1. Explain what happens to the age of oceanic crust as distance increases from a ridge? Be sure to include the vocabulary words: plate tectonic, plate spreading, continental crust, oceanic crust

Answer 1

Anybody?!

Answer 2

The age of the oceanic crust gets older as the distance increases from the ridge.

Answer 3

Cool that helps a bit :) Can I get some hints on how to form an answer with the words I listed?

Answer 4

Also if ANYBODY could check my answers for these 2 questions that would rock. Im pretty sure I got them right ^^

Analyze the above graph. Explain what the relationship is between depth of the ocean floor and the age of oceanic crust.
a. As you go deeper into the ocean floor, the younger the oceanic crust
b. As you go deeper into the ocean floor, the older the oceanic crust
c. Most of the oceanic crust is around 60 Ma
d. Pacific, Indian and Atlantic Oceans are all older than 100 Ma


Which statement is true about oceanic and continental crust compare in regards to thickness and density?
A. Continental Crust is low density and thick whereas Oceanic crust is high density and thin
B. Continental Crust is high density and thick whereas Oceanic crust is low density and thin
C. Continental crust and Oceanic crust are of the same density and thickness
D. Continental crust and Oceanic crust are both high density and Continental crust is thick whereas Oceanic

for the first one I picked B. and the second I picked A. :)

Answer 5

1. Im not sure
2. Continental Crust is low density and thick whereas Oceanic crust is high density and thin

Answer 6

Eh sorta Embarrassed about this but whatever T_T
My answer to the first question: The oceanic crust gets older as distance from the ridge increases. Plate tectonics form a valley/rift on the spine or middle of the ridge. Plate spreading in the seafloor cause magma to burst at a oceanic crust weak point, when it cools, new crust is formed away from the ridge.

How would I put in Continental Crust? I looked at the 2 Wikipedia pages but I don't really understand how to implement the Continental Crust information into my response.
