Excuse me, Mrs. Angus, I don't understand this topic on ice cores!
Yeah, I don't get the part about faults in tectonic plates or igneous rocks!
We take C02 from ice cores and have found that there is a direct variation relationship between the temperature an the amount of CO2: High CO2 = Hot and Low CO2 = Cold However, there is no way to predict the future temperature based on ice cores because CO2 is constantly changing.
Alright, we will start with ice cores! They help us determine the Earth's past climate! Here is a visual representation of an ice core. You can see where there are changes. Ice cores have bubbles that contain samples of the atmosphere at that time! We use isotopes (atoms with the same number of protons and electrons) to help us determine how the temperature has changed in Greenland and Antarctica.
After school, on the way home...
Kids: We learned about ice cores, but we're still confused about igneous rocks!
Kids: NOOO! We want to learn more! Tell us about the Law of Super-whatever!
Bus Driver: Well, what I know is that igneous rocks are formed by the cooling of magma. Oh, look at that! Sorry kids! This is your stop! You can learn about the Law Of Superposition tomorrow!
Bus Driver: Alright kids, what did you learn today?
At home, Carl asks his mom about the Law of Superposition...
Igneous rocks actually form cross-cutting relations, which is when one rock cuts across another. These igneous intrusions show that igneous rocks are always younger than the rocks that they are cross-cutting.
The Law Of Superposition states that in a sequence of undisturbed sedimentary rocks, the oldest are at the bottom and the youngest at the top.
That's cool, but what do igneous rocks have to with all of this?
At the diner, Kaleb asks Larry about faults in tectonic plates.
Dip slips are when two pieces of land change their vertical position so that one is higher than the other. Strike slips are the same thing, just horizontal.
Tectonic plates? EASY! Faults are breaks in the Earths crust that are formed by stress on either side of the rock. These are usually caused by movements in tectonic plates. The main faults are dip slips and strike slips.
Back at school...
Alright kids! Let's learn about igneous rocks and faults in tectonic plates!
Kids: No need, Mrs. Angus! We understand it already! YAAAY!!!!
