Air pollution in China is so severe that it can be seen from space.
A cubic meter of the Earth's atmosphere costs 6.9 quadrillion dollars.
The sizes of modern reptiles and amphibians are determined by the amount of oxygen in the atmosphere.
There is a 13-billionth of a gram of gold in a liter of seawater.
About 2000 new marine species are discovered each year.
Approximately 90% of all the garbage in the world's oceans is plastic.
2/3 of all marine species remain unexplored (there are about 1 million in total).
About 8-12 people die each year due to sharks.
More than 100 million sharks are killed annually for their fins.
Most volcanic activity (about 90%) occurs in the world's oceans. Between 10 and 20 volcanoes erupt somewhere on Earth every day. According to the United States Geological Survey, the largest earthquake in the world, with a magnitude of 9.5, occurred in Chile on May 22, 1960.
The Hawaiian volcano Kilauea is the most active in the world, erupting more frequently than any other.
The most powerful and destructive volcanic eruption on Earth occurred in 1815 on Indonesia's Mount Tambora. The roar and thunder of the raging element were heard nearly 2000 kilometers away, in Sumatra. The eruption claimed the lives of more than 70,000 people.
Every year scientists detect half a million earthquakes, of which one hundred thousand can be felt even without special instruments. Almost every 5 days, an earthquake occurs on Earth that can lead to varying levels of destruction. About 90% of earthquakes in the world occur along the Ring of Fire, an area in the Pacific Ocean basin.
The area of the Pacific Ocean exceeds the total area of land. The diameter of a sphere containing all the water on Earth could be 860 kilometers. If all the water in the world's oceans were evenly distributed over the surface, it would form a layer more than 2.7 kilometers thick. Seas lose more water due to evaporation than they receive from precipitation, while on land it is the opposite. Water continuously circulates on the globe, with its total amount remaining unchanged. The average depth of the oceans, which cover 70% of the planet's surface, is 4 kilometers.
The Mariana Trench is the deepest. Its depth is 10,994 m below sea level.
Thanks to the tectonic plate system, there is a constant carbon cycle, which prevents the Earth from overheating.
The largest crystals were found in a Mexican mine. Their weight was 55 tons.
The largest stalagmite in the world was discovered in Cuba in San Martin — its height is 67.2 meters.
Bacteria exist even at a depth of 2.8 kilometers.
Under the Amazon, at a depth of 4 kilometers, flows a river called "Hamza," which is about 400 kilometers wide.
The hottest point on the planet is the Libyan city of El Azizia. In 1922, a temperature record of 57.8°C was recorded here.
The coldest place on the planet is Antarctica. In winter, temperatures can drop to -73°C. The lowest temperature ever recorded on Earth was registered at the "Vostok Station" in Russia in 1983, measuring -89.2°C.
