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.
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.
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.
Coral Reef Facts: Ocean Biodiversity Hotspots
Coral reefs are biodiversity hotspots for ocean life. Remarkably, about 1/4 of marine species reside in them. So the spotlight is on coral reefs for protection.
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.
