Earth Tomography: How Seismic Waves Travel 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.

97% of scientists agree humans are causing global climate change. For example, evidence includes rising sea levels, warming oceans and shrinking ice sheets.
Coral reefs are biodiversity hotspots for ocean life. Remarkably, about 1/4 of marine species reside in them. So the spotlight is on coral reefs for protection.
The Cambrian explosion was the largest diversification of life in Earth’s history. Ocean life started as sparse and simple. Then, it remarkably diversified.
The single-most important biochemical reaction human beings need is cellular respiration. Our cells require oxygen to break down the food and provide energy.
The Paleozoic Era marked the first fossil records of animal life.The Cambrian explosion was the largest diversification of life in Earth’s history.
Hydrogeologists are groundwater specialists who focus on how soil and rock relate to groundwater. This includes the transportation of water into the surface.
All living things rely on each other in the food chain. Energy transfers through living organisms from predators, herbivores, producers and decomposers.
Agronomists focus on crop production and applying new technologies. An agronomist studies plant science to improve efficiency in crop production.
The biosphere is the layer of Earth where life exists. You, me, plants, insects bacteria and all living things on land, air and oceans are the biosphere.
The pedosphere is like the “skin of Earth”. Just like your skin, it has a thin outer surface. It also has pore spaces and dries out without enough moisture.
The 3 types of volcanoes are stratovolcanoes, shield volcanoes and cinder cones. Based on their geography, volcanoes take different appearances.
Earth scientists need all the *sciences* to understand how the Earth works. This list of 113 branches of Earth Science is the most in-depth you’ll ever find
The Pacific Plate stretches all the way along the west coast of North America and reaches all the way to the east coast of the islands of Japan & Indonesia.
If you stick a pencil through Earth at the point of rotation, these 2 points are the north/south poles. Geographically, it’s where longitude lines converge.
