Inside Earth

We can’t physically go inside the Earth. But we use seismic tomography from earthquakes to see inside our planet. From Earth tomography, we create 3D models.

Four radioactive isotopes inside Earth account for 50% of its internal heat. Like a slow cooker, they slowly release heat within the planet keeping it warm.

Under the rigid layer of rock we live on, the Earth is plastic & more dense. Because of its fluid properties, mantle convection can occur within the Earth.

The asthenosphere is the unsung hero of our planet. This plasticky layer 80 to 200 km beneath Earth provides the necessary lubrication for plate tectonics.

Earth’s crust is all around us. It’s the layer we live on. But did you know that Earth’s crust is composed of oceanic and continental and oceanic crust?

All planets have layers. Inside Earth, we have a crust, core and mantle. Imagine a team of drillers who set out to drill a hole to the other side of Earth.
