Based on its key characteristics, determine if each rock sample is igneous, metamorphic, or sedimentary.
For each sample, you need to give a correct reason for your classification, based on properties displayed in the rock sample.
Answer the questions that follow the rock samples.
Rock sample 1: Identify the type of rock
Rock sample 1: What evidence do you have to back up your identification? Hint: Use the ESRT or your notes.
Rock sample 2: Identify the type of rock
Rock sample 2: What evidence do you have to back up your identification? Hint: Use the ESRT or your notes.
Rock sample 3: Identify the type of rock
Rock sample 3: What evidence do you have to back up your identification? Hint: Use the ESRT or your notes.
Rock sample 4: Identify the type of rock
Rock sample 4: What evidence do you have to back up your identification? Hint: Use the ESRT or your notes.
Rock sample 5: Identify the type of rock
Rock sample 5: What evidence do you have to back up your identification? Hint: Use the ESRT or your notes.

Match each of the metamorphic rocks listed below with one possible parent rock from the following list: bitumi-
nous coal, shale, limestone, slate, granite, sandstone.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Limestone | arrow_right_alt | Anthracite Coal |
Sandstone | arrow_right_alt | Slate |
Granite | arrow_right_alt | Marble |
Shale | arrow_right_alt | Schist |
Slate | arrow_right_alt | Gneiss |
Bituminous Coal | arrow_right_alt | Quartzite |
Base your answer on the pictures of four rocks. Each circle shows a magnified view of a rock. Which rock is metamorphic and shows evidence of foliation?
How are the three rock types classified?
Base your answer(s) to the following question(s) on the rock cycle diagram below.
State the specific names of rocks A, B, and C in the diagram. Not all rock names are used. Only one rock name should be used for rocks A, B, and C.
Obsidian
Rock Salt
Shale
Metaconglomerate
Gneiss
Rhyolite
Granite
Rock A
Rock B
Rock C
