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 is Permafrost? Why It’s Like the Glue for Rock and Soil

Think of permafrost like glue. The ice is the glue in permafrost which holds the rocks, sand & soil. Like glue, permafrost doesn’t melt. Instead, it thaws.

What Causes Tsunamis? A Guide to How Tsunamis Form

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?

How Fast Does the Earth Spin? Earth vs The Engineered

How fast does the Earth spin? Earth spins at an incredible 1000 miles per hour (1600 km/hr). We compare the Earth’s spin to nature and engineered velocities

Pangea Ultima: Meet Earth’s Next Supercontinent

If you could fast-forward 250 million years in the future, you would witness all continents will assemble into one giant supercontinent called Pangea Ultima.

Moon Gravity: Your Weight on the Moon

The gravity of the moon is 1/6 of Earth. If you stepped on a scale on the moon, you could subtract 83.5%. So 100 kg in weight would be 16.5 kg on the moon.

Supermassive Black Holes: The Center of Galaxies [Infographic]

All galaxies have supermassive black holes at the center of it. These collapsed stars are a few times the mass of a sun which run out of fuel and explode.

What Are the 5 Koppen Climate Classification Types?

The Koppen climate classification catalogs Earth’s types of environments, which include 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.

13 Parts of a Volcano: The Anatomy of Volcanoes

Today, we explore 13 parts of a volcano. From tephra, fumaroles, magma, lava domes, pyroclastic flow to volcanic bombs, this is the anatomy of volcanoes.

Solar Radiation: How Sunlight Heats the Planet

Our sun is 99% of the total mass of the solar system. It’s this energy from the sun’s thermonuclear reactions that heats the Earth from solar radiation.

Transform Plate Boundaries: Sliding Plate Tectonics

Conservative or transform plate boundaries slide across each other. They neither converge or diverge such as parts of the North American and Pacific Plate.

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.
