Q1. What is the name of the weak zone of the earth's crust? Q1. What is the name of the weak zone of the earth's crust?
(A) Seismic (A) Seismic
(B) Cosmic (B) Cosmic
(C) Formic (C) Formic
(D) Anaemic (D) Anaemic
Answer: (A) Seismic Answer: (A) Seismic
The Earth's crust is not a single, unbroken shell; it's divided into large pieces called tectonic plates. The boundaries where these plates meet are subject to immense stress due to their constant movement. These areas, characterized by frequent movement and deformation, are known as seismic zones or fault zones. The accumulated stress in these weak zones is eventually released in the form of earthquakes. While the asthenosphere is a weak, semi-fluid layer beneath the lithosphere (which includes the crust), the term "seismic zone" specifically refers to the regions within the crust that are prone to seismic activity.The Earth's crust is not a single, unbroken shell; it's divided into large pieces called tectonic plates.

Q2. The Chandubi lake was formed in which year due to an earthquake Q2. The Chandubi lake was formed in which year due to an earthquake
(A) 1997 (A) 1997
(B) 1923 (B) 1923
(C) 1897 (C) 1897
(D) 1830 (D) 1830
Answer: (C) 1897 Answer: (C) 1897
Chandubi Lake is a natural lake located in Rabha Hasong Autonomous Council, Kamrup District, Assam. The lake is located at the foot of Garo Hills surrounded by Assam and Meghalaya. This lake was formed on 12 June 1897 in the evening by an earthquake that hit Assam. During that period the forest went down and became the lake.Chandubi Lake is a natural lake located in Rabha Hasong Autonomous Council, Kamrup District, Assam.

Q4. When did bank erosion in Majuli begin after an earthquake? Q4. When did bank erosion in Majuli begin after an earthquake?
(A) 1950 (A) 1950
(B) 1988 (B) 1988
(C) 1970 (C) 1970
(D) 1930 (D) 1930
Answer: (A) 1950 Answer: (A) 1950
According to available information, significant bank erosion in Majuli, Assam, began after the major earthquake of 1950. This earthquake caused substantial changes in the Brahmaputra riverbed, leading to increased erosion of the island's banks.According to available information, significant bank erosion in Majuli, Assam, began after the major earthquake of 1950.

Q6. What is the term for the process by which the Earth's plates move and change, causing earthquakes, volcanoes, and the creation of mountain ranges? Q6. What is the term for the process by which the Earth's plates move and change, causing earthquakes, volcanoes, and the creation of mountain ranges?
(A) Continental drift (A) Continental drift
(B) Plate tectonics (B) Plate tectonics
(C) Weathering and erosion (C) Weathering and erosion
Plate tectonics is the theory that the Earth's outer layer is divided into large plates that move relative to each other, creating and destroying landforms, oceans, and continents over millions of years.Plate tectonics is the theory that the Earth's outer layer is divided into large plates that move relative to each other, creating and destroying landforms, oceans, and continents over millions of years.
