the mantle, and the core. Video: Created and produ...
Gap models have been implemented in numerous forest biomes worldwide at the stand scale (Shugart et al., 2018, 2020) and also spatially distributed across large regions including the Amazon basin (Rödig et al., 2017), Russia (Shuman et al., 2017), and interior Alaska (Foster et al.,...
The interior of the Earth consists of several layers. The outermost layer, upon which we live, is the crust. It's the thinnest layer. Below the crust is the mantle. The mantle is the largest layer. Below the mantle are the outer and inner cores....
One of these slabs currently straddles the boundary between the mantle transition zone and the lower mantle roughly 410 miles (660 km) beneath the Midwest. Dubbed the "Farallon slab" and first imaged in the 1990s, this piece of oceanic crust is responsible for a process known as "cratonic ...
Also in the 1960s, mankind successfully broke away from the gravity of Earth and set foot on the Moon. The research on global change that began in the 1980s extended the study of the human living environment to span the entire Earth system, combining the study of Earth's interior with ...
One of the paradoxes of the Archean rock record is how evidence for oxidative continental weathering is plausible when the atmosphere lacked oxygen prior to the Great Oxidation Event ca. 2.5 billion years ago. We detected reactive oxygen species (ROS) pr
