At the time that active sea-floor spreading was occurring in the Aragorn Ocean
, at what rate was new sea-floor
being created? (Think
is this related to the full spreading rate or the half spreading rate)?
There are two plate boundaries on the map.
You already highlighted one of them in Part 1, A. 1.
Highlight the other boundary also.
Give one example of each of the following types of plate boundaries on Geoworld (Note:
between two plates can vary in type from place to place).
How many lithospheric plates are there in all?
