Together, these layers protect us from the sun’s harmful radiation and keep temperatures on Earth habitable for all living beings. Understanding how the atmosphere works is crucial to everyday life.

The monumental finding suggests the Earth has five major layers instead of four, and offered new details scientists could use to help unlock some of the oldest mysteries about our planet and how ...

In 1970, Russian geologists drilled a nine-inch wide hole into the Kola Peninsula’s Baltic Shield — a part of Earth’s crust with rock well over a billion years old — and began digging as deep as they ...

Findings uncovered by the researchers, published in Nature Communications, confirmed there are five layers to the earth’s core and not four like has been historically thought.

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.

Researchers on February 21, 2023 said an intensive study of Earth’s deep interior confirmed the existence of a distinct structure inside our planet’s inner core — a wickedly hot innermost ...

Scientists have long wondered what lies at the center of the Earth. New research is putting weight behind a theory that our home planet has a distinct ball of iron within its metallic core.
