22. California is sinking?

The fact is that some parts of this state are suffering. The up and down movement of some natural lakes on the ground is making California sink 11cm / year. Underground water and sewer systems can be threatened.

The Arica region in Chile has only 0.76 mm of rainfall per year. That amount takes a century to catch a cup of coffee.

26. What causes landslides?

Heavy rainfall in a short period of time can cause high-speed sludge and garbage flows. The amount of precipitation that lasts for a long time creates large landslides slowly. Every year, the United States damages $ 2 billion due to landslides. In a record storm in San Francisco in January 1982, about 18,000 waste streams formed in one night. Property damage amounted to 66 million USD and 25 deaths.

27. How much does the sludge flow?

Flows like mudfalls can move at speeds of 160 km / h.

28. Does the earth's material flow?

You guessed it right. In 1999, scientists found melting materials in the earth's core flowing in vortices that were similar in strength to hurricanes.

29. The wettest place on earth?

The wettest land on the mainland was recorded by Guinness World Records as Mawsynram in northeastern India.

Moisture spreads from the Bay of Bengal , condensing on Khasi hills looking down on Bangladesh fields from this 1,491m high plateau, making it an incredible annual rainfall of 11,871 mm. This rainfall can flood the pillow of the world's largest statue , the 30-meter-high statue of Christ the Redeemer in Brazil.

30. Does the earth turn to different periods like the moon?

From Mars, it is possible to see the earth move through different stages (just as we see Venus change). The Earth is in the orbit of Mars and when two planets travel through the sun, sunlight hits our planet in a different angle.

31. The biggest canyon Mars?

G Canyon Canyon is considered the largest canyon system in the world, 446 km long. But Valles Marineris canyon on Mars is 4,800 km long. If placed on the US map, it will last from New York to Los Angeles. Huge scar on the surface of this red planet is up to 8 km deep.

32. The deepest canyon in America?

Hells gorge along the Oregon - Idaho border deeper than 2.4 km. Meanwhile, the Grand Canyon is no more than 2 km deep.

33. Is the Earth the largest rock planet in the solar system?

Absolutely true. The diameter of the earth at the equator is 12,756 km. Venus is 12,104 km. Mars and Mercury are much smaller. Pluto is also a rock planet but too small.

34. How many volcanoes once worked on earth?

There are about 540 volcanoes on the ground that erupted. No one knows how many volcanoes below the sea have been operating so far.

35. Does the air consist mainly of oxygen?

The earth's atmosphere accounts for 80% of nitrogen. The rest is mostly oxygen , with a very small amount of other impurities.

36. Highest waterfall in America?

Yosemite Falls in California is 739 m high.

37. What percentage of the world's water is in the ocean?

About 97%. The ocean occupies two-thirds of the earth's surface, which means that if an asteroid hits the earth it will splatter.

38. Which region contains the largest amount of fresh water in the world?

Nearly 70% of the world's fresh water is in the Antarctic and Greenland ice sheets. The rest is in the atmosphere, rivers and streams, underground water and accounts for only about 1%.

39. The largest ocean on earth?

The Pacific Ocean covers an area of ​​165 million square kilometers, more than twice the Atlantic Ocean. It has an average depth of 3.9 km.

40. Why does the earth have almost no craters, while the moon has holes?

Earth works more positively in terms of geography and weather. Some few million-year-old craters have been covered by plants, transformed through earthquakes and landslides, along with wind and rain phenomena. Meanwhile the moon is quite geographically quiet and has almost no weather, so the craters on it are still pristine through billions.
