Chapter 3: Lithosphere – Endogenic Processes — Online MCQ Test

Q: Which layer of the Earth is considered the outermost solid shell?

Answer: C. Crust — The crust is the thin, outermost solid shell of the Earth.

Q: What is the primary source of energy for endogenic processes?

Answer: B. Earth's internal heat — Endogenic processes are driven by the heat generated from within the Earth, such as radioactive decay.

Q: Which seismic waves travel the fastest and arrive first at a seismograph station?

Answer: A. P-waves — Primary waves (P-waves) are compressional waves that move faster than all other seismic waves.

Chapter 3: Lithosphere – Endogenic Processes — Important Questions & Answers (FAQ)

Frequently asked questions from Tamil Nadu State Board CLASS 11th GEOGRAPHY — Chapter 3: Lithosphere – Endogenic Processes, with answers and explanations. These are sample questions; the exam has its own separate question set.

Which layer of the Earth is considered the outermost solid shell?

A. Core
B. Mantle
C. Crust ✓
D. Asthenosphere

Answer: C. Crust
The crust is the thin, outermost solid shell of the Earth.

What is the primary source of energy for endogenic processes?

A. Solar radiation
B. Earth's internal heat ✓
C. Tidal forces
D. Atmospheric pressure

Answer: B. Earth's internal heat
Endogenic processes are driven by the heat generated from within the Earth, such as radioactive decay.

Which seismic waves travel the fastest and arrive first at a seismograph station?

A. P-waves ✓
B. S-waves
C. Love waves
D. Rayleigh waves

Answer: A. P-waves
Primary waves (P-waves) are compressional waves that move faster than all other seismic waves.

Compare P-waves and S-waves: Why do they provide information about the Earth's internal structure?

A. Because they speed up in the mantle
B. Because their reflection and refraction patterns change based on density and state of matter ✓
C. Because they only travel in the atmosphere
D. Because they are unaffected by the Earth's layers

Answer: B. Because their reflection and refraction patterns change based on density and state of matter
Seismic waves change speed and direction (refraction/reflection) when passing through materials of different densities and states, allowing scientists to map the interior.

In the context of the Richter scale, why is a magnitude 8 earthquake considered significantly more powerful than a magnitude 6 earthquake?

A. Because the Richter scale is a linear scale
B. Because each increase of 1 magnitude represents a 10-fold increase in amplitude and 32-fold increase in energy release ✓
C. Because the focus is always shallower in 8 magnitude earthquakes
D. Because 8 magnitude events cause volcanic eruptions

Answer: B. Because each increase of 1 magnitude represents a 10-fold increase in amplitude and 32-fold increase in energy release
The Richter scale is logarithmic; each whole number step corresponds to a 10-fold increase in wave amplitude and approximately 32 times more energy.
