New research suggests that Earth's first crust, formed over 4.5 billion years ago, already carried the chemical traits we ...
The study also provides a new approach to solving one of the biggest enduring scientific mysteries: when did plate tectonics ...
Earth’s earliest crust, formed over 4.5 billion years ago, has long been thought to have lacked the complex chemical features ...
New crust is continually being pushed away from divergent boundaries (where sea-floor spreading occurs), increasing Earth's surface. But the Earth isn't getting any bigger. What happens, then, to ...
It’s long been thought that tectonic plates needed to dive beneath each other to create the chemical fingerprint we see in ...
Modern continental rocks carry chemical signatures from the very start of our planet's history, challenging current theories about plate tectonics.
The diagram below shows the structure of the earth. In geography, taking a slice through a structure to see inside is called a cross section. Continental plates are usually quite thick (between 35 ...
Scientists have long thought that tectonic plates needed to dive beneath each other to create the chemical fingerprint we see in continents. Researchers discover Earth's first crust, formed 4.5 ...
Gather your supplies! In this episode we will use everyday materials to learn about tectonic plates and fault lines.
Intraplate volcanism, or volcanism occurring away from plate boundaries, can provide clues about which areas of the MTZ are the most hydrated.
