AI Thread Summary
Huge volumes of igneous rock can indeed erupt or intrude in the middle of tectonic plates, making the statement true. While most volcanic activity is associated with tectonic plate boundaries, significant formations like flood basalts can occur in the interior, as seen in locations such as Hawaii and the Siberian Traps. The discussion highlights examples like the Columbia River Basalts and Craters of the Moon, which illustrate this phenomenon. The comparison of volcanic volumes from different geological features emphasizes the scale of these formations. Overall, the question is valid, as substantial igneous rock activity can happen away from plate boundaries.

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?

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.

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.

Thread 'Confusion regarding a chemical kinetics problem'
TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
