The Oort cloud is spherical cloud of or shell comets nearly a light-year from the Sun. Comets are disturbed from this cloud by gravitational attraction and other factors and pass into the area occupied by the inner planets (Earth for example). Scientists then can observe these transient bodies to determine the composition of material in the Oort cloud.
By making mistakes.(:
Yes
There are many things that astronomy can teach us. Astronomy can teach us about the composition of the planets, the stars, and the moons.
Benjamin Banneker was an astronomer.
By studying the Hertzsprung-Russel diagram we can learn a great deal about the sizes colors and temperatures of stars
they learn to examine objects to learn about past people and culture
An archaeologist is a scientist who studies artifacts and objects to learn about human history and culture. They analyze ancient tools, structures, and other items to understand how past societies lived and interacted with their environment.
scientists can tell the stars composition and temperature from its spectrum. Hope tht helps :]
A scientist who examines bones, tools structures, and other objects to learn about past peoples and cultures.
Archaeologists specialize in studying objects like artifacts, structures, and other remains to understand past human behavior and societies.
He Was A Scientist Anyway
There is a good explanation of cloud computing at http://www.infoworld.com/d/cloud-computing/what-cloud-computing-really-means-031. I think you can learn most of what you need to know there.
The scientist learn about carbon levels that in the atomosphere about carbon dioxide.
Yes, I can.
no
in the desert
how did the scientist know about the information in above
