Determine in each of the following how many solutions there.     

Compute the characteristic polynomial of the matrix (this is the polynomial you set = 0 to find the eigenvalues).

Identify if the matrix is only echelon form, reduced echelon form, or neither:

a. How does magma composition affect the nature of volcanic eruptions?b. Explain why volcanoes powered by mafic and felsic magmas are likely to erupt in different ways. c. Describe a typical eruption involving a mafic magma and contrast it with a typical eruption involving a felsic magma.

The most common kinds of clastic rocks are shale and sandstone. Explain why. Don’t just tell me that they are made of common minerals – that is circular reasoning that does not answer the question. Say more – make me know that you know the answer.
