Science Buddies: "Ask an Expert"

During the Deccan eruptions roughly 66.25 million years ago, basalt from the mantle was erupted onto the continental surface.

My questions:
-Is this statement true?
-What is the continental surface?
-What does this show us? (eg. is the basalt still able to be found at the continental surface and used as evidence of this event?)

Sorry for the silly questions, very new to this topic.

The "Ask the Expert" forums are for students in grades K-12 and their parents and teachers who are doing hands-on science projects. If you are a student and are planning a hands-on science project please provide more details about your project including your hypotheses and design of the experiments you are planning. The experts here will be glad to help you. Otherwise, there are other sites on the web where your post would be more appropriate.

Thank you,
