What rock cools to form crystals?
- A.
Sedimentary
- B.
Metamorphic
- C.
Igneous
Correct Answer
C. IgneousExplanation
Igneous rock cools to form crystals. Igneous rocks are formed from the solidification of molten material, either magma or lava. As the molten material cools and solidifies, the atoms and molecules arrange themselves into a crystalline structure, resulting in the formation of crystals within the rock.Rate this question:

What is it that cools to form igneous rocks?
- A.
Lava
- B.
Water
- C.
Water vapour
- D.
Snow
Correct Answer
A. LavaExplanation
Lava cools to form igneous rocks. Lava is molten rock that erupts from a volcano and when it comes into contact with the cooler surface of the Earth or water, it rapidly cools and solidifies, forming igneous rocks. These rocks are formed through the process of solidification of magma or lava and can have different textures and compositions depending on the cooling rate and the mineral content of the molten rock.Rate this question:

In igneous rocks, what is it the effect the size of the crystals formed?
- A.
The amounnt of lava there is to cool
- B.
The weather conditions
- C.
The time the lava takes to cool
- D.
The height it is above or below sea level
Correct Answer
C. The time the lava takes to coolExplanation
The size of the crystals formed in igneous rocks is affected by the time the lava takes to cool. When lava cools slowly, the crystals have more time to grow and therefore become larger. On the other hand, if the lava cools quickly, the crystals have less time to develop and thus remain smaller in size. Therefore, the rate of cooling directly influences the size of crystals in igneous rocks.Rate this question:

What rock is formed due to pressure and heat?
- A.
Igneous
- B.
Matamorphic
- C.
Sedimentary
Correct Answer
B. MatamorphicExplanation
Metamorphic rock is formed due to the combination of intense heat and pressure acting on existing rocks. This process causes the minerals within the rocks to recrystallize and rearrange, resulting in the formation of metamorphic rocks. These rocks often have distinct layers or bands and can exhibit changes in texture and mineral composition. Examples of metamorphic rocks include marble, slate, and gneiss.Rate this question:

Metamorphic rock is formed from
- A.
Igenous rock
- B.
Sedimentary rock
- C.
Sedimentary and igneous rock
Correct Answer
B. Sedimentary rockExplanation
Metamorphic rock is formed from sedimentary rock because metamorphism occurs when sedimentary rocks are subjected to high temperature and pressure, causing the minerals within them to recrystallize and form new rock types. This process can result in the formation of various metamorphic rocks such as marble, slate, or gneiss. Igneous rock, on the other hand, is formed from the solidification of molten material, while sedimentary and igneous rocks can undergo weathering and erosion to form sedimentary rocks, but they do not directly transform into metamorphic rock.Rate this question:

Sand, pebbles and gravel are likely to be found in
- A.
Sedimentary rocks
- B.
Igenous rocks
- C.
Metamorphic rocks
Correct Answer
A. Sedimentary rocksExplanation
Sand, pebbles, and gravel are all types of sedimentary particles that are commonly found in sedimentary rocks. Sedimentary rocks are formed from the accumulation and consolidation of sediments, which can include particles of various sizes such as sand, pebbles, and gravel. These sediments are typically deposited in layers over time and undergo compaction and cementation processes to form sedimentary rocks. Igneous rocks are formed from the solidification of molten material, while metamorphic rocks are formed from the alteration of pre-existing rocks due to high heat and pressure. Therefore, the most likely place to find sand, pebbles, and gravel is in sedimentary rocks.Rate this question:

- A.
Heating and cooling
- B.
Freezing water
- C.
Friction
- D.
Pressure
- E.
All
Correct Answer
E. AllExplanation
All of the options listed can change rocks. Heating and cooling can cause rocks to expand and contract, leading to cracks and weathering. Freezing water can also cause rocks to crack and break apart. Friction can wear down rocks over time, resulting in erosion. Pressure can cause rocks to undergo metamorphism, changing their composition and structure. Therefore, all of these factors can contribute to the alteration of rocks.Rate this question:

Metamorphic rocks are...
- A.
Very hard rocks and not easily scratched
- B.
Soft rocks and easily scratched with a knife
- C.
Very hard rocks and easily scratched with a knife
- D.
Soft rocks and not easily scratched
Correct Answer
C. Very hard rocks and easily scratched with a knifeExplanation
Metamorphic rocks are formed through the process of intense heat and pressure, which causes the minerals in the rock to recrystallize and form a new rock. This process results in rocks that are generally very hard and resistant to scratching. However, due to the transformation of minerals, some metamorphic rocks can still be easily scratched with a knife. Therefore, the correct answer is "very hard rocks and easily scratched with a knife."Rate this question:

- D.
Soft rocks and easily scratched with a knife
Correct Answer
D. Soft rocks and easily scratched with a knifeExplanation
Sedimentary rocks are formed from the accumulation and compression of sediments over time. These rocks are typically composed of loose particles such as sand, silt, and clay, which are easily compacted and cemented together. Due to their loose and porous nature, sedimentary rocks are generally soft and can be easily scratched with a knife. This is in contrast to igneous and metamorphic rocks, which are usually much harder and not easily scratched.Rate this question:

What rocks id formed in layers?
- A.
Metamorphic
- B.
Igneous
- C.
Sedimentary
Correct Answer
C. SedimentaryExplanation
Sedimentary rocks are formed in layers through the process of sedimentation. This occurs when sediments such as sand, silt, and clay are deposited and compacted over time. As more layers accumulate, the weight and pressure cause the sediments to harden and form solid rock. Examples of sedimentary rocks include limestone, sandstone, and shale.Rate this question:

What rocks are affected by erosion and deposition?
- A.
Sedimentary
- B.
Igneous
- C.
Metamorphic
Correct Answer
B. IgneousExplanation
Igneous rocks can be affected by erosion and deposition. Erosion refers to the process of wearing away or breaking down rocks through the action of water, wind, or ice. Igneous rocks, which are formed from solidified lava or magma, can be weathered and eroded over time. Additionally, the eroded particles can be transported and deposited, forming sedimentary rocks. Therefore, both erosion and deposition can affect igneous rocks.Rate this question:

The crystals on the outside of an igneous rock are
- A.
Smaller than the crystals on the inside
- B.
Bigger than the crystals on the inside
- C.
The same size as the crystals on the inside
Correct Answer
A. Smaller than the crystals on the insideExplanation
Igneous rocks are formed from the solidification of molten magma or lava. As the molten material cools and solidifies, crystals begin to form. The rate of cooling affects the size of the crystals. When the cooling process is slow, the crystals have more time to grow larger, resulting in larger crystals on the inside of the rock. On the other hand, when the cooling process is rapid, the crystals have less time to grow, resulting in smaller crystals on the outside of the rock. Therefore, the crystals on the outside of an igneous rock are smaller than the crystals on the inside.Rate this question:

Which process occurs when sand particles settle out of the water or wind and deposit sediments?
- A.
Cementation
- B.
Uplift
- C.
Transport
- D.
Deposition
Correct Answer
D. DepositionExplanation
Deposition is the process that occurs when sand particles settle out of water or wind and deposit sediments. During deposition, the sand particles, which were previously suspended in the water or carried by the wind, lose their energy and settle down. This settling process leads to the accumulation of sediments on the surface, forming layers of sand or other types of sedimentary rocks. Deposition is an important geological process that contributes to the formation of various landforms and the preservation of fossils.Rate this question:
