IIT JAM Geology Syllabus 2025 FAQs
What is the origin of the Solar System and Earth?
The Solar System formed about 4.6 billion years ago from a giant molecular cloud. Over time, gravitational forces caused particles to accrete, forming planets like Earth.
How is the Earth’s geosphere defined?
The geosphere refers to the solid Earth, including the crust, mantle, and core. It encompasses the rocks, minerals, and structures that compose the planet’s lithosphere.
What is the shape and size of the Earth?
Earth is an oblate spheroid, meaning it is mostly spherical but slightly flattened at the poles and bulging at the equator due to its rotation.
How does the Earth-Moon system influence geological processes?
The Moon’s gravitational pull affects Earth’s tides and stabilizes its axial tilt, influencing climate and ocean currents. It also contributes to Earth’s rotational dynamics.
How do scientists date rocks and determine the age of the Earth?
Radiometric dating techniques measure the decay of radioactive elements in rocks to determine their age. This data, combined with geological evidence, helps estimate Earth’s age at approximately 4.5 billion years.
What are volcanism and volcanic landforms?
Volcanism is the process of magma and gases erupting onto the Earth’s surface. Volcanic landforms include mountains (volcanoes), calderas, lava plateaus, and volcanic islands.
What is the interior structure of the Earth like?
The Earth’s interior is divided into the crust (continental and oceanic), mantle (upper and lower), and core (outer liquid and inner solid). These layers have different compositions and temperatures.
How do earthquakes occur and what are their geological implications?
Earthquakes result from the sudden release of energy in the Earth’s crust, often along faults. They can cause ground shaking, tsunamis, and significant geological changes over time.
What is Earth’s magnetism and how does it influence geological processes?
Earth’s magnetic field is generated by molten iron in its outer core. It shields the planet from solar winds and influences navigation systems, as well as the behaviour of magnetic minerals in rocks.
What are Plate Tectonics and their significance in geology?
Plate Tectonics is the theory explaining the movement of Earth’s lithospheric plates. It accounts for continental drift, mountain formation (orogeny), earthquakes, volcanic activity, and the distribution of geological features on Earth’s surface.
