This is called Obsidian. It is formed from molten lava that cools so quickly that it forms a natural glass instead of crystals. What kind of rock is it?.
-
Igneous
Yes! Igneous rocks formed from magma or lava. This is an igneous rock. -
Sedimentary
No. Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. This is not a sedimentary rock. -
Metamorphic
No. Metamorphic rocks have been changed by heat and pressure from a different kind of rock. Instead of being changed, this got hot enough to completely melt, so it is not metamorphic. -
Obsidian is not a rock.
No. Obsidian is a naturally occurring solid that forms large layers in the Earth. Obsidian is a rock.

What do you have to do to replicate an experiment?
-
You do the same experiment several times.
No. Doing the same experiment several times is repetition, not replication. -
You do the same experiment that someone else did.
Yes. By replicating an experiment exactly, you should get the same results as the original experiment. -
You do an improved version of someone's experiment.
For replication, you do the experiment exactly as the original scientist did, without making any changes. -
You look for errors in someone's experiment.
The purpose of replication is to verify, not to look for errors.

Which of the following is likely a sign that it will rain soon?
-
Rising temperature
No. A warm air mass moving into your area might bring rain, but it also might bring sunny weather. Rising temperature by itself is not a good indicator of rain. -
Decreasing humidity
No. The humidity at ground level does not play much of a role in the formation of rain in the clouds. Just before it rains, the precipitation could cause the humidity to increase, but it would not cause it to decrease. -
Wind out of the west
No. Any weather front moving in from the west could cause winds, even if it was bringing clear, sunny weather. -
Falling barometric pressure
Yes! Low pressure fronts are commonly associated with rain and storms, so falling barometric pressure is a good indicator that rain may be on the way.
