To solve the "What Type" questions, we need to carefully analyze the descriptions provided for each type of rock (Igneous, Sedimentary, and Metamorphic) and match them with the characteristics described in the questions. Let's go through each question step by step:
---
Question 1: What type of rock might contain evidence of past life?
-
Description Analysis: The description for
Sedimentary rocks mentions that they often contain fossils of plants or animals.
-
Answer:
Sedimentary
---
Question 2: What type of rock contains large crystals?
-
Description Analysis: The description for
Igneous rocks states that magma-produced igneous rocks have large mineral crystals.
-
Answer:
Igneous
---
Question 3: What type of rock might contain holes from gases?
-
Description Analysis: The description for
Igneous rocks mentions that lava-produced igneous rocks can have gas bubbles or tiny crystals that formed outside on the Earth's surface. These gas bubbles can leave holes in the rock.
-
Answer:
Igneous
---
Question 4: What type of rock has visible flat layers?
-
Description Analysis: The description for
Sedimentary rocks explicitly mentions that they are composed of rounded grains or fragments of other rocks cemented together in layers.
-
Answer:
Sedimentary
---
Question 5: What type of rock changes by intense heat / pressure?
-
Description Analysis: The description for
Metamorphic rocks states that they are formed inside the Earth from heat and pressure, causing a change in the original rock.
-
Answer:
Metamorphic
---
Question 6: What type of rock contains rounded grains?
-
Description Analysis: The description for
Sedimentary rocks mentions that they are composed of rounded grains or fragments of other rocks cemented together.
-
Answer:
Sedimentary
---
Question 7: What type of rock comes from liquid rock material?
-
Description Analysis: The description for
Igneous rocks states that they are formed from molten rock (magma or lava), which is liquid rock material.
-
Answer:
Igneous
---
Question 8: What type of rock has wavy banding / layers?
-
Description Analysis: The description for
Metamorphic rocks mentions that visible layers may be bent or distorted due to the intense heat and pressure they undergo. This bending can result in wavy banding or layers.
-
Answer:
Metamorphic
---
