Geology FAQs

1. What is the difference between igneous and sedimentary rocks ?
Ans. Igneous rocks form when molten magma cools and solidifies, either beneath Earth's surface or above it, while sedimentary rocks develop from compressed and cemented fragments of weathered rocks and minerals. Igneous rocks are typically harder and denser, whereas sedimentary rocks often contain visible layers and fossils, making them valuable for understanding Earth's history.
2. How do tectonic plates move and what causes earthquakes ?
Ans. Tectonic plates drift across Earth's lithosphere due to convection currents in the mantle, moving at rates of centimetres per year. When plates collide, slide past each other, or pull apart at plate boundaries, stress builds up along faults. The sudden release of this accumulated energy creates seismic waves, producing earthquakes that shake the ground and can cause significant surface damage.
3. What are the main types of minerals and how do you identify them ?
Ans. Minerals are naturally occurring, inorganic solids with a crystalline structure and fixed composition, classified by properties like silicates, oxides, carbonates, and halides. Students identify minerals using hardness tests, colour, streak, luster, cleavage patterns, and crystal form. The Mohs hardness scale helps compare mineral durability, while specific gravity indicates density relative to water.
4. Why does weathering and erosion happen and what's the difference ?
Ans. Weathering breaks down rocks and minerals in place through chemical reactions, temperature changes, and biological processes, while erosion transports these weathered materials elsewhere via water, wind, or ice. Mechanical weathering fragments rock without altering its composition; chemical weathering alters mineral structure. Both processes fundamentally reshape landscapes and create soil over geological timescales.
5. What causes volcanoes to erupt and what are the different types ?
Ans. Volcanic eruptions occur when pressure from superheated magma beneath Earth's crust forces molten rock to the surface through weaknesses in the lithosphere. Shield volcanoes produce gentle, flowing lava; stratovolcanoes create explosive eruptions with ash and pyroclastic flows; cinder cones form from small, brief eruptions. Eruption style depends on magma composition, viscosity, and dissolved gas content.
6. How are fossils formed and what can they tell us about Earth's history ?
Ans. Fossils form through permineralisation, replacement, or mould-and-cast processes when organisms become buried in sediment and protected from decay over millions of years. These preserved remains reveal information about extinct species, ancient environments, and evolutionary relationships between organisms. Fossil distribution across rock layers helps geologists establish relative dating and reconstruct prehistoric climates and ecosystems.
7. What is the rock cycle and why do rocks change forms ?
Ans. The rock cycle describes how igneous, sedimentary, and metamorphic rocks transform into one another through geological processes including melting, cooling, weathering, and pressure-heat combinations. Rocks change forms because Earth's internal heat and surface processes continuously recycle crustal material. Understanding this cycle explains why different rock types appear in various locations and how landscapes evolve.
8. What are the layers of Earth and what's each layer made of ?
Ans. Earth consists of a solid crust, liquid outer core, and solid inner core, with a dense, hot mantle sandwiched between. The crust contains continental and oceanic varieties; the mantle comprises hot rock that drives plate motion; the outer core contains liquid iron and nickel generating Earth's magnetic field. These concentric layers have distinct compositions, temperatures, and densities.
9. How do mountains form and what different types exist ?
Ans. Mountains form through plate collision, volcanic activity, or faulting-processes that uplift crustal material above surrounding terrain. Fold mountains develop where plates compress and buckle sedimentary layers; block mountains result from faulting that tilts crustal blocks; volcanic mountains build from successive eruptions. Mountain formation timescales span millions of years and continues reshaping continental landscapes today.
10. What is metamorphism and how do rocks change under heat and pressure ?
Ans. Metamorphism transforms existing rocks into metamorphic varieties through intense heat, pressure, and chemical activity deep within Earth's crust, without melting the rock completely. Regional metamorphism occurs during mountain building; contact metamorphism happens near magma chambers. Original mineral structures rearrange, creating denser crystals and new textures, producing rocks like schist, marble, and slate valuable for construction and decorative uses.
