Let's go through each of the "What Type" questions based on the information provided in the image. We'll use the descriptions of
igneous,
sedimentary, and
metamorphic rocks to answer each question.
---
1. What type of rock might contain evidence of past life?
Answer: Sedimentary
Explanation: The description says, *"Many sedimentary rocks contain fossils of plants or animals."* Fossils are evidence of past life, so sedimentary rocks are the correct answer.
---
2. What type of rock contains large crystals?
Answer: Igneous
Explanation: The text states, *"Magma produced igneous rocks have large mineral crystals that formed inside the Earth."* Slow cooling of magma allows large crystals to form.
---
3. What type of rock might contain holes from gases?
Answer: Igneous
Explanation: The description says, *"Lava produced igneous rocks can have gas bubbles or tiny crystals that formed outside on the Earth’s surface."* Gas bubbles trapped in lava create holes (like vesicles), so igneous rocks fit this.
---
4. What type of rock has visible flat layers?
Answer: Sedimentary
Explanation: Sedimentary rocks are described as being *"composed of rounded grains or fragments... cemented together in layers."* These layers are often visible and flat, especially in rocks like shale or sandstone.
---
5. What type of rock changes by intense heat / pressure?
Answer: Metamorphic
Explanation: The definition says, *"Metamorphic rocks are formed inside the Earth from heat and pressure."* This process transforms existing rocks into metamorphic ones.
---
6. What type of rock contains rounded grains?
Answer: Sedimentary
Explanation: The description says, *"Sedimentary rocks are composed of rounded grains or fragments of other rocks..."* These grains are typically worn down by water or wind before being deposited.
---
7. What type of rock comes from liquid rock material?
Answer: Igneous
Explanation: Igneous rocks form from molten rock (magma or lava). The text says, *"Igneous rocks are formed from molten rock."* So, they originate from liquid rock material.
---
8. What type of rock has wavy banding / layers?
Answer: Metamorphic
Explanation: The description notes, *"Visible layers may be bent or distorted."* This refers to foliation or wavy banding seen in metamorphic rocks like schist or gneiss, caused by pressure and heat.
