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.
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.
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.
From astrophysicists to arborists, this environmental science salary pyramid gives a sneak peak of how much earth scientists earn in their respective field.
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.
Conservative or transform plate boundaries slide across each other. They neither converge or diverge such as parts of the North American and Pacific Plate.
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.
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.
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.
97% of scientists agree humans are causing global climate change. For example, evidence includes rising sea levels, warming oceans and shrinking ice sheets.
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.
The Cambrian explosion was the largest diversification of life in Earth’s history. Ocean life started as sparse and simple. Then, it remarkably diversified.
The single-most important biochemical reaction human beings need is cellular respiration. Our cells require oxygen to break down the food and provide energy.
The Paleozoic Era marked the first fossil records of animal life.The Cambrian explosion was the largest diversification of life in Earth’s history.
Hydrogeologists are groundwater specialists who focus on how soil and rock relate to groundwater. This includes the transportation of water into the surface.
