Which landform is created by wind erosion in deserts?
- Moraine
- Yardang
- Eskers
- Drumlin
Answer: Yardang
Yardangs are streamlined ridges carved by wind erosion in arid regions. They form parallel to prevailing winds and are common in deserts like the Sahara and Thar. Moraines, eskers, and drumlins are glacial landforms.
Which climate type is characterized by dry summers and wet winters?
- Tropical Monsoon
- Mediterranean
- Equatorial
- Continental
Answer: Mediterranean
Mediterranean climate is characterized by hot, dry summers and mild, wet winters. It is found around the Mediterranean Sea, California, central Chile, South Africa's Cape region, and southwestern Australia. Suitable for olives, grapes, and citrus.
Which Indian state is the largest producer of mica?
- Jharkhand
- Andhra Pradesh
- Rajasthan
- Odisha
Answer: Andhra Pradesh
Andhra Pradesh is the largest producer of mica in India, particularly from the Nellore district. Mica is used in electrical and electronic industries due to its insulating properties. India is among the top mica producers globally.
Which type of volcano is Mount Fuji in Japan?
- Shield Volcano
- Composite Volcano
- Cinder Cone
- Caldera
Answer: Composite Volcano
Mount Fuji is a composite (stratovolcano) formed by layers of lava, ash, and volcanic rocks. It last erupted in 1707 and is considered active but dormant. Composite volcanoes are characterized by steep slopes and explosive eruptions.
Which river is known as the 'Lifeline of Madhya Pradesh'?
- Chambal
- Narmada
- Tapti
- Son
Answer: Narmada
The Narmada River is known as the 'Lifeline of Madhya Pradesh' as it flows through the heart of the state, providing water for irrigation, drinking, and hydropower. Major projects include Indira Sagar and Omkareshwar dams. The river is also culturally significant.
Which factor causes the 'break' in the Indian Monsoon?
- Shift of monsoon trough
- Western Disturbances
- El Niño
- All of these
Answer: All of these
A 'break' in the Indian Monsoon (period of reduced rainfall) can be caused by: shift of monsoon trough northwards, influence of Western Disturbances, or El Niño conditions. Breaks are critical for agriculture as they affect crop growth stages.
Which process is responsible for the formation of metamorphic rocks?
- Cooling of lava
- Deposition of sediments
- Heat and pressure
- Volcanic eruption
Answer: Heat and pressure
Metamorphic rocks form when existing rocks (igneous, sedimentary, or other metamorphic) are subjected to high heat and pressure without melting. This changes their mineral composition and texture. Examples: marble (from limestone), slate (from shale).
Which river is known as the 'Tsangpo' before entering India?
- Indus
- Brahmaputra
- Sutlej
- Karnali
Answer: Brahmaputra
The Brahmaputra River is known as 'Yarlung Tsangpo' in Tibet before entering India through Arunachal Pradesh. It flows through Tibet, India, and Bangladesh, covering about 2,900 km. In Bangladesh, it merges with the Ganga to form the Padma River.
What is the primary cause of the Indian Monsoon?
- Differential heating of land and sea
- Earth's rotation
- Ocean currents
- Volcanic activity
Answer: Differential heating of land and sea
The Indian Monsoon is primarily caused by differential heating of the Indian landmass and the Indian Ocean. In summer, land heats faster, creating low pressure that draws moist winds from the ocean. In winter, the reverse occurs, causing dry Northeast Monsoon.
Which layer of Earth is responsible for its magnetic field?
- Crust
- Mantle
- Outer Core
- Inner Core
Answer: Outer Core
The Earth's magnetic field is generated by the motion of molten iron and nickel in the outer core, a process called the geodynamo. This magnetic field protects Earth from solar wind and cosmic radiation, and enables compass navigation.
Which river is known as the 'Vridha Ganga'?
- Krishna
- Godavari
- Mahanadi
- Narmada
Answer: Godavari
The Godavari River is called 'Vridha Ganga' (Old Ganga) due to its large size, age, and religious significance among peninsular rivers. It is the second-longest river in India and supports agriculture, hydropower, and biodiversity across multiple states.
Which factor primarily determines the climate of a place?
- Latitude
- Longitude
- Altitude
- All of these
Answer: All of these
Climate is determined by multiple factors: latitude (distance from equator), altitude (height above sea level), distance from sea, ocean currents, wind patterns, and topography. These factors interact to create regional climate variations.
Which process forms sedimentary rocks?
- Cooling of magma
- Heat and pressure
- Deposition and compaction
- Volcanic eruption
Answer: Deposition and compaction
Sedimentary rocks form through deposition, compaction, and cementation of sediments like sand, silt, and organic matter. Examples include sandstone, limestone, and shale. They often contain fossils and are found in layers (strata).
Which river forms the Dhuandhar Falls?
- Chambal
- Narmada
- Tapti
- Son
Answer: Narmada
The Dhuandhar Falls are formed by the Narmada River near Jabalpur in Madhya Pradesh. The name means 'smoke cascade' due to the mist created by the falling water. The falls are about 30 meters high and a popular tourist attraction.
What is the average annual rainfall in India?
- 800 mm
- 1,100 mm
- 1,500 mm
- 2,000 mm
Answer: 1,100 mm
India's average annual rainfall is approximately 1,100 mm, but distribution is highly uneven. Mawsynram receives over 11,000 mm, while Jaisalmer gets less than 200 mm. The Southwest Monsoon contributes about 75% of the annual rainfall.
Which plate boundary type causes mountain building?
- Divergent
- Convergent
- Transform
- Passive
Answer: Convergent
Convergent plate boundaries, where two tectonic plates collide, cause mountain building (orogeny). The Himalayas formed from the convergence of the Indian and Eurasian plates. Divergent boundaries create rift valleys, while transform boundaries cause earthquakes.
What is the primary cause of La Niña?
- Warming of Eastern Pacific
- Cooling of Eastern Pacific
- Warming of Indian Ocean
- Cooling of Atlantic Ocean
Answer: Cooling of Eastern Pacific
La Niña is characterized by the unusual cooling of surface waters in the eastern tropical Pacific Ocean. It is the opposite of El Niño. La Niña often brings above-average monsoon rainfall to India and drought conditions to the western coast of South America.
Which Indian state is the largest producer of manganese?
- Madhya Pradesh
- Odisha
- Maharashtra
- Karnataka
Answer: Madhya Pradesh
Madhya Pradesh is the largest producer of manganese in India, contributing about 30% of national production. Major deposits are in Balaghat, Chhindwara, and Jhabua districts. Manganese is essential for steel production and battery manufacturing.
What is the approximate thickness of the Earth's crust under continents?
- 5-10 km
- 20-30 km
- 30-50 km
- 70-100 km
Answer: 30-50 km
The continental crust is approximately 30-50 km thick, while oceanic crust is thinner (5-10 km). The crust is the outermost solid shell of Earth, composed mainly of granitic rocks on continents and basaltic rocks under oceans.
Which monsoon brings rainfall to most of India?
- Northeast Monsoon
- Southwest Monsoon
- Western Disturbances
- Retreating Monsoon
Answer: Southwest Monsoon
The Southwest Monsoon (June-September) brings about 75% of India's annual rainfall. It originates from the Indian Ocean and splits into Arabian Sea and Bay of Bengal branches. The timing and distribution of this monsoon are critical for Indian agriculture.
