Is there life in earth?
Answ2. Yes there are life forms in earth. worms, insects and bacteria. In the Antarctic, they have even found life-forms inside what appears to be solid rock.
What is the half life of the earth's magnetic field?
The half-life of the Earth's magnetic field is estimated to be around 1,000 years. This means that the strength of the magnetic field decreases by half every 1,000 years. The field is generated by the motion of molten iron in the Earth's outer core.
Will earth be different if the earth was half its mass?
It the earth was half its mass, then it might only be able to hold half the atmosphere. In this case, it may not be able to maintain many species of life as we know it.
Assume that the age of the Earth is 4.6 billion years. How many half-lives of Rubidium-87 does the age of the Earth represent?
The half-life of Rubidium-87 is about 48.8 billion years. To determine the number of half-lives in 4.6 billion years, you divide the age of the Earth by the half-life of Rubidium-87: 4.6 billion years / 48.8 billion years ≈ 0.0943 half-lives. Thus, the age of the Earth represents approximately 0.09 half-lives of Rubidium-87.
What type of organisms dominated the earth for more than the first half of the history of life on earth?
Dinosaurs were the one who dominated the earth
Assume that the age of the Earth is 4.6 billion years How many half-lives of Potassium-40 does the age of the Earth represent?
Divide 4.6 billion by 1.31x109 which is the half life of Potassium-40 and you will have your answer.
What were the life forms in the precambrian era?
The Precambrian Era was the first emergence of complex, multicellular life forms on earth. Jellyfish and segmented worms were discovered to have lived during this time.
How is radioactivity of elements used to determine the age of the earth?
It finds the half-life of rocks.
What do super worms turn into during their life cycle?
Super worms turn into darkling beetles during their life cycle.
Do bees start out life as worms?
No
Which radioactive element has a half life of 4.5 billion years?
The radioactive element with a half-life of 4.5 billion years is Uranium-238. It is commonly used in radiometric dating to determine the age of rocks and materials on Earth due to its long half-life.
What element compromises half earths atmosphere?
Nitrogen compromises half of Earth's atmosphere, with oxygen making up most of the rest. Both nitrogen and oxygen are essential gases for supporting life on Earth.
