September 13, The origin of Earth’s water has long been a topic of considerable discussion and debate. Some scientists hold that the wet stuff is mostly primordial, dating back to the mountain-size building blocks that coalesced to form our planet about 4. But others think Earth was born very dry and that it took sustained bombardment by sopping-wet asteroids and comets long ago to dampen the planet to its present state. By the way, modern-day Earth isn’t as soggy as you may think: Though water covers 70 percent of Earth’s surface, the stuff makes up just 0. In two new modeling studies, researchers determined that tiny grains of dust swirling around the newborn sun in the region where Earth eventually formed could have held enough water to explain the amount on the planet today. You live here, so we figure you ought to be well grounded in Earth facts. But you might find these questions a little tough and tricky. That’s quickly enough that the planet-building boulders — which themselves grew from clumping dust grains — could have been wet enough as well.
How is Earth’s Age Calculated?
Roman poet Lucretius, intellectual heir to the Greek atomists, believed its formation must have been relatively recent, given that there were no records going back beyond the Trojan War. The Talmudic rabbis, Martin Luther and others used the biblical account to extrapolate back from known history and came up with rather similar estimates for when the earth came into being. Within decades observation began overtaking such thinking.
In the s Nicolas Steno formulated our modern concepts of deposition of horizontal strata. He inferred that where the layers are not horizontal, they must have been tilted since their deposition and noted that different strata contain different kinds of fossil.
Planet Earth is the birthplace of humanity, the cradle of human civilization, and the only known planet in our Solar System that is capable of sustaining life.
The Bible does not necessarily require us to think of the earth as 6, years old. It is true that the shortest period of time that can be computed from the genealogical lists in Genesis would place creation at about BC. However, biblical genealogies sometimes omit generations. The most obvious example of this is in Matthew 1. In ancient days genealogies did not simply trace the chronology of a family.
They were used to tell the story of a family. It was legitimate methodology to omit generations not pertinent to the story being told. The author of Genesis was certainly not concerned with giving us the date of creation. He did not have a scientific intent.
Planet Earth 3: BBC wants new series before David Attenborough turns 100
February 27, By dating the rocks in the ever-changing crust, as well as neighbors such as the moon and visiting meteorites, scientists have calculated that Earth is 4. How old are your rocks? Several attempts to scientifically date the planet have occurred over the past years.
Six months after splitting with wife Jenna Dewan, Channing Tatum has reportedly moved on, according to multiple outlets. Per Us Weekly, citing a source, the year-old star is dating British.
What is the age of the earth? How old is the earth? Subscribe to our Question of the Week: On some topics, the Bible is extremely clear. For example, our moral obligations toward God and the method of salvation are discussed in detail. Reading the Scriptures carefully, one finds that the more critical a topic is, the more directly the Bible addresses it. There are several ways of attempting to determine the age of the earth.
Every method relies on certain assumptions which may or may not be accurate. All fall in a spectrum between biblical literalism and scientific literalism.
Life on Earth may date back 3.95 bn years: study
Relative dating Studies of strata , the layering of rocks and earth, gave naturalists an appreciation that Earth may have been through many changes during its existence. These layers often contained fossilized remains of unknown creatures, leading some to interpret a progression of organisms from layer to layer. Lomonosov’s ideas were mostly speculative.

By Wayne Jackson Dr. Others allege that the Bible simply does not speak to this matter. Ross, see Van Bebber and Taylor The Basic Issue If it is true that the Bible is completely silent on this topic, then certainly we ought not to make an issue of it. But, is the Bible silent regarding the age of the earth and the human race?
We pose these questions for reflection:
Age Of The Earth
Charlie Ebbers Feb 17, There are may be as few as snow leopards left in the wild. They are famously illusive and difficult to film and have become increasingly threatened by climate change and human disturbance. The first episode of the six-part series premieres February Like the original, each episode of Planet Earth II gives viewers an intimate look at a specific environment—from islands to mountains to cities—all narrated by year-old David Attenborough and with music from Hans Zimmer.
Part of the reason for the ten-year gap between series:

Several Christian ministries promote the idea that the earth is less than 10, years old, which they say comes from the Bible. In reality, the Bible makes no claim as to the age of the earth, although it does establish a minimum age. This page examines some of the history of the controversy—what the Bible actually says and does not say—and the scientific evidence surrounding the age of the earth. Age of the earth according to the Bible The following is a summary of the biblical evidence presented on this website regarding the age of the earth.

