b. Degradable and non-degradable
waste
Answers
Answer:
weather:-
More specifically, weather is the mix of events that happen each day in our atmosphere. Even though there’s only one atmosphere on Earth, the weather isn’t the same all around the world. Weather is different in different parts of the world and changes over minutes, hours, days, and weeks.
Most weather happens in the part of Earth’s atmosphere that is closest to the ground—called the troposphere. And, there are many different factors that can change the atmosphere in a certain area like air pressure, temperature, humidity, wind speed and direction, and lots of other things. Together, they determine what the weather is like at a given time and location.
climate:-
Whereas weather refers to short-term changes in the atmosphere, climate describes what the weather is like over a long period of time in a specific area. Different regions can have different climates. To describe the climate of a place, we might say what the temperatures are like during different seasons, how windy it usually is, or how much rain or snow typically falls.
When scientists talk about climate, they're often looking at averages of precipitation, temperature, humidity, sunshine, wind, and other measures of weather that occur over a long period in a particular place. In some instances, they might look at these averages over 30 years. And, we refer to these three-decade averages of weather observations as Climate Normals.
B)Degradable and non-degradable waste:-
Biodegradable substances are those which decompose naturally in the environment naturally and are considered beneficial for the environment. The natural agents involved in the degradation are air, water, microorganisms, sunlight, soil, etc. Non-biodegradable substances are those wastes which do not decompose naturally in the environment, causes pollution and are also harmful to the living being.
Examples of biodegradable substances are dead plants and animals, their waste, fruits, vegetables, flower, paper, etc., while non-biodegradable substances include chemicals, paints, plastic, rubber, toxic, plastic, metals, etc.
The rate of decomposition of biodegradable substances is slow, which completes within few days or months, whereas the non-biodegradable items either do not decompose and maintain their originality or their decomposition is so slow that it may take thousands of years.
Biodegradable substances after degradation can be used to produce biogas, manure, fertilizers, compost and thus they are profitable to the environment even after degradation. But in non-biodegradable substances the degradation rate is slow, and the separation and recycling are not easy, even expensive too and is not beneficial to the environment.
Explanation:
BASIS FOR COMPARISON BIODEGRADABLE SUBSTANCES NON-BIODEGRADABLE SUBSTANCES
Meaning The wastes that decompose naturally in the environment and are considered safe for the environment are called as biodegradable substances. Such wastes which do not decompose naturally in the environment causes pollution and are also harmful to the living being are called the non-biodegradable substances.
Examples Dead plants and animals, their waste, fruits, vegetables, flowers, paper, etc. Chemicals, paints, plastic, rubber, toxic, plastic, metals, etc.
The rate of decomposition Slow. Fast.
Decomposed by Bacteria, fungi, and other living organisms have the capability of decomposing the material into the soil. These substances do not degrade easily or by the action of natural agents.
Use After degradation, they can be used to produce biogas, manure, fertilisers, compost. As their degradation rate is slow and the separation and recycling are not easy and expensive too.
Biodegradable substances are not harmful to the environment. They are harmful to the environment
