5 Question Rock Cycle Quiz

1.

What are the 3 types of rocks involved in the rock cycle?
- A.
  
  Sandstone, shale, basalt
- B.
  
  Dactylic, iambic, spondaic
- C.
  
  Igneous, sedimentary, metamorphic
Correct Answer
C. Igneous, sedimentary, metamorphic

Explanation
The rock cycle involves the transformation of rocks from one type to another over time. Igneous rocks are formed from the cooling and solidification of molten material, sedimentary rocks are formed from the accumulation and compaction of sediments, and metamorphic rocks are formed from the transformation of existing rocks under high heat and pressure. These three types of rocks are the main players in the rock cycle, as they represent the different stages and processes involved in the continuous formation, breakdown, and reformation of rocks on Earth's surface.

How are igneous rocks formed
- A.
  
  Molten rock that has cooled
- B.
  
  Pieces of other rocks that have collected and cemented together
- C.
  
  Mountains that have weathered away
Correct Answer
A. Molten rock that has cooled

Explanation
Igneous rocks are formed from molten rock that has cooled. When magma, which is molten rock beneath the Earth's surface, cools and solidifies, it forms igneous rocks. This process can occur either underground or on the Earth's surface. As the molten rock cools, it crystallizes and hardens, resulting in the formation of igneous rocks. These rocks can have different textures and compositions depending on factors such as the rate of cooling and the mineral content of the magma.

Rocks are made up of ...
- A.
  
  Only of organic substances that contain carbon
- B.
  
  Always of quartz and silicon
- C.
  
  Of two or more minerals
Correct Answer
C. Of two or more minerals

Explanation
Rocks are not made up of only organic substances that contain carbon, as there are many rocks that do not contain carbon-based materials. Similarly, rocks are not always made up of quartz and silicon, as there are various types of rocks with different mineral compositions. The correct answer is that rocks are made up of two or more minerals, as most rocks are composed of a combination of different minerals.

How are sedimentary rocks formed?
- A.
  
  Molten rock that has cooled
- B.
  
  Formed through the deposition and solidification of sediment
- C.
  
  Petrified trees
Correct Answer
B. Formed through the deposition and solidification of sediment

Explanation
Sedimentary rocks are formed through the deposition and solidification of sediment. This process involves the accumulation of particles such as sand, mud, and organic material, which are then compacted and cemented together over time. As layers of sediment build up, the weight and pressure from above cause the lower layers to harden into rock. This process can occur in various environments such as rivers, lakes, oceans, and deserts. Petrified trees, on the other hand, refer to the fossilization process where organic material is replaced by minerals, resulting in a rock-like structure. Molten rock that has cooled refers to igneous rocks, not sedimentary rocks.

How is rock different from a mineral?
- A.
  
  One has the name rock the other one has the name mineral
- B.
  
  A rock is a solid, inorganic, naturally-formed substance without a particular atomic structure or chemical composition. A mineral is a solid inorganic substance of natural occurrence.
- C.
  
  All are the same
- D.
  
  None of the above
Correct Answer
B. A rock is a solid, inorganic, naturally-formed substance without a particular atomic structure or chemical composition. A mineral is a solid inorganic substance of natural occurrence.

Explanation
A rock and a mineral are different because a rock is a solid, inorganic, naturally-formed substance without a particular atomic structure or chemical composition, whereas a mineral is a solid inorganic substance of natural occurrence. They have different definitions and characteristics, which distinguish them from each other.
