Astronomers spot two stars the size of Earth headed toward a violent explosion - This discovery offers a glimpse into the ...

The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball ...

By the time of the moon-forming impact, the Earth was already separated into these rock and metal layers. However, the intense force and heat of the impact re-melted the proto-Earth, re-mixing the ...

Scientists have always been curious about the atmosphere surrounding us, but in the past, they could not just hop on a spaceship to see what was up there. Instead, scientists hiked up high ...

The Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents, evidence suggests it is the plates that drive the convection. Slab pull ...

Over time, Earth's interior—which is made mostly of silicate rocks and metals—differentiated into four layers. At the planet's heart lies the inner core, a solid sphere of iron and nickel that ...

The End-Permian mass extinction killed an estimated 80% of life on Earth, but new research suggests that plants might have done okay.

Led by Curtin University geologists Chris Kirkland and Tim Johnson, a research team unearthed this primeval crater beneath rock layers in the East Pilbara Terrane of Western Australia. The oldest ...

The Earth has a layered structure made up of the core, the mantle and the crust. Different elements are present in different parts of the Earth’s structure. The crust is made from enormous ...

Sometimes the “whys” of history are lost, and that holds true to why Capt. John Cleves Symmes Jr. wholeheartedly believed the Earth was hollow.
