Answer: Pre-monsoon showers
Coffee Blossom Showers are pre-monsoon rainfall in Karnataka during March-April that help in coffee flowering. These showers are caused by convective activity and moisture from the Arabian Sea. They are crucial for Karnataka's coffee industry, which produces about 70% of India's coffee.
Which process forms an 'esker'?
- River deposition
- Glacial deposition
- Wind deposition
- Coastal deposition
Answer: Glacial deposition
Eskers are long, winding ridges of sand and gravel deposited by meltwater streams flowing within or under glaciers. They indicate former ice flow directions. Eskers are common in Scandinavia, Canada, and parts of North America.
Which river is known as the 'Lifeline of Haryana'?
- Yamuna

- Sutlej
- Markanda
Answer: Yamuna
The Yamuna River is called the 'Lifeline of Haryana' as it provides water for irrigation, drinking, and industry through the Western Yamuna Canal. The river supports agriculture in the fertile plains of Haryana and Delhi.
Which phenomenon causes 'Tea Showers' in Assam?
- Northeast Monsoon
- Pre-monsoon showers
- Western Disturbances
- Retreating Monsoon
Answer: Pre-monsoon showers
Tea Showers are pre-monsoon rainfall in Assam during March-April that help in tea leaf growth. These showers are caused by convective activity and moisture from the Bay of Bengal. They are crucial for Assam's tea industry, which produces about 50% of India's tea.
Which process forms a 'drumlin'?
- River deposition
- Glacial deposition
- Wind deposition
- Coastal deposition
Answer: Glacial deposition
Drumlins are elongated hills of glacial till deposited by moving ice sheets. They have a steep stoss side and gentle lee side, indicating ice flow direction. Drumlins are common in Ireland, Canada, and parts of North America.
Which river is known as the 'Lifeline of Bihar'?
- Ganga
- Kosi
- Gandak
- Son
Answer: Ganga
The Ganga River is called the 'Lifeline of Bihar' as it provides water for irrigation, drinking, and transport. The river supports agriculture in the fertile Gangetic plains and is culturally significant. Major cities like Patna are located on its banks.
Which factor causes 'Kumkum Showers' in Karnataka?
- Northeast Monsoon
- Pre-monsoon showers
- Western Disturbances
- Retreating Monsoon
Answer: Pre-monsoon showers
Kumkum Showers are pre-monsoon rainfall in Karnataka during March-April that help in coffee flowering. These showers are caused by convective activity and moisture from the Arabian Sea. They are crucial for the state's plantation economy.
Which process forms a 'fjord'?
- River erosion
- Glacial erosion
- Wind erosion
- Coastal erosion
Answer: Glacial erosion
Fjords are deep, narrow inlets with steep sides formed by glacial erosion. When glaciers retreat, seawater floods the U-shaped valley. Fjords are common in Norway, Chile, and New Zealand. They are distinct from rias, which are drowned river valleys.
Which river is known as the 'Lifeline of Telangana'?
- Godavari
- Krishna
- Manjira
- Pranhita
Answer: Godavari
The Godavari River is called the 'Lifeline of Telangana' as it provides water for irrigation, drinking, and industry through projects like the Kaleshwaram Lift Irrigation Scheme. The river supports agriculture in the drought-prone regions of Telangana.
Which phenomenon causes 'Amphan' cyclones in the Bay of Bengal?
- Warm sea surface temperatures
- Low wind shear
- High humidity
- All of these
Answer: All of these
Cyclones like Amphan form in the Bay of Bengal due to warm sea surface temperatures (>26.5°C), low vertical wind shear, and high humidity. These conditions provide energy for cyclone development. Climate change may increase cyclone intensity.
Which landform is created by wave erosion?
- Sea Arch
- Sandbar
- Spit
- Tombolo
Answer: Sea Arch
Sea arches are formed by wave erosion attacking weaknesses in coastal cliffs. When the arch collapses, it forms a sea stack. Sandbars, spits, and tombolos are depositional landforms created by longshore drift.
Which climate type has hot summers, cold winters, and moderate rainfall?
- Continental
- Mediterranean
- Monsoon
- Equatorial
Answer: Continental
Continental climate is characterized by hot summers, cold winters, and moderate rainfall (30-100 cm annually). Found in interior regions of continents like Central Asia, North America, and Eastern Europe. Supports temperate grasslands and deciduous forests.
Which Indian state is the largest producer of copper?
- Jharkhand
- Rajasthan
- Madhya Pradesh
- Andhra Pradesh
Answer: Madhya Pradesh
Madhya Pradesh is the largest producer of copper in India, primarily from the Malanjkhand mine in Balaghat district. Copper is essential for electrical wiring, electronics, and renewable energy technologies. India imports significant copper to meet domestic demand.
Which type of plate boundary causes transform faults?
- Convergent
- Divergent
- Transform
- Passive
Answer: Transform
Transform plate boundaries occur where tectonic plates slide horizontally past each other, causing transform faults. The San Andreas Fault in California is a classic example. These boundaries cause earthquakes but not volcanoes or mountain building.

Answer: Western Disturbances
Mavath rainfall in Rajasthan occurs during winter (December-February) due to Western Disturbances originating in the Mediterranean. This rainfall is crucial for Rabi crops like wheat and mustard in the arid regions of North-West India.
Which process forms a 'cirque'?
- River erosion
- Glacial erosion
- Wind erosion
- Coastal erosion
Answer: Glacial erosion
A cirque is a bowl-shaped depression formed by glacial erosion at the head of a valley glacier. It has steep walls and may contain a tarn (small lake) after the glacier melts. Cirques are common in the Himalayas and Alps.
