Explanation:

• Question 6: Sedimentary rocks are formed by the compaction and cementation of sediments (which can be broken rock pieces, minerals, etc.). Option A is incorrect as sedimentary rocks can form from various sources not just metamorphic rocks. Option C (heat and pressure) is for metamorphic rocks. Option D (meteorites) is not relevant to sedimentary rock formation.
• Question 7: Metamorphic rocks are formed due to heat and pressure acting on pre - existing rocks. Option A (dead organic material) is more related to some sedimentary rocks (like coal). Option C (broken sediment pieces) is for sedimentary rocks. Option D (magma) is for igneous rocks.
• Question 8: Extrusive rocks form on the Earth's surface from lava. Intrusive rocks form below the surface. So the statement "An extrusive rock forms below the surface of the Earth" is false.
• Question 9: Metamorphic rocks can undergo processes (like melting and then cooling for igneous, or weathering, erosion, compaction for sedimentary) to become other rock types over time. So the statement that it can never become another rock is wrong.
• Question 10: The word "igneous" comes from the Latin word "ignis" meaning fire. Igneous rocks are formed from the cooling and solidification of magma or lava (which is like 'fire' in the Earth's context).

Answer:

• Question 6: B. sediment or many broken rock pieces that are compacted together.
• Question 7: B. Heat and pressure
• Question 8: B. False
• Question 9: A. Become another rock
• Question 10: B. Made from fire
