Exam 5: Igneous Environments

What texture is displayed by the igneous rock in this photograph?

The site on the accompanying figure that would most likely form a rock that has a nonwelded texture with many fine particles is:

Which of the following is NOT a factor that affects the viscosity of magma?

The site on the accompanying figure that would mostly likely form a rock that is fine grained has small crystals but is not glassy) is:

This figure shows the formation of the Sierra Nevada batholith as magma chambers within the crust. What is the cause of melting?

The igneous rocks shown in this photograph are forming:

Which of the following igneous rocks has a texture consistent with a magma that cooled and solidified slowly at first, followed by more rapid cooling?

What does this texture indicate about the formation of this rock?

For the letters on this figure, choose the likely cause of melting for site A.

Which of the following rock types requires dissolved gas in the magma?

What is typically occurring when magmatism occurs far away from plate boundaries?

Use this graph that relates temperature and pressure to answer this question. What is required if a rock in position B moves to position A on the graph?
