Who measured earth's surface acceleration?
It's a common experiment, performed in physics classes throughout the world.
What is the main goal of miller's experiment?
To prove that organic compounds could have been generated by the conditions of primeval earth
What questions do you ask when performing an experiment?
1. What is being tested? (the aim of the experiment). 2. What is being changed? (the chosen variable). 3. What is going to be kept the same? (controlled variables). 4. What is going to be measured? (the measured variable). In general, you should ask how will your experiment help the earth, mankind, or people to accomplish a task.
Amanda is doing a report for her Earth Science class about the four seasons. Which of the following would be an effective scientific model to incorporate in her project?
A study of a tropical region on earth which would demonstrate that the four seasons model is basically flawed. Many places have fewer seasons.
Why is it important for scientist to use the scientific method?
The Scientific Method is a method followed to make experiment results repeatable, as multiple people can do the same experiment and get the same answer, making the experiment reliable. It is a base for proving the results are correct. If it was not used, people would go back to less organized science, like Aristotalian science (he claimed the sun revolved around the earth, and was believed over other scientists with the correct view because he was popular, before the scientific method's creation).
The foucault pendulum provides evidence of earth?
It provides evidence of the Earth's rotation on its axis.
Miller and urey's experiments attempted to demonstrate?
The Miller-Urey experiment combined amino acids and other chemicals thought to be a part of the primordial soup. The experiment attempted to demonstrate the conditions on Earth in its early years.
What kind of rock covered the surface of the earth during the Archean age?

The Archean Eon spans the time from the formation of the Earth until years ago?
2.5 billion years ago
How does this demonstrate that earth is spherical?
WHAT demonstrates that the Earth is spherical?!
Used to demonstrate the rotation of earth?
what is used to demontrate the rotation of earth?
What age is Archean?
the eon that constitutes the earlier (or middle) part of the Precambrian, in which there was no life on earth. It precedes the Proterozoic eon. Also called azoic .
How long ago was the Archean age relative to the entire history of the earth?
look the answer up somewhere else b i t c h
What era was when life first flourished on Earth?
The Archean Eon is the period in which the first life on Earth appeared.
Precambrian Time which includes most of Earths history began with?
Earth forming from a mass of dust and gas :)
How was archean eon environment like?
The Archean Eon was a period of time where the Earth was very hot and wet. The oceans were also very warm. Thousands of volcanic eruptions ejected volcanic ash that bombarded the earth and dust into the atmosphere causing violent lightning storms and continual rain. During this timeline the Earth atmosphere was polluted with enormous amount of Carbon and Sulfur dioxide concentration. Such levels of chemical content in the atmosphere would be very dreadful to the majority of living beings in the Earth today.
What astronomical fact did Aryabhata demonstrate awareness of?
The earth is round
