Question

Accepted Answer

### Question 7 (Which sequence shows how igneous rock can become sedimentary)
# Brief Explanations:
To determine how igneous rock becomes sedimentary, recall the rock cycle. Igneous rock (formed from cooling magma/lava) undergoes weathering (breaking into smaller pieces), erosion (transport of these pieces), deposition (accumulation in a new location), and compaction (pressing of sediments to form rock). Option A is for igneous rock formation. Option C is for metamorphic rock formation. Option D is not a path to sedimentary. Option B (Weathering → erosion → deposition → compaction) matches the process.
# Answer:
B. Weathering → erosion → deposition → compaction

### Question 8 (Which condition forms metamorphic rock)
# Brief Explanations:
Metamorphic rocks form from existing rocks (igneous, sedimentary, or other metamorphic) under heat and pressure without melting (if it melts, it becomes igneous). Option A forms igneous rock. Option B forms sedimentary rock. Option D is weathering (part of sedimentary rock formation or breakdown). Option C (Heat and pressure without melting) is correct.
# Answer:
C. Heat and pressure without melting

### Question 9 (Lava that cools quickly at Earth’s surface forms)
# Brief Explanations:
Lava cooling quickly at the surface forms extrusive igneous rock (fine - grained). Intrusive igneous rock forms from magma cooling slowly underground. Sedimentary rock forms from sediment compaction/cementation. Metamorphic rock forms from heat and pressure. So the correct option is B.
# Answer:
B. Extrusive igneous rock

### Question 10 (A rock contains visible layers and fossil fragments. What is the best explanation)
# Brief Explanations:
Sedimentary rocks often have layers (bedding) and can contain fossils (since they form from sediment accumulation, where organisms can be buried). Igneous rocks (formed from lava/magma) don't have fossils or layers from sediment. Metamorphic rocks (formed from heat/pressure) usually have foliation or recrystallization, not fossil - rich layers. Option B (It formed from compacted sediment) is correct as sedimentary rocks form this way.
# Answer:
B. It formed from compacted sediment

### Question 11 (What will most likely happen to sedimentary rock buried deep underground over time)
# Brief Explanations:
When sedimentary rock is buried deep, it is exposed to heat and pressure, which causes metamorphism (formation of metamorphic rock). It doesn't evaporate (rock is solid, evaporation is for liquids). It doesn't melt immediately (melting requires higher temperatures, and metamorphism happens before melting in most cases). It doesn't break into sediment (that's weathering/erosion, more common at the surface). So option C is correct.
# Answer:
C. It becomes metamorphic
