![SUPERMASSIVE BLACK HOLES: The Center of Galaxies [Infographic]](https://earthhow.com/wp-content/uploads/2019/02/Supermassive-Black-Holes-326x245.png)
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.

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.

From astrophysicists to arborists, this environmental science salary pyramid gives a sneak peak of how much earth scientists earn in their respective field.
From large to small, the 7 major tectonic plates include the Pacific, North American, Eurasian, African, Antarctic, Indo-Australian and South American plate.
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.
This list of Earth statistics provides all the numbers of our home planet. For example, here are size, rotation, density, temperature, orbit, age and more.
Conservative or transform plate boundaries slide across each other. They neither converge or diverge such as parts of the North American and Pacific Plate.
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.
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.
97% of scientists agree humans are causing global climate change. For example, evidence includes rising sea levels, warming oceans and shrinking ice sheets.
As temperatures surge, sea levels rise with it. This is because melting ice sheets add to total water volume. By 2100, water levels could rise 32-68 inches.
