True/False Igneous Rock Formation Question

[RJLiberator]

Homework Statement

Huge volumes of igneous rock can be erupted and/or intrude in the middle of tectonic plates?
True or False

Homework Equations

The Attempt at a Solution

I am being thrown off by this rather simple problem.
I understand that at the border of tectonic plates, a lot is happening and I would expect there to be huge volumes of igneous rock formed through volcano activity. However, in the middle of tectonic plates?
I did a google search and found that there are some earthquakes that occur in the middle of tectonic plates, so I am leaning towards answering 'true.'

Anyone have any insight here?

Google "flood basalts," Hawaii, Siberian Traps, Deccan Traps.

Google "flood basalts," Hawaii, Siberian Traps, Deccan Traps.

Columbia River Basalts and the flows around Craters of the Moon in Idaho are a couple of examples on this (N. America) continent.

So, the answer they were looking for was: True.

I got this correct due to luck, but it seems like an odd question.

Volumes relative to...?
Etc.

Nonetheless, thank you guys for the comments.

Volumes relative to...?

Siberian traps are several million cubic kilometers over span of several million years. Compare that to the mid-ocean ridge, ~ 10 cm per year times 3 km crustal thickness times 40,000 km length is 12 cubic kilometers per year.
