Answer:
Rust occurs when iron or its alloys, such as steel, corrode. The surface of a piece of iron will corrode first in the presence of oxygen and water.The process of rusting is a combustion reaction, similar to fire. Left in contact with oxygen, iron will react with the oxygen to form rust.
Hope this helps!!
An idea that is supported by some evidence, but is not yet the basis for a field of study is called a working theories.
<u>Explanation:
</u>
The combined form of one’s skills, the work experiences from testing to reveal some truth about the issues or being involved one’s work in an experiment usually called as working theory.
These type of theories are more elaborate, interconnected, make some experiences with the solution to sort out the issues and seems to be useful in event monitoring. These can be supported with certain evidences but still not acting as the basement for the field study.
Only the tiny command module survives to return to Earth. The Saturn V rocket's first stage carries 203,400 gallons (770,000 liters) of kerosene fuel and 318,000 gallons (1.2 million liters) of liquid oxygen needed for combustion
The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere. Radiatively active gases in a planet's atmosphere radiate energy in all directions
Answer:
Their discoveries both had to do with the relationship of the earth to the sun and universe. That the earth wasn't the centre of the universe and that the sun didn't rotate round the earth but rather the other way.
Explanation:
Nicolaus Corpenicius (19 February 1473 - 24 May 1543) was a scientist, astronomer and renaissance era polymath, who was fascinated with stars. He was the first to formulate a model of the universe that had the sun at the centre of the universe instead of the earth. It was such a groundbreaking discovery. Corpenicus is often referred to as the father of Modern Astronomy.
Galileo Galilie (15 February 1564- 8 January 1642) was an italian physics philosopher who was famous for his discovery that the earth rotated round the sun. it was a big deal in his time, because, the prevailing thought in his day, was that the earth was the centre of the universe and the sun rotated round the verse. Though Corpenicus was the first to discover and publish it. Further discoveries and inventions by Galileo proved corpenicus as true.
