5th Class Social Studies Unit 5.2 MCQs – Weather and Climate (موسم اور آب و ہوا) | PAKMCQs

The period of time is correct because weather refers to short-term daily atmospheric conditions, while climate is the average pattern over a long period.

Distance from the Equator is correct because it determines the angle at which sunlight strikes the Earth's surface.

High (hot) is correct because equatorial regions receive the most direct solar energy throughout the year.

Because the sunrays fall vertically is correct because vertical rays are more concentrated and spread over a smaller area, producing more heat.

All of the above is correct because Ecuador, Brazil, Kenya, and Indonesia are all located directly along the Equator's line.

Very cold is correct because the polar regions receive very little solar energy and are covered in ice.

Because sunrays fall slantingly is correct because slanted rays are less concentrated and spread over a much larger area, producing less heat.

Both (A) and (B) is correct because Canada, Denmark, and Russia are all high-latitude northern countries located close to the Arctic region.

It decreases is correct because air pressure drops at higher altitudes, causing the atmosphere to hold less heat.

They are higher is correct as mountains rise significantly above the baseline of sea level.

Because they are higher than sea level is correct because greater elevation naturally leads to colder atmospheric conditions and lower temperatures.

Comparatively hot is correct because low-lying plains absorb and retain more heat from the sun compared to high-altitude areas.

Due to difference in altitude (height) is correct because Murree is situated at a high mountainous level, making it much colder than the coastal city of Karachi.

Current is correct because ocean currents are cohesive streams of water moving continuously through the ocean, driven by gravity and wind.

Two types is correct because ocean currents are categorized primarily into warm water currents and cold water currents based on temperature.

Warm and cold water currents are correct as they represent the temperature differences of water masses moving across different regions of the globe.

Gains one hour is correct because warm water releases heat into the air, raising the temperature of nearby lands.

They decrease the temperature is correct because cold water absorbs heat from the air, making the climate of the adjacent coast colder.

They raise the temperature is correct because winds carrying thermal energy from hot zones transfer that warmth to the colder places they blow into.

They decrease the temperature is correct because cold winds bring lower temperatures and a cooling effect to the regions they enter.

They are generally moist is correct because winds crossing large water bodies like oceans absorb moisture through evaporation along the way.

Rainfall is correct because when moist ocean winds rise and cool down, the water vapor condenses into clouds and falls as rain.

Carbon dioxide is correct because plants need this gas to perform photosynthesis and make their own food.

Oxygen is correct because it is produced as a byproduct of photosynthesis, which is essential for the respiration of living things.

It increases carbon dioxide is correct because fewer trees are left to absorb this greenhouse gas from the air, causing it to build up.

All of the above is correct because industries rely heavily on coal, petrol, natural gas, and wood as primary energy sources to power machines.

Increase in carbon dioxide is correct as combustion releases stored carbon from the fuels into the atmosphere as gas.

The amount of carbon dioxide is correct because smoke is mostly made of carbon particles and gases that pollute the clean air.

Carbon dioxide is correct because it acts as a greenhouse gas, trapping the Sun's heat in the atmosphere and raising Earth's temperature.

Atmosphere is correct because it refers to the protective layer of gases surrounding the planet.

Sunrays is correct because these gases are transparent to the incoming shortwave light energy from the sun.

The heat of the Earth is correct because these gases act like a blanket, trapping the thermal energy radiated from the ground.

Temperature increases is correct because the trapped thermal energy naturally warms up the Earth's atmosphere.

Greenhouse Effect is correct because this warming process is similar to how a glass greenhouse keeps plants warm.

Greenhouse Gases is correct as it is the specific scientific name for heat-trapping gases like carbon dioxide and methane.

Global Warming is correct because it describes the long-term, worldwide rise in temperatures caused by human activities.

All of the above is correct because global warming causes glaciers to melt, oceans to rise, and weather patterns to become extreme.

Change in weathers (climate) is correct because global warming disrupts the natural climate balance, leading to unpredictable weather events.

In 2020 is correct as this was the specific year when record-breaking monsoon rainfall flooded the entire city of Karachi.

Heavy floods is correct because the excessive water overwhelmed the drainage systems, causing damage across Karachi.

Great human and financial loss is correct because the floods destroyed homes, businesses, and claimed many precious lives.

Past sixty to seventy years is correct because the 2020 rainfall broke historical weather records of many decades in Karachi.

To plant as many trees as possible is correct because trees absorb carbon dioxide, which is the main gas causing global warming.

Poisonous gases is correct because industrial emissions pollute the air and contribute directly to the greenhouse effect.

Vehicles that emit less smoke is correct as they release fewer pollutants and carbon dioxide into the environment.

Walk on foot is correct because walking instead of driving for short trips saves fuel and prevents vehicle emissions.

Solar and wind energies is correct because these are clean, renewable resources that produce energy without releasing greenhouse gases.

0.03% is correct because this small, natural percentage is the balanced amount of carbon dioxide required to keep the Earth warm without overheating.

It will increase global temperature is correct because more carbon dioxide traps more solar heat, harming life through global warming.

Natural disasters is correct because this term refers to catastrophic events like earthquakes or floods that occur through natural forces.

All of the above is correct because cyclones, floods, droughts, landslides, and earthquakes are all major natural forces that cause devastation.

Because of increase in temperature is correct because hot air expands and rises, creating a low-pressure zone that sucks in surrounding winds.

From high to low pressure areas is correct because air naturally moves from regions of dense, high pressure to fill the empty low-pressure zones.

Rainfalls and snowfalls is correct because cyclones carry huge amounts of moisture from the sea, leading to extreme precipitation.

All of the above is correct because the violent winds and heavy rains of a cyclone destroy infrastructure, block transport, and ruin agriculture.

In oceans is correct because the warm waters of the sea provide the heat and moisture needed for cyclones to form and grow.

Landsliding is correct because it is the specific geomorphic process where gravity pulls loosened mountain soil and rocks downward.

All of the above is correct because gravity, heavy rainfall, and storms can loosen the mountain soil, causing it to slide down.

Routes and highways are blocked is correct because the falling debris and mud cover the roads, stopping transportation.

Earthquake is correct because it is the sudden shaking of the ground caused by the release of energy in the Earth's crust.

Different movements in the internal parts of the Earth is correct because tectonic shifts deep underground release seismic waves that shake the surface.

They travel in all directions is correct because seismic energy spreads outward from the epicenter like ripples in water.

Buildings, bridges, and roads is correct because the intense shaking of the ground breaks the concrete and foundations of infrastructure.

Water, gas, and electricity is correct because underground pipes and power lines break during the ground's violent movements.

Flood is correct because it is the state of water overflowing its normal boundaries onto dry land.

Heavy rains and melting of snow on mountains is correct because these factors release massive volumes of water into the river systems too quickly.

Both (A) and (B) is correct because overflowing water drowns livestock, ruins agricultural fields, and sweeps away houses.

Diseases break out is correct because contaminated water and poor sanitation lead to the rapid spread of waterborne illnesses.
