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.
Geology
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.
Mass Extinctions: The 5 Biggest Dying Events in History
Earth has witnessed 5 mass extinctions where life experienced an abrupt ending. Time and time again, nature has always found a way to reshuffle the deck.
5 Soil Formation Factors: How Rocks Weather into Dirt
Soil formation is vital for food production and plant growth. Weathering is the process that breaks rock down into soils. Without it, soil wouldn’t exist.
Human Timeline: How Long Have Humans Existed?
The earliest anatomically modern human fossil found was dated at about 200-300,000 years old in Morocco, Africa. They had modern faces and used stone tools.
Biological Weathering: How Living Things Break Down Rocks
Biological weathering can occur from mechanical force and chemical reactions such as through plants, bacteria, fungi, burrowing animals and living organisms
