Earth’s Geomagnetic Reversal: Flipping Polarity
The Earth is a big magnet. This is why compasses point to the magnetic north. But north didn’t always point northward because of magnetic pole reversals.
5 Asthenosphere Facts: What is the Asthenosphere?

What Is the Stratosphere?
Main highlights of the stratosphere are: (1) The ozone layer absorbs harmful UV light (2) This causes temperature to rise (3) It contains 10% of air mass.
South American Plate: Tectonic Boundary and Movement

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?
Geophysicists study the physical processes that relate to Earth. For example, they work in seismic, marine and gravity for subsurface investigations.
Coriolis Effect: Air Circulation in the Atmosphere
The Coriolis effect is the deflection of air due to Earth’s rotation. Air veers to the right in the northern hemisphere. And vice versa south of the equator.
