Rock #1 is
- A.
IGNEOUS
- B.
SEDIMENTARY
- C.
METAMORPHIC
Correct Answer
A. IGNEOUSExplanation
Rock #1 is classified as IGNEOUS because igneous rocks are formed from the solidification of molten material, such as magma or lava. These rocks are typically characterized by their crystalline structure and can have a variety of textures depending on the rate of cooling. Igneous rocks can be further classified into intrusive (formed beneath the Earth's surface) or extrusive (formed on the Earth's surface) based on their formation process.Rate this question:

Rock #2 is
- A.
IGNEOUS
- B.
SEDIMENTARY
- C.
METAMORPHIC
Correct Answer
A. IGNEOUSExplanation
Igneous rocks are formed through the solidification and cooling of molten magma or lava. This process can occur either beneath the Earth's surface (intrusive igneous rocks) or on the surface (extrusive igneous rocks). Igneous rocks are characterized by their crystalline structure and can have a variety of textures, such as fine-grained or coarse-grained. Examples of igneous rocks include granite, basalt, and obsidian. Sedimentary rocks, on the other hand, are formed through the accumulation and compaction of sediments, while metamorphic rocks are formed through the alteration of pre-existing rocks due to high heat and pressure.Rate this question:

Rock #3 is
- A.
IGNEOUS
- B.
SEDIMENTARY
- C.
METAMORPHIC
Correct Answer
A. IGNEOUSExplanation
Rock #3 is IGNEOUS because igneous rocks are formed through the solidification of molten material, either magma or lava. These rocks are characterized by their crystalline structure and can be further classified into intrusive (formed underground) or extrusive (formed on the Earth's surface) based on their cooling rate. Igneous rocks often have a coarse-grained texture and can contain minerals such as quartz, feldspar, and mica.Rate this question:

Rock #4 is
- A.
IGNEOUS
- B.
SEDIMENTARY
- C.
METAMORPHIC
Correct Answer
A. IGNEOUSExplanation
Igneous rocks are formed through the solidification of molten material, either magma or lava. They are typically formed from the cooling and crystallization of molten rock, and can have a variety of textures and compositions depending on the cooling rate and mineral content. Igneous rocks are characterized by their interlocking crystals and can be further classified into intrusive (formed underground) or extrusive (formed on the Earth's surface) rocks.Rate this question:

Rock #5 is
- A.
IGNEOUS
- B.
SEDIMENTARY
- C.
METAMORPHIC
Correct Answer
C. METAMORpHICExplanation
The correct answer is METAMORPHIC because rock #5 is classified as metamorphic based on the given options. Igneous rocks are formed from the cooling and solidification of molten material, sedimentary rocks are formed from the accumulation and compaction of sediments, while metamorphic rocks are formed from the transformation of existing rocks through heat and pressure. Since there are no other options provided and the answer is given as METAMORPHIC, we can conclude that rock #5 is a metamorphic rock.Rate this question:

Rock #6 is
- A.
IGNEOUS
- B.
SEDIMENTARY
- C.
METAMORPHIC
Correct Answer
B. SEDIMENTARYExplanation
The given answer "SEDIMENTARY" is correct because sedimentary rocks are formed from the accumulation and compaction of sediments over time. These sediments can include fragments of other rocks, minerals, and organic material. Sedimentary rocks often have distinct layers or bedding, which is a characteristic feature. Examples of sedimentary rocks include limestone, sandstone, and shale.Rate this question:

Rock #7 is
- A.
IGNEOUS
- B.
SEDIMENTARY
- C.
METAMORPHIC
Correct Answer
B. SEDIMENTARYExplanation
The correct answer is "SEDIMENTARY" because sedimentary rocks are formed from the accumulation and compaction of sediments over time. These sediments can include fragments of other rocks, minerals, and organic materials. Sedimentary rocks are typically layered and can contain fossils, indicating that they were formed in environments such as rivers, lakes, or oceans.Rate this question:

Rock #8 is
- A.
IGNEOUS
- B.
SEDIMENTARY
- C.
METAMORPHIC
Correct Answer
C. METAMORpHICExplanation
Rock #8 is classified as metamorphic because it has undergone a process of transformation due to intense heat and pressure. This process causes the original rock to change its mineral composition and texture, resulting in a new type of rock. Metamorphic rocks are typically formed deep within the Earth's crust and can be identified by their distinct banding or foliation patterns. Examples of metamorphic rocks include marble, slate, and gneiss.Rate this question:

- 9.
Rock #9 is
- A.
IGNEOUS
- B.
SEDIMENTARY
- C.
METAMORPHIC
Correct Answer
C. METAMORpHICExplanation
The given question is asking about the type of rock that Rock #9 is. The correct answer is "METAMORPHIC." This means that Rock #9 has undergone a process called metamorphism, which involves the transformation of existing rock types due to high pressure, temperature, or chemical changes. Metamorphic rocks are formed from other types of rocks, such as igneous or sedimentary rocks, through this process.Rate this question:

- 10.
Rock #10 is
- A.
IGNEOUS
- B.
SEDIMENTARY
- C.
METAMORPHIC
Correct Answer
C. METAMORpHICExplanation
The given answer, METAMORPHIC, suggests that Rock #10 has undergone a transformation due to heat and pressure. Metamorphic rocks are formed from pre-existing rocks that have been subjected to high temperatures and intense pressure, causing the minerals and textures to change. This process usually occurs deep within the Earth's crust. Therefore, based on this information, it can be inferred that Rock #10 has undergone a metamorphic process.Rate this question:
