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.
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.
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.
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.
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.
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.
Paleozoic Era: Diversification of Life (540 to 252 million years ago)
The Paleozoic Era marked the first fossil records of animal life.The Cambrian explosion was the largest diversification of life in Earth’s history.
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.
3 Types of Volcanoes: Stratovolcano, Shield and Cinder Cone
The 3 types of volcanoes are stratovolcanoes, shield volcanoes and cinder cones. Based on their geography, volcanoes take different appearances.
Pacific Plate: Movement and Direction of the Pacific Tectonic Boundary
The Pacific Plate stretches all the way along the west coast of North America and reaches all the way to the east coast of the islands of Japan & Indonesia.
How Volcanoes Form Igneous Rocks
Volcanoes are the foundation for igneous rocks. When volcanoes erupt, magma and lava spews out. After cooling and solidifying, they become igneous rocks.
Convergent Plate Boundaries: The Collision of Plate Tectonics
Convergent plate boundaries have some of the most violent catastrophes and geology on Earth. When plates smash together, it has created chains of volcanoes.
Hadean Eon: The Formation of Earth (4.6 to 4.0 billion years ago)
4,567,000,000 years ago, Earth was covered in molten lava. In the Hadean Eon, it was in its earliest stage of formation as it clumped from a cloud of dust.
Soil Nutrients Deficiency and Replenishing
Plants mostly use water and carbon dioxide from the air to grow. But nutrients like nitrogen (N), phosphorus (P) & potassium (K) are also key ingredients.
