This is the simplest form of matter which cannot be broken down; contains only one kind of atom
What is an element?
100
This large celestial body is made of gas; produces heat and light through fusion
What is a star? (also accept "Sun")
100
This is the density of a mineral that has a mass of 250 g and a volume of 125 cm3
What is a density of 2 g/cm3?
100
This form of renewable energy comes from moving water (water falling over a dam)
What is hydroelectric?
100
This is the ERA in which dinosaurs lived
What is the Mesozoic? (also called "Age of Reptiles) The prefix "Meso" means "middle"
200
When reading the periodic chart, the smaller of the two numbers listed with an element's symbol is called this
What is the atomic number? (also called the number of protons, or posiitve charges in the nucleus of that element)
200
These "scars" on a moon or planets' surface are caused by collisions with objects in space
What are impact craters?
200
this instrument is used to find the mass of an object; this is used to find the length of an object.
What are a balance and a meter stick (or metric ruler)
200
This is the main fuel source (electricity) for Kansas City
What is coal? (other sources don't always work. Solar = not always sunny; wind = not always windy; hydroelectric = can't dam up the Missouri River here - too flat)
200
The Sun (and most stars) are part of this group/ class of stars
What is Main sequence stars?
300
When the atomic number is subtracted from the atomic mass, it will tell you this
What is the number of neutrons in one atom of that element?
300
This celestial body is very average; average brightness and temperature; average age; and is the center of our solar system.
What is the Sun?
300
This is how many atoms are in one molecule of this substance (orthoclase feldspar): KAlSi3O8 (NOTE) the numbers above are subscripts)
What is 13 atoms?
300
A small portion of this fuel produces an enormous amount of heat and energy; more than all other types of fuel.
What is nuclear? (uranium)
300
This former "planet" has been reclassified as a minor planet because of its very small size, doesn't "fit in" with the Gas Giants; and has an odd-shaped orbit around the Sun
What is Pluto
400
These are the symbols for each element Nickel Nitrogen lead iron
What is Ni N Pb Fe
400
Galileo thought these Moon features were oceans, which is how they got their name. We know today that they are actually ancient lava flows
What are mare?
400
these two elements MUST be present ina mineral for it to be classified as a silicate
What silicon and oxygen? (remember, silicates are the most common class of minerals on Earth)
400
This is the LEAST helpful property / characteristic in identifying an unknown mineral?
What is color?
400
This object is involved in almost every type of energy production. It produces electricity by the actions of moving water, moving steam, moving wind and produces electricty
What is a turbine?
500
This is the formula for combustion of methane (natural gas) (NOTE: the numbers listed below are subscripts) CH4 + O2 = CO2 + H2O The equation needs these coefficients to be balanced
What is 1CH4 + 2 O2 = 1 CO2 + 2 H2O
500
This diagram compares different types of stars; Red giants, white dwarfs and main squence stars. The name of this diagram is-?- and it compares two star features ? and ? (Need three answers)
What is the H-R Diagram? It compares star brightness (luminosity) and temperature
500
When looking at a ternary diagram, this is where we would find the "A" axis, the "B" axis and the "C" axis
What is "A" is horizontal line and found on the right side The "B" is at the bottom and points diagonally to the right. The "C" axis is found on the left side; points diagonally downward to the right.
500
Minerals are classified/ grouped according to their chemical formula. The largest group of minerals belong to this group
What silicates? (contain silicon and oxygen atoms in their formulas)
500
The Earth has experienced many changes during it's history. Each chunk of time had a name, certain characteristics and then ended. This certain event caused the end of the Permian Period and the Mesozoic Era.
