How the ROCK CYCLE Recycles Earth’s Crust
The rock cycle recycles the crust If you could speed up time, you would see rocks continuously cycling from the surface down into the deep interior of the planet and back up again. Like a […]

ASTHENOSPHERE: 5 Things to Know
1 The lithosphere rides on the asthenosphere The asthenosphere is the unsung hero of our planet. This plasticky layer 80 to 200 km beneath our feet provides the necessary lubrication for plate tectonics. That’s right. […]

RADIOACTIVE DECAY: Four Isotopes Put Earth on a Light Simmer
Radioactive isotopes puts Earth on a light simmer Four radioactive isotopes inside Earth account for about 50% of Earth’s internal heat. Like a slow cooker, they constantly release heat within the planet keeping it on […]

EARTH TOMOGRAPHY: How Seismic Waves Travel Inside Earth
We use earthquakes to peak into Earth We can’t physically go inside the Earth. But we use imaging and seismic tomography from earthquakes to see inside our planet. During an earthquake, a break occurs at […]

The 5 SOIL FORMATION FACTORS: The Weathering of Rocks Into Dirt
Soil formation is vital for food production and plant growth. Weathering is the process that breaks rock down into soils. Without it, soil wouldn’t exist. […]

Is VAALBARA Earth’s First Supercontinent?
The evidence that Vaalbara (2.7-3.6 billion years ago) was the first supercontinent is mainly based on their sedimentary sequences and magnetic orientation. […]

BANDED IRON FORMATION (BIF): Rusted Iron From the Archean Eon
Long ago, oxygen filled the oceans. It mixed with iron which reacted by rusting. The seafloor collected rusted iron called banded iron formation (BIF). […]

PANGEA FOSSILS: Evidence of the Pangaea Supercontinent
At one point in time, all continents were merged together as one supercontinent “Pangea”. We’ve used fossil evidence to know continental drift exists. […]

PACIFIC RING OF FIRE: Volcanoes, Earthquakes and Plate Tectonics
The Pacific Ring of Fire has the most active chains of volcanoes in the world. This is because tectonic plates collide and sink at these zones of subduction. […]
