This is a very tough question. Just how many different species are there on Earth? Well, there will never be an exact answer to this question. Current estimates will help to give insight to just how many different species actually exist. It’s estimated that there are somewhere from 5 to 30 million different species on Earth. Of this estimation, about 2 million species have actually been identified and described.
The tallest mountain in the world is Mt Everest at 29,029 ft high. Mt Everest, part of the Himalaya Mountains is located between Sagarmatha Zone, Nepal, and Tibet, China. Mt Everest is the highest mountain measured by its summit above sea level.
Although, Mt Everest is not the tallest mountain if measured from top to bottom. Rather Mauna Kea is taller if you measure it from its base below sea level to its peak above sea level. Mauna Kea which is an inactive Hawaiian volcano is 33,465 ft in total height.
Here’s the highest mountains for each of the seven continents (measured in meters):
| Mountain Peak | Continent | Height |
| Mount Everest | Asia | 8,850 m |
| Aconcagua | South America | 6,959 m |
| Mount McKinley | North America | 6,194 m |
| Kilimanjaro | Africa | 5,895 m |
| Mount Elbrus | Europe | 5,642 m |
| Vinson Massif | Antarctica | 4,897 m |
| Mount Kosciuszko | Australia - Oceania | 2,228 m |
Waterspouts are simply tornadoes that exist over a body of water. They are often much weaker than land-based twisters due to atmospheric differences.
Waterspouts are able to pick up the water and swirl it in its funnel. In some occasions, waterspouts have picked up tadpoles, lizards and fish which eventually rained down from the sky once the waterspout diminished.
These forces of nature often occur in tropical regions where there are oceans and lakes but can also occur in less tropical areas such as the Great Lakes. Ships out on the open seas have reported seeing up to as many as 30 waterspouts in one day!
The answer to this question has not changed since the last Apollo mission. The last lunar landing occurred on December 11, 1972. Since then, no one else has walked on the surface of the moon.
The Apollo missions allowed 12 people to touch ground on the moon. All 12 of these people were American. No other country has landed people on the moon’s surface. The list is as follows:
Apollo 11 July 20, 1969:
1 Neil Armstrong
2 Buzz Aldrin
Apollo 12 November 19-20, 1969:
3 Pete Conrad
4 Alan Bean
Apollo 14 February 5-6, 1971:
5 Alan Shepard
6 Edgar Mitchell
Apollo 15 July 31–August 2, 1971:
7 David Scott
8 James Irwin
Apollo 16 April 21-23, 1972:
9 John W. Young
10 Charles Duke
Apollo 17 December 11-14, 1972:
11 Eugene Cernan
12 Harrison Schmitt
While all of the Apollo missions were 3-man missions, one of the crew members stayed in orbit around the moon while the other two decended towards the moon.
Even with all of the advances in technology, no one has been back since the early 1970’s.
Natural gas is composed of decayed organic material from millions of years ago. Natural gas is the byproduct from the remains of ancient plants and animals that became trapped underground. This matter combined with a lack of oxygen and increasing pressure and heat changed into coal, oil, and natural gas.
At first, natural gas was regarded as be unuseful and it was initially burned off as it was extracted from the ground. In 900 BC, China began using natural gas to evaporate salt water in order to produce salt. The Romans were also aware of natural gas as they witnessed a “burning spring” near Grenoble, France.
In 1865, the first U.S. natural gas company was developed. The first pipeline constructed from hollowed logs ran from a gas field to Rochester, New York in 1872. After the invention of the Bunsen burner in 1885, natural gas was used for lighting, cooking and heating. It wasn’t until World War II that natural gas pipelines was frequent enough to many large cities. By this time, it was starting to become an alternative to other fuels such as electricity and coal.
In 2000, there were more than 600 natural gas processing plants in the United States alone. With more than three hundred thousand miles of natural gas pipelines, roughly 70% of all homes are heated using natural gas today.
QUICK FACT: This originally oderless gas has been given an artificially distinct smell (like rotten eggs) so it can be detected in case of gas leaks.
As of February 2008, the worldwide population is believed to have reached over 6.6 billion people. At this current pace, the Earth would reach a human population of nine billion by the year 2050. The 2007 CIA World Factbook claims that the current population increases by 211,090 people per day.
From DSW-Datareport 2006 (”Deutsche Stiftung Weltbevölkerung”), here’s the list of the most populous nations:
Earth’s carrying capacity based upon economic factors, land, natural resources… ect. will eventually come under too much stress. When referring to the ever-booming population, how much is too much?

Ever wonder what the most dangerous animal in America is? Find out.
The moon is slowly creeping away from Earth. It’s a nearly insignificant displacement but it moves 3.8 cm further into space every year. This has been determined since the 1970’s using laser ranging measurements.
When the moves 14,600 miles into space, we will no longer see a total eclipse of the sun. Don’t worry about that though because it’s going to take 500 million years until that happens.
What is the most dangerous animal lurking around in America? Some would say the fierce grizzly bear or prowling mountain lions. They have been known to kill people, but the numbers are far from staggering. During the 20th century, 128 people died from bear attacks and only 14 people died from the mountain lions.
The answer to this question is deer (hence the picture). While you may think these animals are cute roaming around in the woods, they have been a serious problem around cities and residential areas. According to the U.S. Department of Transportation, it is estimated that 130 people die yearly from vehicle collisions with deers.
There are one and a half million deer/vehicle accidents per year. This results in nearly 30,000 injuries and over one billion dollars in health insurance claims. Deers also carry ticks which are transmitters of the deadly Lyme disease. Lyme disease infects around 13,000 people on yearly basis.
Based on a study from July 1, 2004 to June 30, 2005, The states with the highest number of accidents caused by deers are Pennyslvania, Michigan, Illinois, Ohio and Georgia. By being attentive on the roads, the number of deer-related accidents can be decreased. The following are a few good tips to follow to reduce your risk of becoming a deer-collision victim.
By following these simple steps, you are more likely to avoid deer-related accidents.
Deserts are defined as large areas of land that receive very little precipation which in return limits the amount of life desert’s support. Deserts, which cover a third of the land on Earth, receive an annual precipitation of less than 25 cm per year. Not all of the desert’s landscape is barren though. While much of the wildlife and plants are sparse, the plant life is very diverse. Plants are able to survive in this climate by maintaining two special features. These features include the ability to collect and store water and the ability to reduce water loss.
Most envision deserts to be fiercely hot with a relentless sun, but this is not always true. Many deserts are hot during the day and cold at night while others are constantly cold like the Gobi Desert in Asia. The following list some unique facts that you may find interesting.
