An earth science student greatly annoyed a fellow student after yelling "GNEISS!!" when the classmate tripped and fell on a large boulder. The overly eager earth science student really meant to tell the classmate that the boulder they were about to trip on

1. solidified from lava at the earth's surface
2. was a high-grade, banded metamorphic rock, with a foliated texture
3. commonly contains fossils
4. would fizz with the application of hydrochloric acid (HCI)
