3.
Bog means:
Correct Answer
C. Wetland
Explanation
A bog is a type of wetland characterized by its waterlogged and acidic conditions. It is typically found in areas with poor drainage, such as marshes or swamps, and is often covered in thick layers of peat moss. Bogs are known for their unique plant communities, including sphagnum moss, heather, and carnivorous plants like sundews and pitcher plants. They play an important role in water filtration and carbon storage, as well as providing habitat for various species of birds, insects, and amphibians.
4.
Conservation means:
Correct Answer
B. Preserving And Renewing
Explanation
Conservation refers to the practice of preserving and renewing natural resources, such as water, energy, and wildlife, in order to sustain their availability for future generations. It involves using resources wisely, reducing waste, and protecting the environment. This includes activities like recycling, using renewable energy sources, and implementing sustainable farming practices. By preserving and renewing resources, we can ensure their long-term availability and minimize the negative impact on the environment.
5.
Burial ground means:
Correct Answer
A. Graveyard
Explanation
A burial ground refers to a graveyard where deceased individuals are laid to rest. It is a designated area where bodies are buried, and it serves as a final resting place for the deceased. This term is commonly used to describe a place where graves are located, and it is associated with funeral rites and mourning practices. The other options listed, such as redemption center, emissions trading, and strips of grass, do not accurately define a burial ground.
6.
Trash means:
Correct Answer
C. Garbage
Explanation
Trash refers to items that are no longer wanted or needed and are typically disposed of. It can include various types of waste such as food scraps, packaging materials, and other discarded items. The term "garbage" is commonly used to describe trash, emphasizing its nature as waste that is no longer useful or valuable. Therefore, the correct answer is "garbage".
7.
Subspecies means:
Correct Answer
A. Division
Explanation
Subspecies refers to the division of a species into smaller groups or categories based on specific characteristics or traits. It involves classifying and categorizing organisms within a species into distinct groups that share common characteristics but are different from other groups within the same species. This division helps scientists and researchers in studying and understanding the diversity and variations within a species.
8.
Moisture content means:
Correct Answer
B. Amount Of Water
Explanation
Moisture content refers to the amount of water present in a substance. It is a measure of the quantity of water contained within a material, such as soil, food, or wood. Moisture content is an important parameter in various industries, including agriculture, construction, and manufacturing, as it can affect the quality, stability, and performance of products. Monitoring and controlling moisture content is crucial to ensure the desired properties and prevent issues such as mold growth, degradation, or structural damage.
9.
Tolerance means:
Correct Answer
A. Permissible Level
Explanation
Tolerance refers to the permissible level of something, indicating the maximum amount or degree that is considered acceptable or allowed. It implies a range within which something is considered to be within acceptable limits or boundaries. In this context, tolerance refers to the acceptable level or limit of something, suggesting that it is within an allowable range or amount.
10.
Global warming means:
Correct Answer
C. Increased Earth Temperature
Explanation
Global warming refers to the long-term increase in Earth's average surface temperature. It is caused by the accumulation of greenhouse gases in the atmosphere, primarily due to human activities such as burning fossil fuels and deforestation. These gases trap heat from the sun, leading to a rise in temperatures worldwide. This phenomenon has significant impacts on the planet, including melting ice caps, rising sea levels, extreme weather events, and threats to biodiversity.
11.
Compost means:
Correct Answer
D. Decomposed Organic Matter
Explanation
Compost refers to decomposed organic matter. It is the result of a natural process called composting, where organic materials such as food scraps, yard waste, and leaves break down over time into a nutrient-rich soil amendment. Composting is an environmentally friendly way to recycle organic waste and create a beneficial product that can be used to improve soil health and fertility. Therefore, the correct answer is decomposed organic matter.
12.
Woody means:
Correct Answer
A. Contains Wood
Explanation
The word "Woody" refers to something that contains wood. It is often used to describe objects or materials that are made of or have a significant amount of wood in them. For example, a woody area refers to a place with many trees or a forest. In this context, "woody" is the most appropriate definition as it directly relates to the meaning of the word.
13.
Solubility means:
Correct Answer
C. Dissolving Capacity
Explanation
Solubility refers to the ability of a substance to dissolve in a solvent. It is a measure of the substance's dissolving capacity, indicating how much of it can be dissolved in a given amount of solvent. Solubility is influenced by factors such as temperature and pressure, and it is often expressed as grams of solute per liter of solvent.
14.
Oxidation pond means:
Correct Answer
D. Sewage Lagoon
Explanation
An oxidation pond refers to a sewage lagoon. It is a treatment system used for wastewater or sewage treatment. In this system, organic matter in the sewage is decomposed by microorganisms through a natural process of oxidation. The sewage lagoon allows for the settlement of solids and the breakdown of organic materials, resulting in the purification of the wastewater before it is discharged or reused. This method is commonly used in rural areas or small communities where centralized sewage treatment plants may not be available.
15.
Coagulation means:
Correct Answer
B. Clumping Particles
Explanation
Coagulation refers to the process of clumping particles together. In environmental regulations, coagulation is used to remove pollutants from water by causing the particles to come together and form larger, easier-to-remove clumps. This helps in the removal of impurities and improves the overall quality of water. Therefore, the correct answer is "Clumping Particles".
