Identify the true statement. a. The contacts between plates are called passive margins. b. Plates may consist of both ocean floo
r and continental crust, but never just oceanic or continental crust. c. Plates shift the continents around as they move, so Earth's surface is constantly changing. d. There are 120 major tectonic plates.
<em>A-</em> Passive margins are the contacts between plates.
<em>B-</em> I think tectonic plates can consist of oceanic and continental crust.
<em>C-</em> Plates do shift continents as they move, it is constantly changing but quite slowly and it can take a lot of years (decades, centuries and so on). It only shifts continents further/closer about 0.6 inch a year.
