• A. Herodotus
• B. Thales of Miletus
• C. Eratosthenes
• D. Plato

Explanation: Eratosthenes, a Greek scholar and mathematician, is generally credited with coining the term geography. He also made an early calculation of Earth’s circumference.

702. There are ______ themes in geography.

• A. Three
• B. Four
• C. Five
• D. Seven

Explanation: The commonly taught five themes of geography are location, place, human-environment interaction, movement, and region. These themes provide a framework for organizing geographical study.

703. The earth surface & crust constantly evolving due to ?

• A. Rotary cycle
• B. Normal cycle
• C. Rock cycle
• D. Change cycle

Explanation: The rock cycle describes the continuous formation, breakdown, and transformation of rocks through processes such as melting, cooling, weathering, and pressure. It helps explain why Earth’s crust is constantly changing.

704. Which type of climates of world has dry summer & wet winter ?

• A. Western European type
• B. Mediterranean type
• C. Equatorial type
• D. Tundra type

Explanation: The Mediterranean climate has hot, dry summers and mild, wet winters, largely because seasonal wind belts shift over the region. The other listed climate types do not have this characteristic pattern.

705. Sedimentary rocks are formed by natural process known as ?

• A. Lithification
• B. Rejuvenation
• C. Hydration
• D. Peroxidation

Explanation: Lithification is the process by which deposited sediments become solid rock through compaction and cementation. The other terms do not describe sedimentary-rock formation.

706. Atmospheric pressure decrease rapidly with altitude because the air becomes_______ ?

• A. Colder
• B. Less denser
• C. Rich in Ozone
• D. Warmer

Explanation: Air pressure falls with altitude because the air becomes less dense and the weight of the air column above decreases. Cooling or ozone enrichment is not the main reason.

707. When did Amnesty International won the Noble Prize:

• A. 1917
• B. 1967
• C. 1977
• D. 1987Educational Resources

708. A point directly below the sesmic focus is?

• A. Cleft
• B. Epicentre
• C. Incentre
• D. Orthocentre

Explanation: The epicentre is the point on Earth’s surface directly above the seismic focus, where an earthquake begins underground. The other terms are geometrical centres or unrelated terms.

709. The lowest temperature ever recorded on the Earth is?

• A. -89.2 °C
• B. -86.2 °C
• C. -83.2 °C
• D. -92.2 °C

Explanation: The officially recognised lowest air temperature recorded at Earth’s surface is −89.2 °C at Vostok Station, Antarctica, on 21 July 1983. Satellite measurements have found colder surface temperatures, but this is the standard weather-record value.

710. The process by which air flows from one location in the atmosphere to another is called __________?

• A. Convection
• B. Radiation
• C. Conduction
• D. Electromagnetic Induction

Explanation: Atmospheric air moves because unequal heating creates density differences and convection currents. Radiation transfers energy, while conduction transfers heat through contact rather than moving air from place to place.
