We had beads to show the plastic in the crust. We have rubber in the Mantle to show how it still can move. Then we had small washer in the outer core. In the inner core we had Washer to show the amount of iron in the core. We had washers in the outer and inner core to show the amount iron in the inner and outer core. And we had plastic to show the amount of plastic in the crust, and we had rubber in the Mantle to show I can still move.
They used the P waves which can go fast through solids, and slow through liquid's. Then when it goes through A solid they track it's speed to know it a solid or liquid. They use the secondary waves to check to see if there is any solids in the inner core of the Earth. They also use them to check where liquids are in the Earth. P waves are faster the S waves through solids and liquids.
The primary waves would be able to go through all the layers. But the secondary waves wouldn't be able to travel through the inner core. Mainly because it is made of Liquid and not solid.
3 Types of Boundaries are Convergent, Divergent, and Transform. Plate Tectonics is when a theory explaining the structure of the earth's crust. Sea floor spreading is when it forms new oceanic crust, and when magma rises up it creates new crust.
A) In the Pacific Ocean there are a lot of volcanoes, island arcs, and eruptions. What do you think is the main cause of these? Support your thoughts with theories and ideas you have learned in science class that are on your poster collage.
The mains cause of these volcanoes in the ocean are because of the oceanic crust spreading and is pushing up the new crust. One way Volcanoes are forming is because magma is rising pushing the old crust away and taking the big crust up. One way Island arcs are created is because magma is rising up and pushing the old crust away and pushing the new crust up. Another way eruptions happen is because magma is rising inside the volcanoes pushing up the magma causing a eruption.
Lost project
Absolute dating because it used a Exact age,it used radioactive dating and we used colors going in order on the timeline. Example red,blue,and orange. Red,blue,and orange. And on the rock wall we used colors going in order Example Orange,green,and red. Orange,green,and red. On the rock wall we used Relative dating,and it uses
1. Absolute dating uses and exact date.
2.Absolute uses the one rocks age to determine its age and get an exact age.
3.It's an exact age.
4.Radiometric dating.
5.Radioactive decay.
6.Age of fossils in years.
7.Quantitative method of dating.
8.Uses radiometric methods of dating.
1.Relative dating uses other rocks to find the date.
2.Relative dating uses other rocks ages to get a date around its actual age.
3.Determines the age of an object in relation to other objects.
4.Its an estimated age.
5.Index fossils.
6.Rock layers.
7.Qualitative method of dating.
8.Startigraphic methods of dating.