History of the age of the earth As indicated earlier, the Bible does not fix the age of the earth, contrary to the claims of Answers in Genesis. Archbishop Ussher took the genealogies of Genesis, assuming they were complete, and calculated all the years to arrive at a date for the creation of the earth on Sunday, October 23, B.
There are a number of other assumptions implicit in the calculation. The first, and foremost, assumption is that the genealogies of Genesis are complete, from father to son throughout the entire course of human existence. The second assumption is that the Genesis creation “days” were exactly hours in length.

April 19, Erosion, Weathering, Relative Dating The geological definition of weathering is simply breaking something down and erosion is moving it, usually through wind or rain. Hoodoo is a geological name for a pillar of rock, usually of fantastic shape, left by erosion. Most believe that the Hoodoos were formed by wind. But according to brycecanyon. Water, ice and gravity were the three factors in the creation of these spires.
The Paunsaugunt Plateau was uplifted by the Colorado Plateau. Water flowed through the joints a type of strain in rock deformation with no movement along the fracture and over time, they cut out these deep slot canyons. Only a small amount is absorbed by the soil which is very thin so run off happens a lot. Frost wedging is another huge factor in the history of the formation of these hoodoos as well as the on-going process.
Frost wedging is a process of weathering when water infiltrates fractures in rocks and freezes, then the force of expansion is great enough to break the rock into smaller pieces. The resulting debris is washed down by the melting of snow, monsoons and gravity. If wind had been an eroder then the edges of the hoodoos would be more rounded and not 90 degree angles. There are also laws of relative dating here:
Radiometric dating finds Earth is 2. This amazing fact seemed like alchemy to many, but American chemist Bertram Borden Boltwood was intrigued. Boltwood studied this concept of “radioactive series,” and found that lead was always present in uranium and thorium ores.
Radiometric methods for dating the earth’s rocks are based upon the decay sequences of certain elements. For example, uranium (called a parent element) will, through a series of decomposition processes, ultimately produce lead (called a daughter element).

However, just as the cat readied to attack – the wily rodent sensed danger and calmly swam away, living to fight another day. The female jaguar went hungry, but a male was to have more luck – and it was not the capybara he had in his sights.
The jaguar was seen stalking his prey on the banks of a river in the Brazilian jungle before pouncing for the kill The jaguar is the most powerful of all the big cats and pictured, he bites into the back of the caiman’s skull The jaguar drags its prey from the river as the caiman desperately thrashes about in the water The jaguar, with its unmistakable spotted coat, was captured stalking along the river bank before leaping with precision and agility into a bunch of reeds.
After a brief thrashing in the water it came out with a giant reptile lodged in its mouth – another powerful predator of the jungle – a caiman. Jaguars know exactly how to hunt caiman, biting into the back of their skulls where they are at their weakest point. Jaguars know exactly where to strike when hunting caiman, biting down into the back of their head where they are at their weakest The jaguar was described as the ‘killer of killers’ on Planet Earth II and pictured, he drags away his meal Capybara – the world’s largest rodents – looked like they were going to kick off the body-count on this week’s Planet Earth II, but escaped the prowling jaguars Sophie wrote:

Dating the Earth by the Scientific Method??? For one reason, the issue is not a scientific process. We must rely on a historical record in order to find a sensible answer to how old our planet is. Most believers admit the Bible is the only accurate record of history that remotely reaches back to the beginning. It becomes an issue of “choose ye this day whom ye will serve, whether the gods” of scientific fluctuation and guesswork, or the infallible historical account of creation given in Genesis.
The creation days of Genesis 1 consisted of an “evening” and “morning,” “light” for day, and “dark” for night Gen. If taken literally, those days were the exact equivalent as our calendar days right now.
