Radioactive or radiometric dating allows us to estimate the Earth's age by giving us the actual age of rock within a range of several million years. Radiometric dating is based on the scientific law of radioactive decay and the half-life of radioactive elements. Uranium and some other elements decay into lead over time at a specific rate. Knowing the content of these elements in the makeup of a rock allows its age to be calculated. Currently, the oldest rocks of Earth origin are estimated to be over 4 billion years old.
We use models when studying Earth to simplify complex phenomena, make predictions, and test theories. These models help us understand Earth's processes, make informed decisions about environmental issues, and explore potential future scenarios. Additionally, they allow scientists to study phenomena that might be difficult to observe directly.
By analyzing soil composition, scientists can determine the age of Earth's surface by studying the layers of sediment and rock. By dating the materials found in these layers using techniques like radiometric dating, scientists can estimate the age of the Earth and the events that have occurred over time. This information helps us understand the Earth's history and how it has evolved over billions of years.
The total length of public roads in the US is approximately 4.1 million miles. The circumference of the Earth is about 24,901 miles. Dividing the total length of US public roads by the Earth's circumference gives us approximately 164.6. Therefore, US public roads would wrap around the Earth around 165 times.
You can't it's sort of impossible unless we make a giant ship 2x bigger than earth that has a massive weight machine that can tell us the weight of the earth in a new sort of measure ment called mega grams (mg) and 1,000,000kg is 1mg (mega gram) and this might happen in the year 200000000012 so the chances of us ever measuring the earth out of 100 is 0 = 0/100 XD
The atmosphere surrounds Earth and is made up of all the air around us.
By radioactivity which causes damage to the body and can cause cancer if enough is absorbed. Nuclear power plants do not normally emit more than trivial amounts of radioactivity, but rare faults can allow more to escape into the surrounding areas.
It is true that seismic waves from earthquakes allow us to interpret the structure of Earth's interior.
becouse it happens in a patterns
There are two forces responsible for radioactivity: the Strong nuclear force and the Weak nuclear force.
Gravity can be found everywhere on Planet Earth, the force that keeps us on the ground and doesn't allow us to fly is called gravity.
nuclear plants because the fission reaction releases lots of radioactive particles causing radioactivity..
Marie Curie is famous for her discoveries in radioactivity. She was a pioneering physicist and chemist who conducted groundbreaking research on radioactivity, leading to the discovery of the elements polonium and radium. Curie was awarded two Nobel Prizes for her work, in physics and chemistry.
You can only say, 23 years later, I-131's radioactivity almost decreases to 1/8 of original radioactivity.
I think it is said that ~70% of the earth's surface is water. 75% is close enough an estimate
Eratosthenes found out that shadows were not consistent at the same time of day in different places. He reasoned that the Earth must be a sphere to allow this.
The answer will depend on the flow rate and there is no information given which would allow us to make even an approximate estimate.
Yes it is. They allow the harmful UV rays to pass through.
