An interesting article I raed.  I listed some of my favorite questions and a few answers but you will have to go to the Space for the rest. 

1. What is the hottest place on Earth?

5. Can rocks grow?

7. How far does regular dust blow in the wind?

A 1999 study showed that African dust finds its way to Florida and can help push parts of the state over the prescribed air quality limit for particulate matter set by the U.S. Environmental Protection Agency. The dust is kicked up by high winds in North Africa and carried as high as 20,000 feet (6,100 meters), where it’s caught up in the trade winds and carried across the sea. Dust from China makes its way to North America, too.

22. Good thing California isn’t sinking further, right?

32. What is the deepest canyon in the United States?

Over the eons, the Snake River dug Hell’s Canyon along the Oregon-Idaho border. It is more than 8,000 feet (2.4 kilometers) deep. In contrast, the Grand Canyon is less than 6,000 feet deep — a bit more than a mile.

40. Why is Earth mostly crater-free compared to the pockmarked Moon?

51. Does all of Earth spin at the same rate?

58. What is the fastest surface wind ever recorded?

The fastest “regular” wind that’s widely agreed upon was 231 mph (372 kph), recorded at Mount Washington, New Hampshire, on April 12, 1934. But during a May 1999 tornado in Oklahoma, researchers clocked the wind at 318 mph (513 kph). For comparison, Neptune’s winds can rage to 900 mph (1,448 kph).

60. How old is Earth?

70. Were Earth and the Moon separated at birth?

75. How much would seas rise if the Antarctic Ice Sheet melted?

86. How much gold has been discovered worldwide to date?

More than 193,000 metric tons (425 million pounds). If you stuck it all together, it would make a cube-shaped, seven-story structure that might resemble one of Donald Trump’s buildings. First you’d have to find all those rings that have gone down the drain.

96. Have there always been continents?
