What evidence suggests that a 50,000 year old comet may have impacted Earth in the past?
Well, isn't that just fascinating to think about! Scientists noticed traces of tiny diamonds and other unique elements in geological layers around the world that aren't commonly found on Earth. This discovery sparked the theory that a cosmic visitor, potentially a comet, may have collided with our planet around 50,000 years ago, leaving behind an interesting story for us to discover and learn from. Life is full of mysteries waiting to be painted on your own artistic canvas - just like this intriguing tale from long ago.

How are the moon's craters evidence that large meteoroids probably hit Earth?
Looking at the evidence of meteor strikes on the moon is obvious. It would be logical to assume that celestial bodies have struck the earth in the past even though the evidence has been covered up by erosion, plant, growth, and other environmental factors.
What came first the moon or earth?
We're not exactly sure, but it seems most likely that the moon was formed early in the Earth's history, when a large body collided with the Earth, shearing off molten debris. This molten debris formed the Moon. Most research and models show that the moon formed either at the same time or shortly after the Earth.
How can you be sure today that the Earth orbits around the sun?
Scientific observations, experiments, and calculations show that Earth orbits the sun due to the gravitational pull between the two bodies. This theory is supported by various sources of evidence, including the motion of celestial objects, the effects of gravity, and the concept of elliptical orbits.
Which best describes the leading theory about how earth moon formed?
The leading theory about the formation of Earth's Moon is the Giant Impact Hypothesis. This theory suggests that a Mars-sized body, often referred to as Theia, collided with the early Earth around 4.5 billion years ago. The debris from this massive impact eventually coalesced to form the Moon. This theory is supported by evidence from lunar rock samples and computer simulations of planetary formation.
How is this panspermia hypothesis proved?
The panspermia hypothesis suggests that life may have originated from another planet and spread to Earth through comets or meteorites. While there is evidence to support the idea that microbial life can survive in space, there is currently no direct proof of panspermia. Scientists continue to study the origins of life on Earth and explore the possibility of life existing elsewhere in the universe to further test this hypothesis.
Fossil evidence suggests that the earliest cells on Earth were?
simple prokaryotes
How old does scientific evidence suggest the Earth is?
== == The age of the Earth is roughly 4.6 billion years.
Can oil be renewed and how?
New evidence supported by geologists world wide suggests that the earth's mantle may be the source of crude oil, in an ongoing geological process inside the earth.
What is the die theory of the earth?
The die theory of the Earth is a debunked hypothesis that suggests the Earth is hollow and inhabited by a hidden civilization. This theory is not supported by scientific evidence and is considered pseudoscience. Mainstream geology and seismology provide strong evidence that the Earth is a solid, layered structure with a molten core.
What did Walter alvarez do afer he found the iridium?
After finding Iridium, now he got enough evidence for his theory. That Iridium was from the asteroid that impacted the Earth and caused dinosaurs to perish.
What evidence suggests that earth's magnetic field may swap around in the futurw?
Evidence from magnetic minerals in ancient rocks suggests that Earth's magnetic field has reversed multiple times in the past. These reversals are recorded in the geological record as "flip-flops" of the magnetic field's orientation. Additionally, studies of the Earth's magnetic field strength and its decreasing intensity over time support the idea that a reversal may occur in the future.
Evidence suggests the universe dgan about 15 billion years ago in a?
Earth was created by the Christian God, the true God, around 6,000 years ago
How have meteoroids impacted Earth?
248,432,828,947,395,321,862,570,493,795,490,534,387.
What is the evidence for the Earth's central core being solid?
One piece of evidence for the Earth's central core being solid comes from seismic waves that travel through the Earth. S-waves are unable to travel through liquid, so their absence in the Earth's core suggests it is solid. Additionally, studies of the Earth's magnetic field and how it behaves support the idea of a solid inner core.
What are the different theories about the shape of the earth?
The main theories about the shape of the Earth are the spherical Earth theory, which posits that the Earth is a sphere, and the flat Earth theory, which incorrectly suggests that the Earth is flat. The spherical Earth theory is supported by scientific evidence such as images of the Earth from space and the way ships disappear over the horizon.
Was there an earth before this one?
The scientific consensus is that the Earth has existed for approximately 4.5 billion years, and no evidence suggests that there were previous versions of Earth before our current one. The concept of previous Earths belongs more in the realm of mythology or pseudoscience.
If you were to take all the blood vessels in the human body and lay them end to end they would span 50000 miles and circle the earth how many times?
50000 is not as much as the earth. So 0
