Natural Resources part 26 (Ozone Layer) CBSE class 9

TL;DR

Ozone is a molecule formed by three atoms of oxygen that acts as a protective layer against harmful ultraviolet radiation from the sun.

Transcript

hello friends this video on natural resources class 26 is brought to you by example.com don't want a exam exam so now that we are talking about oxygen let's talk about another molecule which is also made up of the oxygen atom and that is ozone now what is oxygen so oxygen is this is oxygen atoms so if I write oh that actually means one oxygen atom ...

Key Insights

• 🫀 Oxygen atoms combine to form oxygen molecules, while three oxygen atoms combine to form ozone molecules.
• 💁 Ozone is formed in the atmosphere when ultraviolet rays split oxygen molecules, allowing the formation of ozone molecules.
• 😎 The ozone layer acts as a protective barrier against harmful ultraviolet radiation from the sun.
• ❓ The ozone layer absorbs ultraviolet radiation, preventing it from reaching the Earth's surface.
• ✋ Ultraviolet radiation has high energy and can cause damage to living cells and increase the risk of skin cancer.
• 💀 Ozone, although considered a deadly poison, acts as a protective shield against ultraviolet radiation.
• 😎 The ozone layer is essential for maintaining the balance of useful and harmful radiation from the sun.

Questions & Answers

Q: How is ozone formed in the atmosphere?

Ozone is formed when ultraviolet rays from the sun split oxygen molecules, resulting in the combination of one oxygen atom with an oxygen molecule, forming an ozone molecule.

Q: Why is ozone considered a deadly poison?

Although ozone is considered a deadly poison, it acts as a protective layer by absorbing ultraviolet radiation from the sun, which can cause harm to living cells and increase the risk of skin cancer.

Q: How does the ozone layer protect the Earth?

The ozone layer forms a protective shield against harmful ultraviolet radiation from the sun by absorbing and not allowing it to reach the Earth's surface.

Q: What are the harmful effects of ultraviolet radiation?

Ultraviolet radiation can cause various diseases, including damage to DNA and proteins in the body, leading to an increased risk of skin cancer.

Summary & Key Takeaways

• Oxygen atoms combine to form oxygen molecules, while three oxygen atoms combine to form ozone molecules.

• Ozone is formed at higher levels of the atmosphere when ultraviolet rays split oxygen molecules.

• The ozone layer absorbs ultraviolet radiation, protecting against its harmful effects on living cells.
