CBSE Class 7 Geography Civics Geography Worksheet

Question 1. Justify the point that : "Democracy is rule of the people and is the best form of government"
Answer: Democracy is considered the finest system of governance for several clear reasons:
1. Power in the hands of citizens: People elect their representatives through regular elections. The government remains accountable to the public and serves their needs.
2. Promotes equality: Under universal adult franchise, every adult citizen has one vote with equal weight. The law treats all people equally without discrimination based on caste, religion, or gender.
3. Protects fundamental rights: Citizens enjoy essential freedoms such as freedom of speech, assembly, and belief.
4. Room to correct mistakes: If an elected government makes poor choices, citizens can replace leaders peacefully in the next election.
5. Peaceful resolution of conflicts: Democracy offers open discussion and debate to solve disagreements without violence.
In simple words: Democracy lets people choose their leaders, gives equal rights to everyone, and lets citizens change the government peacefully.

Exam Tip: Highlight keywords like "accountability", "equality", "universal adult franchise", and "rule of law" when defending democracy.

Geography

Question 1. Describe the layers of the Earth and support your answer with a diagram.
Answer: The Earth consists of three main concentric layers arranged like an onion:
1. The Crust:
- It is the uppermost, thinnest layer of the Earth.
- The continental crust is about 35 km thick and consists mainly of silica and alumina, known as sial.
- The oceanic crust is about 5 km thick and mainly contains silica and magnesium, known as sima.

2. The Mantle:
- It lies directly below the crust and extends to a depth of about 2900 km.
- It is composed of hot, dense, semi-solid rocks.

3. The Core:
- It is the innermost layer with a radius of approximately 3500 km.
- It is mainly made of nickel and iron, called nife.
- It is divided into a molten liquid outer core and a solid inner core with extremely high temperatures and pressure. In simple words: The Earth has three layers: a thin outer crust, a thick rocky mantle in the middle, and a very hot metallic core at the center.

Exam Tip: Mention the mineral abbreviations "sial" (silica and alumina), "sima" (silica and magnesium), and "nife" (nickel and iron) along with their depths to secure maximum marks.
