Felsic lavas (dacites or rhyolites) tend to be highly viscous (not very fluid) and are erupted as domes or short, stubby flows. Viscous lavas tend to form stratovolcanoes or lava domes. Lassen Peak in California is an example of a volcano formed from felsic lava and is actually a large lava dome.
Most psychology degree courses want you to have a science related A level, so anything from biology, physics, chemistry, maths or psychology. I just finished a psychology degree and I didn't do biology at A level.

A few different avenues lead to a career in psychology, including a stand-alone master's degree, a master's completion and then later a doctorate, or a program combining the two.
