What are some animals of the equatorial region?

Many of the world's most important rainforests lie on or near the equator. Evolution occurs more quickly near the equator and equatorial regions boast some of the Earth's greatest species diversity. Rainforests are also home to may endangered animals, due mostly to habitat loss.\nThe African elephant is the world's largest land mammal and the forest subspecies of this huge mammal makes its home in equatorial forests of western and central Africa. Equally impressive is the jaguar, which makes its home in a diversity of habitats including the equatorial rainforests of South Americ..

What is the meaning of deforestation?

As of 2014, Indonesia has the highest rate of deforestation in the world, with 15 million acres of trees disappearing between 2000 and 2012. While deforestation does provide wood for making products, many scientists are against deforestation because the trees supply oxygen, absorb carbon dioxide and anchor the soil to prevent washouts and landslides. Deforestation is one of the major factors contributing to the greenhouse effect and desertification.

What are the effects of poaching?

Quite often, poaching arises in areas dominated by economic instability. Rare plants and animals, including elephants and many exotic birds, fetch high prices on illegal markets. However, removing them from their habitats causes environmental disruption, as their delicate ecosystems are thrown into imbalance. Additionally, poaching threatens other economic opportunities in local communities, such as tourism, by making areas appear unsafe.

What is 18 knots in miles per hour?

One knot is equal to a nautical mile per hour. The term "knot" comes from a historical practice of using a tool known as a "chip log" to calculate a ship's speed. Sailors threw this tool into the water behind ships as they sailed, allowing a knotted rope to unwind freely. After a set amount of time, they would rewind the tool and count the number of knots that unwound.

What are some time differences between major cities around the world?

The difference in the local time between two cities may vary depending on the time of year, because daylight saving time, known as "summer time" in many regions of the world, is not used in some places, including Adelaide, Australia. During daylight saving time, the time in Adelaide is 15.5 hours ahead of New York City but the difference during standard time is 14.5 hours. Like most of Arizona, Phoenix does not use daylight saving time, so it is two hours behind New York City during daylight saving time and three hours behind during standard time.\nOther oddities can affect time differences be..

What was the most dangerous tornado ever recorded?

The Tri-State Tornado struck the three states on March 18, 1925. Most of the deaths occurred in southern Illinois. It traveled 219 miles and at speeds of over 70 mph. Griffin, Ill. was completely destroyed by the tornado.\nThe tornado lasted over three hours. Since there was no warning system in place, most people were caught by surprise when the tornado hit.

What happens when you mix cornstarch and water?

Fluids can be divided into Newtonian and non-Newtonian based on the way they react to applied force. Newtonian fluids, such as water, experience higher deformation as more force is applied to them. Non-Newtonian fluids, such as oobleck, experience less deformation the more force is applied. It was only fairly recently, in 2012, that a team of researchers was able to formulate a sound hypothesis as to what causes oobleck to behave the way it does. Scientists suspected that the oobleck hardened because it transferred applied mechanical force to the walls of the container. The hardening is now at..

What is the diameter of the planet Mercury?

Mercury has been shrinking since it formed billions of years ago, and scientists believe the cooling of Mercury's core has caused the rocky terrain to contract over the years. Since Mercury is a fairly small planet, it is less dense than Earth, which means it has a smaller gravitational pull. Objects and people on Mercury would weigh 62 percent less than they do on Earth, and a person could jump 2.6 times higher on Mercury.

What is the typical recovery time following ulnar nerve surgery?

After simple decompression surgery, patients can use their arms for light movement and activities. Patients should avoid gripping, pulling or pushing forcefully for at least four weeks after surgery, according to Erickson Hand Surgery.\nAfter submuscular transposition surgery, the affected arm is placed in a sling, notes NYU Langone Medical Center. Patients can expect at least three months of physical therapy following this type of surgery.

How much pressure can the human body withstand?

Intense pressure situations usually have other dangers associated with them like being deep under water. Brad Matsen explains, in "Jacques Cousteau: The Sea King," that Mr. Fargues passed away because he was under pressure for too long and lost consciousness due to oxygen toxicity while underwater, causing him to drown.\nAlso, rapid changes in pressure are perhaps more dangerous then the pressure itself. According to a BBC report, four divers were killed after going to 9 atmospheres of pressure and returning to the surface. The failure of a valve's operation caused the pressure in their d..
