Lead
The lead has been updated and my peer has added new content. A concise and clear introductory sentence was used to describe the article's topic and a brief description was also used to describe the article's major section. It was helpful that she described that the magma forms on the surface hence the "extruding part". She linked possible unknown terms such as "pyroclastics" which made reading easier, so you didn't have to separately look it up. The peer provided information outside the article in a well written way. She provided examples of extrusive rocks which was also very nice because some of these rocks are well known so it links common knowledge to a new topic. It was also great that she mentioned about extrusive rock forming quickly because it's on the surface and exposed to air. You can add more information to your lead section as to encompass the article’s other sections for a more overall view.
