The World of Plate Tectonics

1.
a) Pangaea was when the world was all one land mass.
b) Sea Floor Spreading is when the ocean floor is extending when two plates move apart
c) Plate Boundaries are found at the edge of the plates and there are three types: Convergent, Divergent, Conservitive.
d) The Ring of Fire are a group of volcanoes in the Pacific Ocean from Hawaii to Japan
e) The Mid-Ocean Ridge is an underwater mountain range, it usually has a rift running along its axis formed by plate tectonics.
f) A shifting north and south pole only happens once in a very very long time and they don't know why.

2. The volcanoes on the moon are extinst, which the crust is not moving and its vice versa for mars.

DUBO- 4.26mm/yr
HILO- 35.77mm/yr
KELY- 11.23mm/yr
HOFN- 14.87mm/yr
-It tells us they are slowly moving

4. The momentum of the water displaced by tectonic uplift had also dragged huge rocks. They each weigh a millions of tons
- the shape of ocean is where it originated and there was a sudden vertical rise in the sea bed
-energy released-the same as 26.3 megatons of tnt.

5.
1) the continents fit together like a puzzle
2) found fossils of animals that couldnot have survived unless the contenents were connected
3) found fossils of tropical plants in antarctica
