Density

100
These are the two types of igneous rocks.
What are intrusive and extrusive (igneous) rock?
100
This is what lava is called when it is still inside the volcano.
What is magma?
100
This is "a small piece of solid matter" that has entered the earth's atmosphere, from somewhere in space, and fallen to earth. http://www.astrodigital.org/astronomy/met.html
What is a meteorite?
100
This quantity is measured in GRAMS and is needed to find density.
What is mass?
100
This is what magma is called after it comes OUT of the volcano.
What is lava.
200
This type of igneous rock takes longer to cool and forms larger crystals.
What is intrusive igneous rock?
200
This is the event by which magma and igneous rock become exposed to the earth's surface.
What is a volcanic eruption? (Although intrusive rocks are FORMED underground, they can be shot out of a volcano during an eruption, just like liquid lava can :-)
200
The place in space that a martian meteorite must have come from before hitting and landing on the earth.
What is Mars?
200
This quantity is measured in mL (that means milliliters), and is needed to find density.
What is volume?
200
This one is a normal question, no need to answer with "What is..." Lava made out of different kinds of liquid rock with different kinds of minerals in it will travel at different _______.
1. speeds (Lava made out of different minerals will travel at different speeds)
300
This type of igneous rock cools above ground.
What is extrusive igneous rock.
300
Magma cools in this location.
What is underground (inside the volcano).
300
This one is just a yes or no question. So answer with either "yes" or "no". Can meteorites from Mars contain trapped gases from mars as well as minerals from Mars?
Yes, (they can).
300
__________ are the units for density.
What are g/mL? (The units always look like a fraction, even though the number for density will not be a fraction. If this is confusing to you, ask Mr. Jeske or Mrs. Robinette :-)
300
This one is a normal question, no need answer with "What is..." Which one of the following two choices is an example of a UNIT OF SPEED that lava could travel. 1. grams per liter 2. feet per second
2. feet per second
400
(This one is just a regular question, no need to answer with "What is...") Can extrusive and intrusive rocks be made of the same minerals but look different?
YES...they can contain the same minerals, but look different :)
400
Pumice is an extrusive rock and Gabbro is an intrusive rock. Pumice would be associated with _________ which comes out during VOLCANIC ERUPTIONS. (Double points if you can explain why this is so).
What is lava? Double points: Pumice is associated with VOLCANIC ERUPTIONS because it is an extrusive rock. Extrusive igneous rocks are formed by lava erupting from a volcano and then cooling very quickly.
400
This one is a normal question, no need to start your answer with "What if..." What evidence is there that Mars may have had water on it at some point?
There are channels or grooves on the surface of Mars that look like they may have been carved out with water. (There is little or no evidence that water exists on the surface of Mars in our modern day).
400
Name at least two tools you would use to find the density of an object. (This question is worth double points if you can get it without a hint. It's worth regular points if you need a hint).
What is a scale (to measure mass in grams)? What is a graduated cylinder (to measure volume in mL)? What is a calculator (to divide mass by volume)?
400
This one is a true or false question, so answer either true or false. (For double points, explain why it is either true or false). Lava made from denser minerals will be thicker than a lava made from less dense minerals.
True. Double points: It is true because denser minerals are heavier and thicker. The less dense minerals will be lighter and thinner (because they have FEWER molecules packed into the same amount of space).
500
(This one is also a regular question...no need to answer it with "What is...") If an extrusive and intrusive rock contain the same minerals, why would they look different. And how would they look different?
1. they would look different because the EXTRUSIVE rock cooled much FASTER when it was made. The INTRUSIVE rock (and the minerals inside), cooled SLOWER. 2. they would look different because the intrusive rock would have time to form large crystals. The extrusive one would probably not have crystals (since it cooled so quickly).
500
(This one is a normal question, no need to answer with "What is...") _____________ is one way that magma can affect the earth's surface.
(more than one answer for this one) 1. It can erupt out of volcanoes and become lava, which cools and forms new rocks and land. 2. It can push through the land forming things like mountains.
500
One thing we can learn from a meteor made of rock from Mars. (Remember rocks are made of minerals.)
What kinds of minerals there are on Mars now, or were there a long time ago.
500
Dividing ________ by volume is how you calculate density. For double points find the density of a 5 mL ball of clay whose mass is 10 g.
What is mass? Double points: 2 g/mL
500
This one is a normal question, no need to start your answer with "What is..." If lava A travels slower than lava B. Lava A must be made up of minerals that are more ________ than lava B.
1. dense
