Question

the rock cycle name: using the information in the reading passage or from your own knowledge, answer the following questions 1 how is magma formed? 2 how are sediments formed? 3 how does magma become igneous rock? 4 how do sediments become sedimentary rock? 5 how can metamorphic rock become igneous rock? 6 how can sedimentary rock become metamorphic rock? 7 how can igneous rock become sedimentary rock? 8 which kind of rock do you think would take the longest to form? why? 9 which kind of rock do you think would form the fastest? why? 10 what is the difference between intrusive and extrusive igneous rock?

Explanation:

1. Magma is formed by the melting of the Earth's mantle or crust due to high - temperature and pressure changes.
2. Sediments are formed through weathering and erosion of rocks, which break them into smaller particles that are then transported and deposited.
3. Magma becomes igneous rock when it cools and solidifies either beneath the Earth's surface (intrusive) or on the surface (extrusive).
4. Sediments become sedimentary rock through compaction and cementation, where the particles are pressed together and bound by minerals.
5. Metamorphic rock can become igneous rock if it melts to form magma first, which then cools and solidifies.
6. Sedimentary rock can become metamorphic rock when it is subjected to high - pressure, high - temperature conditions, causing physical and chemical changes.
7. Igneous rock can become sedimentary rock through weathering, erosion, transportation, deposition, compaction, and cementation processes.
8. Metamorphic rock might take the longest to form as it requires specific high - pressure and high - temperature conditions over long periods deep within the Earth.
9. Extrusive igneous rock might form the fastest as magma cools quickly on the Earth's surface.
10. Intrusive igneous rock forms beneath the Earth's surface, cools slowly, and has large crystals. Extrusive igneous rock forms on the surface, cools quickly, and has small or no visible crystals.

Answer:

1. Melting of mantle or crust due to high - temperature and pressure.
2. Weathering and erosion of rocks, followed by transportation and deposition.
3. Cooling and solidification, either intrusive or extrusive.
4. Compaction and cementation of sediments.
5. Melting to form magma first, then cooling and solidifying.
6. Subjected to high - pressure and high - temperature conditions.
7. Through weathering, erosion, transportation, deposition, compaction, and cementation.
8. Metamorphic rock; requires specific high - pressure and high - temperature conditions deep in the Earth over long periods.
9. Extrusive igneous rock; magma cools quickly on the surface.
10. Intrusive: forms beneath surface, cools slowly, large crystals. Extrusive: forms on surface, cools quickly, small or no visible crystals.
