Explanation

• Pakistan’s geo-strategic importance comes from its location at the crossroads of South Asia, Central Asia, and the Middle East.

• It provides access to warm waters through the Arabian Sea.

• It connects landlocked Central Asian countries with global trade routes.

• Its location makes it important for regional trade, security, and energy routes.

• Major international projects like CPEC highlight this importance.

Explanation

• The Balochistan Plateau is least suitable for intensive agriculture due to dry climate and low rainfall.

• It has arid (خشک) conditions and limited water resources.

• Soil is mostly rocky and less fertile compared to plains.

Explanation

• Seasonal rainfall in Pakistan is mainly controlled by the monsoon system.

• Monsoon winds bring moist air from the Indian Ocean during summer (July–September).

• These winds cause heavy rainfall in many parts of Pakistan.

• In winter, dry continental winds reduce rainfall.

• This seasonal wind pattern creates variation in rainfall throughout the year.

Explanation

• A quantum of energy of light (electromagnetic radiation) is called a photon.

• Photon is the smallest discrete packet (bundle) of energy.

• It carries energy proportional to its frequency (E = hf).

• Photons have no mass and travel at the speed of light.

• Light shows particle nature due to photons.

Explanation

• Photoelectric emission stops when the frequency of incident light is below the threshold frequency of the metal.

• Below this minimum frequency, electrons cannot gain enough energy to escape the metal surface.

• Each metal has its own threshold frequency.

• This effect supports the quantum theory of light.

• The gravitational pull of the Moon and Sun combines, producing very high and very low tides.

• Spring tides are not related to seasons like spring; the name refers to “jumping or rising” tides.

• They occur about twice a month.
