Input-output notes

When doing these Input - Output notes i learnt about rocks and minerals. Im going to share with you a few cool things that I learnt.  First you need to know how rocks are made, rocks are made of 2 minerals, and a special cycle called the Rock Cycle. The Rock Cycle is a model that describes the formation breakdown and reformation of a rock. There are also 3 different types of rocks, such as Igneous, sedimentary and metaphoric. Igneous rocks that are made of heat or fire. Sedimentary rocks are rocks that usually are layers of sand or mud at the bottom of oceans that have turned to rock. Lastly Metaphoric rocks are rocks that originally were sedimentary or igneous. To identify a mineral you can observe the color, luster, streak, cleavage, hardness or the specific gravity. Minerals are ofter made of molten rock that cools.

Thank you for reading my post i hope you guys learned as much as i did and understood. Read my next post!!!!

Volcano reflection

Guiding question:
               Is there a pattern in the locations of earthquakes and volcanoes?
Hypothesis:  
             Yes, because earthquakes and volcanoes are both found in subduction zones.


Analysis and conclusion: 
    1. How are earthquakes distributed on the map?  Are they scattered evenly or concentrated in zones? 
Volcanoes an earthquakes are found in zones like in the Pacific Ring of Fire, which is an area where large numbers of earthquakes and Volcanic eruptions occur in the basin of the Pacific. The Ring of Fire has 452 volcanoes and is home to over 75% of the world's active and dormant volcanoes.[1]  About 90% of the world's earthquakes and 80% of the world's largest earthquakes occur along the Ring of Fire. ( wikipedia, ring of fire)
                                                  
2. From your data, what can you infer about the relationship between earthquakes and volcanoes?
        I can infer that if there is a volcano and it erupts, the eruption moves the plates which can cause a earthquake or vic-versa. 


4. Suppose you added the locations of additional earthquakes and volcanoes to your map. Would the overall pattern of earthquakes and volcanoes change? Explain in writing why you think the pattern would or would not change. No, the pattern generally would not change because earthquakes follow tectonic plates, and volcanoes are usually in the same area.

                                              Reflection

I think i did alright not great though. I had great pictures on my power point good information great words, but i didn't have all the information to understand some of the words in my project. Also i was missing a game i had a game but sadly my server was not working at the time so i pretty much didn't have one. Out of 6 i think my grade should be 4 because i didn't know 2 words on presentation and my game and my computer wasn't working as it should have so technically i wasn't prepared. But i did have good eye  contact with the class and i had a creative power point and pics.

 During volcanoes i obviously learned about volcanoes, but i also learnt how people are affected by them. Like the Evacuation and their homes what happens to the land and about the peoples animals. Many of the people lose loved ones or their crops and homes are burned to nothin'. People are almost manipulated by these landforms that are created by another disaster. Volcanic ash can break a whole forest down. Learning about volcanoes created a question and the question for me was "can the ash from the volcano create holes in the ozone layer"?  So it caused me to researched and the answer was no it does not because the patterns do not match when testing.
