Carbon Dating: How Radioactive Isotopes Estimate Age
All life contains types of carbon. When an organism dies, carbon dating examines the ratio between carbon-14 (C14) and carbon-12 (C12) to estimate age.

Photosynthesis Process: Carbon Dioxide to Glucose
The main idea of photosynthesis is it takes carbon dioxide from the air. Then, it uses carbon with water to convert it into a chemical form like glucose
Why Does the Earth Hum?
Seismometers always record periodic noise. Once mysterious in nature, we attribute Earth hum to ocean waves crashing into continents, vibrating like a bell.

How Trees Grow from Carbon Dioxide and Water
For the most part, trees growth is from carbon dioxide and rain water. So most of the dry mass of trees is made from the contents of the air and water.
What Is a Geophysicist?
