Interesting Quiz Over Rocks And Weathering
Topic 8: Rocks and Weathering Revision Tool
Questions and Answers
- 1.
How long does it take for rocks to weather?
- A.
Hours
- B.
Seconds
- C.
Months
- D.
Years
Correct Answer
D. YearsExplanation
Rocks weather over a long period of time due to various natural processes such as temperature changes, exposure to water and air, and chemical reactions. These processes gradually break down the rocks into smaller particles or dissolve them, resulting in weathering. This is a slow and continuous process that can take several years to significantly alter the composition and appearance of rocks.Rate this question:

Which rock is a sedimentary rock?
- A.
Limestone
- B.
Slate
- C.
Marble
- D.
Granite
Correct Answer
A. LimestoneExplanation
Limestone is a sedimentary rock because it is formed from the accumulation of sediment, such as shells, coral, and other organic materials, over time. Sedimentary rocks are typically formed through the processes of weathering, erosion, and deposition. Limestone specifically forms in marine environments, where the remains of marine organisms settle and compact to create the rock. This process of sedimentation is characteristic of sedimentary rocks, making limestone the correct answer.Rate this question:

Which rock is an igneous rock?
- A.
Limestone
- B.
Slate
- C.
Marble
- D.
Granite
Correct Answer
D. GraniteExplanation
Granite is an igneous rock because it is formed through the solidification of molten magma or lava. It is composed mainly of quartz, feldspar, and mica minerals. The cooling and solidification process of molten material results in the formation of interlocking crystals, giving granite its characteristic coarse-grained texture. Limestone, slate, and marble are sedimentary and metamorphic rocks, respectively, formed through different processes. Therefore, granite is the only rock among the options that is classified as igneous.Rate this question:

Which rock is a metamorphic rock?
- A.
Limestone
- B.
Slate
- C.
Marble
- D.
Granite
Correct Answer(s)
B. Slate
C. MarbleExplanation
Slate and marble are both examples of metamorphic rocks. Slate is formed from the metamorphism of shale or mudstone, while marble is formed from the metamorphism of limestone or dolomite. Granite, on the other hand, is an igneous rock, and limestone is a sedimentary rock. Therefore, the correct answer is slate and marble.Rate this question:

Which is a type of weathering?
- A.
Freeze raw
- B.
Threeze faw
- C.
Freeze Thaw
- D.
Thaw war
Correct Answer
C. Freeze ThawExplanation
Freeze Thaw is a type of weathering where water seeps into cracks in rocks or soil, freezes, and expands, causing the material to break apart. This process is common in areas with fluctuating temperatures, particularly during winter months. As water freezes, it expands by about 9%, exerting pressure on the surrounding rock or soil. When the ice thaws, the pressure is released, causing the material to crack and break apart. This repeated freezing and thawing cycle weakens the rocks or soil over time, leading to weathering and erosion.Rate this question:

Water expands when it freezes. When slow moving streams or rivers have frozen they cause GLACIERS. What is the affect of freeze-thaw in the mountains?
- A.
It makes the mountain bigger
- B.
It breaks off pieces of rock
- C.
The rocks change types
Correct Answer
B. It breaks off pieces of rockExplanation
Freeze-thaw in the mountains refers to the repeated freezing and thawing of water in the cracks and crevices of rocks. When water freezes, it expands, exerting pressure on the surrounding rock. Over time, this process weakens and fractures the rock, causing pieces to break off. This phenomenon is known as frost shattering or freeze-thaw weathering. Therefore, the correct answer is "It breaks off pieces of rock."Rate this question:

What is a glacier?
- A.
Rivers of ice
- B.
Lakes of ice
- C.
Oceans of ice
- D.
Ponds of ice
Correct Answer
A. Rivers of iceExplanation
Glaciers are large bodies of ice that form from the accumulation and compaction of snow over many years. They flow slowly under the influence of gravity, resembling rivers of ice. As they move, glaciers can carve out valleys, transport and deposit sediment, and shape the landscape. They are found in high-altitude and polar regions, where the temperatures are cold enough for snow to accumulate and not melt completely. Glaciers are important indicators of climate change, as their retreat or advance can reflect alterations in temperature and precipitation patterns.Rate this question:

What do glaciers transport?
- A.
People
- B.
Broken Rocks
- C.
Sand
- D.
Broken rocks and sand
Correct Answer
D. Broken rocks and sandExplanation
Glaciers transport broken rocks and sand. Glaciers are large masses of ice that move slowly over land, picking up and carrying debris along the way. As glaciers move, they grind against the land, breaking rocks into smaller pieces. These broken rocks, along with the sand, are then transported by the flowing ice. This process is known as glacial erosion and is responsible for shaping the landforms in glaciated regions.Rate this question:

Why do rocks in polluted cities weather quicker?

Where is sand found?
- A.
Harper Gren School
- B.
Seaside
- C.
Deserts
- D.
Beaches
Correct Answer(s)
B. Seaside
C. Deserts
D. BeachesExplanation
Sand is found in three main locations: seaside, deserts, and beaches. Seaside areas typically have sandy shores due to the erosion of rocks and minerals over time. Deserts, on the other hand, have vast stretches of sand dunes formed by wind erosion. Beaches also have sand, which is a result of the deposition of sediments brought in by rivers or ocean currents. Therefore, all three options mentioned in the answer - seaside, deserts, and beaches - are correct locations where sand can be found.Rate this question:

How is sand made?
- A.
We don't know
- B.
By people
- C.
From rocks that have weathered
- D.
From fossils
Correct Answer
C. From rocks that have weatheredExplanation
Sand is made from rocks that have weathered over time. Weathering is the process by which rocks are broken down into smaller pieces due to exposure to elements like wind, water, and temperature changes. As the rocks break down, they become smaller and eventually turn into sand particles. This process can take thousands or even millions of years, depending on the type of rock and the environmental conditions. Therefore, sand is a result of the natural weathering process that occurs in nature.Rate this question:
