Weather and Climate - 1 Class 5 Worksheet SST

Q1: Multiple Choice Questions (MCQs)

Weather is the condition of the atmosphere in a specific place over a short time. It includes things like temperature, humidity, precipitation (rain, snow, etc.), air pressure, wind, and cloud cover.

(ii) The Sun’s rays fall directly on the areas near the
(a) North Pole
(b) South Pole
(c) Equator
(d) Antarctic Circle
Ans: (c)

The Sun’s rays fall directly on the Equator because it is the widest part of the Earth, positioned halfway between the North and South Poles. This direct sunlight makes equatorial regions warmer and results in consistent day lengths throughout the year.

(iii) The water vapour or moisture present in the air is called
(a) rain
(b) cloud
(c) humidity
(d) dew
Ans: (c)

The amount of water vapour in the air is called humidity. The amount of water vapor in the air as compared with the amount of water that the air could hold is called humidity.

(iv) It is hot and humid throughout the year in the
(a) Temperate Zone
(b) Torrid Zone
(c) Frigid Zone
(d) mountains
Ans: (a)

The Torrid Zone is the region located near the Equator, where it is hot and humid throughout the year. This zone experiences high temperatures and significant rainfall, making it a tropical climate.

Q2: Fill in the blanks

(ii) The rays of the Sun become__________as one moves away from the Equator.
Ans: The rays of the Sun become slanting as one moves away from the Equator.

(iii) The__________Zones remain cold all year round.
Ans: The Frigid Zones remain cold all year round.

(iv) The world is divided into__________major climatic regions.
Ans: The world is divided into five major climatic regions.

(v) Places near the coast have a__________climate.
Ans: Places near the coast have a moderate climate.

EduRev Tips:

• Climate refers to the average weather conditions (like temperature and rainfall) of a region observed over many years, while weather describes the day-to-day conditions.
• The sun rays fall almost straight at the equator while they fall slanting as we move away from the equator towards the poles.
• Frigid zones, located near the North and South Poles, are characterized by extremely low temperatures, with ice and snow covering the land for most of the year.
• World climates are generally divided into five large regions: tropical, dry, mid-latitude, high latitude, and highland.
• Coastal areas have a moderate climate because oceans and seas absorb heat and keep temperatures steady, making summers cooler and winters warmer.

Q3: Answer these questions.

(ii) Why does Chennai have a moderate climate?
Ans: While Chennai is in the Torrid Zone and close to the equator, its climate remains moderate due to the influence of coastal breezes and seasonal rainfall.

(iii) Describe the climatic conditions of each heat zone.
Ans: Heat zones are the different zones of the earth, where the sun's rays fall differently, thus causing different climate patterns. These zones are called the Torrid Zone, the two Temperate Zones, and the two Frigid Zones. 
1. The Torrid Zone is very hot since the sun shines overhead here. 
2. The Temperate Zones maintain a moderate climate.
3. The Frigid Zones are extremely cold.

(iv) Write the difference between
(a) weather and climate.
Ans: 

(b) moderate climate and extreme climate.
Ans: 

• In moderate climate, it is neither too hot in summer nor cold in winter. In extreme climates, the summers are too hot and the winters are too cold.
• The annual and average range of temperature is low in moderate climates and more in extreme climates.
• Moderate temperatures are generally found in coastal areas, whereas extreme temperatures are generally found in inland areas.
• An example of a moderate-temperature city is Chennai and that of an extreme-climate city is Delhi.

(v) How do winds influence the climate of a place?
Ans: The winds affect the climate because they create the way hot and cold air is moved around. Wind currents can push warm or cold air in the direction of the currents. They can even push storms in the direction the current is flowing. The wind movement also influences the climate of a particular place.
