100 Earth Facts: The Big List of Facts About Earth
Earth needs no introduction. From its origin to its inevitable future, the story of Earth is greatest story ever told. Get started with this list of 100 Earth facts.
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.
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.
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.
4 Food Chain Levels: Predators, Herbivores, Producers and Decomposers
All living things rely on each other in the food chain. Energy transfers through living organisms from predators, herbivores, producers and decomposers.
What Do Agronomists Do?
Agronomists focus on crop production and applying new technologies. An agronomist studies plant science to improve efficiency in crop production.
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.
Where is the South Pole?
If you stick a pencil through Earth at the point of rotation, these 2 points are the north/south poles. Geographically, it’s where longitude lines converge.
Ocean Exploration: 20% Explored, 80% Unexplored
We’ve mapped 100% of oceans at 5 km resolution using satellite radar. We’ve mapped 20% with bathymetry sonar. But nearly 80% of oceans have gone unexplored.
33 Branches of Biology: A Comprehensive Outline
What are the branches of biology? Biology studies living things, flora and fauna. We categorize biology into botany, toxicology, ecosystem and chronology.
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.
Marine Biologist Career: What Do Marine Biologists Do?
Marine biologists specialize in how life in the oceans behave. They collect ocean samples, record fish distributions and conserve aquatic life in habitats.
