Let me work through each question about the rock cycle step by step.
Question 1: What kind of rock forms from sediments?
- Sediments are small pieces of rock, sand, and other materials that settle in layers
- When these layers get pressed together over time, they form sedimentary rock
- Answer: b. Sedimentary Rock
Question 2: What kind of rock forms from cooling and hardening?
- When molten rock (magma or lava) cools down and hardens, it becomes igneous rock
- "Igneous" comes from the Latin word for fire
- Answer: a. Igneous Rock
Question 3: What kind of rock forms from heat and pressure?
- When existing rocks are subjected to intense heat and pressure deep underground, they change into metamorphic rock
- "Metamorphic" means "changed form"
- Answer: c. Metamorphic Rock
Question 4: Crystals and ribbonlike layers are characteristics of
- Ribbonlike layers (called foliation) occur when minerals align under pressure
- This happens during metamorphism
- Crystals can also form during this process
- Answer: c. Metamorphic Rock
Question 5: Gas bubbles and glassy surface are characteristics of
- When lava cools very quickly, gas bubbles can get trapped inside
- Rapid cooling can also create a smooth, glassy surface
- These features are found in igneous rocks like pumice and obsidian
- Answer: a. Igneous Rock
Question 6: Fossils and sand/pebbles are characteristics of
- Fossils are preserved remains of ancient plants and animals
- They're found in sedimentary rocks because these rocks form at Earth's surface where organisms live
- Sand and pebbles are sediments that cement together to form sedimentary rock
- Answer: b. Sedimentary Rock
Final Answer:
1. b. Sedimentary Rock
2. a. Igneous Rock
3. c. Metamorphic Rock
4. c. Metamorphic Rock
5. a. Igneous Rock
6. b. Sedimentary Rock
