DYK that the smell after rain has a name?

That earthy smell you notice after the first rain following a dry period is called petrichor.

Part of the smell comes from oils released by plants into the soil, while another important compound, geosmin, is produced by soil microorganisms. Raindrops help release these compounds into the air, making the smell much more noticeable.

It's basically a smell created by the interaction between rain, soil, plants, and microorganisms

DYK there's enough gold dissolved in Earth's oceans to make every person on the planet a millionaire... if we could extract it?

Scientists estimate that Earth's oceans contain around 20 million tons of dissolved gold.

The problem is concentration.

There are only about 13 billionths of a gram of gold per liter of seawater, making extraction far more expensive than the gold itself.

So while the oceans technically hold enormous wealth, it remains economically impossible to recover.

DYK Antarctica is considered the world's largest desert?

When most people think of deserts, they imagine endless sand dunes. However, a desert is defined by how little precipitation it receives—not by temperature.

Antarctica receives so little snowfall each year that most of the continent qualifies as a polar desert, making it the largest desert on Earth by area.

DYK the world's largest seed bank stores over 1.3 million crop varieties inside a mountain near the North Pole?

he Svalbard Global Seed Vault, located on a remote Arctic island between mainland Norway and the North Pole, was built to protect the world's food supply in case of disasters.

The vault preserves backup copies of seeds from nearly every country, allowing lost crops to be restored after wars, natural disasters, or climate-related events. The facility is dug deep into a mountain, where the naturally cold environment helps preserve seeds even if the power fails.

As of today, the vault contains more than 1.3 million seed samples, representing thousands of crop species from around the world. It has already been used in real life—seed samples were withdrawn after collections in Syria were damaged during the civil war.

The vault continues to receive new deposits and serves as one of humanity's largest safeguards against the permanent loss of agricultural biodiversity.
