Questions and Answers
- 1.
What large ice mass moves across land causing large grooves in earths surface?
- A.
Ice berg
- B.
Polar ice cap
- C.
Glacier
Correct Answer
C. GlacierExplanation
A glacier is a large ice mass that moves across land, causing large grooves in the Earth's surface. Glaciers are formed from compacted snow that accumulates over time and undergoes a process of recrystallization. As they move, glaciers erode the land beneath them, creating distinct features such as valleys and grooves. These grooves, known as glacial striations, are evidence of the powerful force and movement of glaciers. Therefore, the correct answer is glacier.Rate this question:

What is the most effective physical weathering agent?
- A.
Rust
- B.
Water
- C.
Wind
Correct Answer
B. WaterExplanation
Water is the most effective physical weathering agent because it has the ability to freeze and expand, causing rocks to crack and break apart. Water can also seep into cracks and crevices, eroding rocks over time. Additionally, water can carry sediment and debris, which can further wear down rocks through abrasion. Overall, the constant presence and movement of water make it a powerful force in breaking down and eroding rocks, making it the most effective physical weathering agent.Rate this question:

What can carry a lot of sediment and eventually create canyons?
- A.
Fast rivers
- B.
Erosions
- C.
Wind
Correct Answer
A. Fast riversExplanation
Fast rivers can carry a lot of sediment and eventually create canyons. As the water flows swiftly, it has the power to erode the surrounding land and transport large amounts of sediment downstream. Over time, this continuous erosion deepens and widens the river channel, forming a canyon. The force of the water, combined with the sediment it carries, carves through the rock and shapes the landscape, creating the characteristic features of a canyon.Rate this question:

What shapes the earth?
- A.
Tectonic plates
- B.
Rivers and oceans
- C.
Mountains
Correct Answer
B. Rivers and oceansExplanation
Rivers and oceans shape the earth through erosion and deposition processes. Rivers carve out valleys and canyons, while oceans erode coastlines and create beaches. Both rivers and oceans transport sediment and deposit it in different areas, leading to the formation of new landforms. Additionally, rivers and oceans play a crucial role in the water cycle, redistributing water across the earth's surface and influencing weather patterns. Therefore, the constant action of rivers and oceans has a significant impact on shaping the earth's surface.Rate this question:

What is frost wedging?
- A.
When frost kills off plants
- B.
When liquid gets into cracks in rocks, freezes, then expands
- C.
When rocks fall apart
Correct Answer
B. When liquid gets into cracks in rocks, freezes, then expandsExplanation
Frost wedging refers to the process where water enters cracks in rocks, freezes, and expands. This expansion exerts pressure on the surrounding rock, causing it to crack and break apart over time. This process is commonly observed in cold climates where temperatures fluctuate above and below freezing point. The repeated freeze-thaw cycles contribute to the gradual disintegration of rocks, eventually leading to the formation of smaller fragments and debris.Rate this question:

How does chemical wethering break down rock?
- A.
By burning it
- B.
By using acids to melt it
- C.
By changing its chemical composition
Correct Answer
C. By changing its chemical compositionExplanation
Chemical weathering is the process of breaking down rock through chemical reactions. It occurs when minerals in the rock react with substances in the environment, such as water, oxygen, or acids. This reaction results in the alteration of the rock's chemical composition, leading to its breakdown. Burning rock is not a mechanism of chemical weathering, and using acids to melt it is a form of physical weathering, not chemical. Therefore, the correct answer is that chemical weathering breaks down rock by changing its chemical composition.Rate this question:

What is an example of chemical reactions?
- A.
When Calcite reacts with Carbonic acid causing Calcium Bicarbonate
- B.
When Nuclear Plants explode
- C.
When an atom is split
Correct Answer
A. When Calcite reacts with Carbonic acid causing Calcium BicarbonateExplanation
An example of a chemical reaction is when Calcite reacts with Carbonic acid causing Calcium Bicarbonate. In this reaction, Calcite, which is a mineral composed of calcium carbonate, reacts with Carbonic acid to form Calcium Bicarbonate. This reaction involves a rearrangement of atoms and the formation of new chemical bonds, resulting in the formation of a different compound.Rate this question:

What is Erosion?
- A.
When Rocks are made smaller
- B.
When Water flows through canyons
- C.
Moving or removal of material by water, wind, ect.
Correct Answer
C. Moving or removal of material by water, wind, ect.Explanation
The correct answer is "Moving or removal of material by water, wind, etc." Erosion refers to the process of wearing away or moving of materials such as soil, rocks, or sediment by natural agents like water, wind, or ice. These agents have the ability to transport and deposit the eroded materials to different locations, leading to changes in the landscape over time.Rate this question:

What is Leaching?
- A.
When bugs attack
- B.
When minerals are made into larger minerals of rock
- C.
When rocks erode
Correct Answer
B. When minerals are made into larger minerals of rockExplanation
Leaching refers to the process in which minerals are transformed into larger minerals of rock. It involves the dissolution and subsequent re-precipitation of minerals, resulting in the formation of larger mineral aggregates. This process is commonly observed in soil formation and weathering, where minerals are gradually broken down and recombined to form new rock structures. Leaching plays a crucial role in the formation of various types of rocks and contributes to the overall geological processes on Earth.Rate this question:
