Types Of Rocks (Sedimentary Rocks, Metamorphic Rocks And Igneous Rocks)
This quiz is about the three types of rocks ( Sedimentary Rocks, Metamorphic Rocks and Igneous Rocks).
Questions and Answers
- 1.
Metamorphic rocks are formed from
- A.
The remain of sea creatures
- B.
The cooling of lava
- C.
Great heat and pressure in the earth
- D.
The remaining of other rocks
Correct Answer
C. Great heat and pressure in the earthExplanation
Metamorphic rocks are formed from great heat and pressure in the earth. This process occurs when existing rocks are subjected to intense heat and pressure, causing their minerals and textures to change. The heat and pressure can come from deep within the earth's crust, such as during tectonic plate collisions or from the intrusion of magma. As a result of this transformation, the original rock's structure and composition are altered, leading to the formation of metamorphic rocks.Rate this question:

Two type sof metamorphic rocks are
- A.
Gneiss and Marble
- B.
Granite and Quartz
- C.
Slate Organic
- D.
Marble and Clastic
Correct Answer
A. Gneiss and MarbleExplanation
The correct answer is Gneiss and Marble. Gneiss and Marble are both types of metamorphic rocks. Gneiss is formed from the metamorphism of igneous or sedimentary rocks, while Marble is formed from the metamorphism of limestone or dolomite. Both rocks undergo significant changes in their mineral composition and texture due to heat and pressure, resulting in their distinct characteristics.Rate this question:

Which of the following is called volcanic rock
- A.
Sedimentary Rocks
- B.
Organic Rock
- C.
Marble Rock
- D.
Igneous Rock
Correct Answer
D. Igneous RockExplanation
Igneous rock is formed through the solidification of molten material, such as lava or magma, from a volcanic eruption. This process allows for the cooling and hardening of the molten material, resulting in the formation of igneous rock. Therefore, igneous rock is commonly associated with volcanic activity, making it the correct answer in this case. Sedimentary rocks are formed through the accumulation and consolidation of sediments, organic rock is formed from the remains of organic matter, and marble rock is a metamorphic rock derived from limestone.Rate this question:

__________________ rocks are igneou rocks which are formed by slowly cooling pockets of magma that are trapped beneath the earth surface.
Correct Answer
GraniteExplanation
Granite rocks are formed by the slow cooling of pockets of magma beneath the earth's surface. This process allows for the crystallization of minerals within the magma, resulting in the formation of granite. Due to its slow cooling process, granite has a coarse-grained texture and is composed mainly of quartz, feldspar, and mica minerals. It is a common type of igneous rock and is often used in construction and as a decorative stone.Rate this question:

Three types of sedimentary rocks are______________, _____________________ and ____________________
Correct Answer
Clastic, Chemical and OrganicExplanation
The correct answer is Clastic, Chemical, and Organic. Sedimentary rocks are classified based on their origin and composition. Clastic rocks are formed from the accumulation of weathered fragments of rocks, minerals, and organic materials. Chemical rocks are formed when minerals precipitate out of solution, such as through evaporation or chemical reactions. Organic rocks are formed from the accumulation of organic remains, such as plant or animal debris. These three types of sedimentary rocks represent different processes and materials involved in their formation.Rate this question:
- 6.
Sedimentary rocks are formed either in _______________ or on ____________________.
Correct Answer
Water or landExplanation
Sedimentary rocks can be formed in two different environments: water or land. When formed in water, sedimentary rocks are created through processes such as deposition, compaction, and cementation of sediments that settle at the bottom of oceans, lakes, or rivers. On the other hand, when formed on land, sedimentary rocks are typically the result of weathering and erosion of existing rocks, followed by the accumulation and lithification of the transported sediments. Therefore, sedimentary rocks can be found in both aquatic and terrestrial environments.Rate this question:

Two type of sedimentary rocks are limestones and sandstones.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Limestones and sandstones are indeed two types of sedimentary rocks. Limestone is formed from the accumulation of shells, coral, and other organic materials, while sandstone is formed from the consolidation of sand grains. Both rocks are commonly found in various geological formations and are widely used in construction and other industries. Therefore, the statement "Two types of sedimentary rocks are limestones and sandstones" is true.Rate this question:

Metamorphic rocks are used to make jewelery.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Metamorphic rocks, such as jade, marble, and quartzite, are commonly used to make jewelry. These rocks undergo intense heat and pressure over time, resulting in their unique textures and patterns, which are highly valued for their aesthetic appeal. The durability and hardness of metamorphic rocks make them suitable for crafting into various types of jewelry, including necklaces, bracelets, and earrings. Additionally, their natural beauty and rarity add to their desirability as gemstones in the jewelry industry. Therefore, the statement "Metamorphic rocks are used to make jewelry" is true.Rate this question:

When igneous rocks are cut and carved they can be used to make statues in banks and offices.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
True. When igneous rocks are cut and carved, they can indeed be used to make statues in banks and offices, among other places. Granite, for example, is a commonly used igneous rock for sculpting due to its durability and aesthetic appeal.Rate this question:

Sedimenatry rocks are also used to make steels
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Sedimentary rocks can indeed be used to make steel. Limestone, a common sedimentary rock, is a key ingredient in the production of steel. It is used as a flux in the steelmaking process to remove impurities and facilitate the removal of slag. Additionally, sedimentary iron ore deposits, such as those found in the Mesabi Range in Minnesota, are a major source of iron for steel production. Therefore, it is true that sedimentary rocks are used in the making of steel.Rate this question:
