Main Sequence Star: Our Sun’s Thermonuclear Reaction
Our sun is a main sequence star. This just means that it burns hydrogen into helium and goes through this “main sequence” for about 95% of its life span.
Ocean Salinity: How Much Salt is in Oceans?
Oceans are salty because runoff transports minerals and salts from the surface. When ocean evaporates from heat, salt remains in the ocean and water rises.
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.
The Impacts and Effects of Climate Change
97% of scientists agree humans are causing global climate change. For example, evidence includes rising sea levels, warming oceans and shrinking ice sheets.
Coral Reef Facts: Ocean Biodiversity Hotspots
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.
Cambrian Explosion: Life Diversification in the Oceans
The Cambrian explosion was the largest diversification of life in Earth’s history. Ocean life started as sparse and simple. Then, it remarkably diversified.
Cellular Respiration Steps: Energy Conversion in the Body
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.
Hydrogeology Careers: What Do Hydrogeologists Do?
Hydrogeologists are groundwater specialists who focus on how soil and rock relate to groundwater. This includes the transportation of water into the surface.
What Are the 4 Levels of the Food Chain?
All living things rely on each other in the food chain. Energy transfers through living organisms from predators, herbivores, producers and decomposers.
What Do Agronomists Do?
Agronomists focus on crop production and applying new technologies. An agronomist studies plant science to improve efficiency in crop production.
The Biosphere: Life on Earth
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: Soil on Earth
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.
