El Niño vs. La Niña: What’s the Difference?
El Niño is the warming phase of the waters in the eastern Pacific. Then, La Niña is the cooling phase. Both phases disrupt weather patterns around the globe.
What Is the Troposphere?
The troposphere is the lowest layer of the atmosphere. It starts at ground level and extends upwards to about 13 km. All weather occurs in the troposphere.
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.
10 Unbelievable Weather and Climate Facts
Weather patterns have tremendous impacts on people and ecosystems on Earth. Let’s get started with this list of 10 unbelievable climate and weather facts.
How the Greenhouse Effect Traps Heat and Warms Earth
Because greenhouse gases trap heat in the atmosphere, this helps regulate temperature on Earth. Without the greenhouse effect, we’d live in an icebox.
5 Major Air Pollution Sources in the Atmosphere
Whether it’s agriculture, industry, vehicles, electricity or natural disasters, these are the major air pollution sources that contribute to climate change.
What Are the 5 Koppen Climate Classification Types?
The Koppen climate classification catalogues Earth’s types of environments. In the eyes of Koppen, they are tropical, dry, temperate, continental and polar.
Taxonomic Classification: From Domain to Species
In biology, we categorize life by how similar organisms are with each other. Like a family tree, we find relationships by their classification of life.
What Are the 3 Domains of Life?
We categorize life into 3 domains of life: eukarya, archaea and bacteria. Domains classify life in the most general way such as the presence of a nucleus.
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.
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.

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 Do Agronomists Do?
Agronomists focus on crop production and applying new technologies. An agronomist studies plant science to improve efficiency in crop production.

Lahar: Flowing Mud at Volcanoes
“Lahar” is an Indonesian word for mudflow at volcanoes. Lahar flows down volcanoes as a mix of mostly water, mud and rock debris (similar to wet concrete).
Inside Earth: The Crust, Mantle and Core
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.
What is a Stratovolcano (Composite Cone)?
The stratovolcano is tall, steep & cone-shaped. Unlike shield volcanoes, stratovolcanoes build up height by layering lava, ash and tephra on top of another.
3 Types of Faults: Normal, Reverse and Strike-Slip
The 3 types of faults are: normal, reverse and strike-slip. When two blocks slide horizontally, it’s strike-slip. If it moves vertically, it’s dip-slip.
What’s the Difference Between Meteors, Meteorites and Meteoroids?
Their difference is location. Meteoroids are up in the sky. Meteors fall to Earth and flash light breaking down in the atmosphere. Meteorites are on Earth.
Facts About Asteroids and Our Asteroid Belt
Asteroids are odd-shaped rocks made of metal and other elements. There are about 100,000 known asteroids mostly in the asteroid belt between Mars & Jupiter.

Tsunamis are long, tall waves that can be disastrous to anything nearby. But what causes tsunamis? 80% start from earthquakes. And how do tsunamis form?
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.
