Key Topics Covered In NCERT Solutions for Class 9 Science Chapter 14:
NCERT Solutions for Class 9 Science Chapter 14 question answer explain ambient temperature, water, and energy food. In addition, it illustrates with examples the resources available on the Earth which are the critical factors for all life forms to exist. Students will learn about the Earth’s outer crust’s land, water, and air. In addition, they will study the life of living organisms, cloud formation and various processes involved in soil formation..
Some of the key topics featured in NCERT Solutions for Class 9 Science Chapter 14 are:
1. The Breath of Life: Air
The atmosphere covers the Earth like a blanket, and we know that air is a bad conductor of heat. The atmosphere keeps the Earth’s average temperature reasonably steady during the day. The atmosphere can be heated by the radiation from the land as well as radiation from the water bodies. Upon getting heated, convection currents are set up in the air.
2. Air Pollution
Air pollution is any physical, chemical, or biological change in the air. This is caused by the contamination of air by harmful gases, dust, and smoke. . It can severely affect plants, animals, and people. The atmosphere contains a certain amount of gases. A decrease or increase in the amount of these gases can be harmful for survival. Global warming is a result of this imbalance in gaseous composition.
3. Water pollution
Water pollution is the contamination of water bodies. Water pollution occurs when industrial and agricultural effluents contaminate water bodies like rivers, lakes, and oceans. All life forms are affected by water pollution. It can affect the life forms found in water bodies in various ways. . Therefore, water contamination can have devastating effects on life in the long run..
To understand how water pollution contaminates water bodies, students can refer to our NCERT Solutions for Class 9 Science Chapter 14.
4. The Nitrogen Cycle
The nitrogen cycle is a biogeochemical reaction in which nitrogen is converted into many forms. It is continuously passed from the atmosphere to soil to organisms and back to the atmosphere. It involves many processes, including nitrogen fixation and denitrification. There are two types of nitrogen gas: organic and inorganic. The organic nitrogen found in living organisms is passed along the food chain through the consumption of other living creatures.
The atmosphere is rich in inorganic forms of nitrogen. Symbiotic bacteria can convert inert nitrogen to usable formats, such as nitrites or nitrates. To maintain balance in an ecosystem, nitrogen undergoes many types of transformation. Further, this process can be extended to other biomes, with the marine nitrogen cycle being the most complex biogeochemical cycle.
Students can refer to NCERT Solutions for Class 9 Science Chapter 14 to get detailed information on the formation of the nitrogen cycle.
5. The Water Cycle
This describes the constant movement of water above, below, and on the Earth’s surface. There are many processes involved in water movement apart from the significant steps. The water cycle involves different stages that include evaporation, sublimation, condensation, precipitation, infiltration, and runoff.
6. The Carbon Cycle
Along with the carbon and nitrogen cycles, the oxygen cycle plays a vital role in maintaining life. The oxygen cycle is one biological process that helps carry oxygen levels by moving through three major spheres on the Earth:
- Atmosphere
- Lithosphere
- Biosphere
This biogeochemical cycle explains the movement of oxygen gas in the atmosphere, ecosystem, biosphere, and Lithosphere. The oxygen cycle is interconnected to the carbon cycle. Therefore, the atmosphere and carbon cycle are correlated to each other. Consequently, it affects the global climatic conditions and may also affect the oxygen cycle.
The atmosphere is the layer that contains gases above the Earth’s surface. A biosphere is the sum of all Earth’s ecosystems. The outer solid portion present on the Earth’s crust is called the Lithosphere. It is the largest source of oxygen.
7. Ozone layer
The standard form of elemental oxygen is a diatomic molecule. In the upper atmosphere, however, a molecule contains three atoms. This would be O3, and it is known as ozone. Ozone, unlike the diatomic molecule oxygen, is poisonous. It is also not stable close to the Earth’s surface. It serves an important function where it is found. It absorbs harmful radiation from the Sun. It prevents harmful radiations from reaching Earth’s surface, where they could cause damage to many forms of life.
Further, students can refer to NCERT Solutions for Class 9 Science Chapter 14 to understand the harmful radiation in detail.
