Multiple Choice

What is the primary characteristic of alkaline basalts as described in the image?

1

They are produced by large degree of melting.

2

They are the only magmas not produced by silicate source rock.

3

They form from smaller degree of partial melting.

4

They form along convergent plate boundaries.
