|
Define an element
|
Chemical matter made up on one kind of atom
|
|
|
Name the three components of an atom
|
Nucleus of porotns and neutrons, surrounded by a shell orbiting electrons
|
|
|
Which two elements form the largest amount of mass in our known universe?
|
hydrogen and helium
|
|
|
The sun is composed mostly of one element. Which one?
|
hydrogen 92%
|
|
|
What process does the sun use to create about 10 elements?
|
Nuclear fusion
|
|
|
How are most of the natural elements in our universe created?
|
From previous supernovas (exploding massive stars)
|
|
|
Should we expect to find many new elements in other solar systems and galaxies?
|
No. We should expect to find the same elements, compounds and minerals everywhere in our universe
|
|
|
What are the four most abundant elements in the earth's crust?
|
Oxygen
Silicon Aluminum Iron |
|
|
How different should minerals be on other planets, when compared to those on earth?
|
The formation of space dust and molecules are the same for all galaxies: The "initial" rocks = same
|
|
|
Which "chemical compounds" make up the Earth's crust and mantle?
|
Rocks and Minerals (which are chemical compounds) make up both the earth's crust and mantle.
|
|
|
Define a mineral.
|
A natural occurring inorganic solid with specific crystal structure, a specific chemical composition and specific physical properties
|
|
|
Can man-made compunds be considered minerals? Why?
|
No. It is not a natural occuring substance
|
|
|
Is coal classified by geologists as a mineral? Why?
|
It is not because it is composed of decayed organic matter.
|
|
|
Why are oil, gas and coal deposits defined by the governments as minerals?
|
Tax purposes. Minerals are taxed at a higher rate than rocks
|
|
|
Is ice made in a refrigerator a mineral? Why?
|
Yes. A mineral must be a solid. Therefore Ice and Snow is considered a mineral and water is not.
