All questions of Weather for Grade 2 Exam

Frozen dew is called
  • a)
    hail stone
  • b)
    rain
  • c)
    frost
  • d)
    water
Correct answer is option 'C'. Can you explain this answer?

Shivam Mehra answered
Explanation:

Definition of Frozen Dew: Frozen dew is a type of frost that forms when the temperature drops below freezing and there is moisture in the air. The moisture in the air freezes onto surfaces, forming small ice crystals.

Reason for calling it Frost: Frozen dew is called frost because it is a type of frost that forms on surfaces. It is different from other forms of precipitation like rain, which is liquid water, or hailstones, which are chunks of ice that fall from the sky.

Formation of Frozen Dew: Frozen dew forms when the temperature drops below freezing and there is moisture in the air. The moisture in the air freezes onto surfaces, forming small ice crystals. This can happen overnight when the temperature drops and the air is humid.

Features of Frozen Dew: Frozen dew appears as small, white crystals on surfaces like grass, leaves, and cars. It can be slippery and dangerous to walk on because it creates a thin layer of ice on surfaces.

Conclusion: Frozen dew is a type of frost that forms when the temperature drops below freezing and there is moisture in the air. It is different from other forms of precipitation like rain or hailstones. It appears as small, white crystals on surfaces and can be slippery and dangerous to walk on.

State whether the following statement is True or False:
Humid weather is when there is a lot of water vapor in the air, making it difficult for sweat to evaporate quickly.
  • a)
    True
  • b)
    False
Correct answer is option 'A'. Can you explain this answer?

Understanding Humid Weather
Humid weather refers to the condition when the air contains a high amount of water vapor. This can significantly affect how we feel and our body's natural cooling mechanisms.
What is Humidity?
- Humidity is the measure of the amount of moisture in the air.
- When the humidity level is high, it means there is a lot of water vapor present.
Impact on Sweat Evaporation
- Sweat is the body's natural way of cooling down.
- Under normal conditions, sweat evaporates quickly, taking heat away from the body.
Why Humidity Affects Evaporation
- In humid conditions, the air is already saturated with moisture.
- When sweat is produced, it struggles to evaporate because the air cannot hold much more water vapor.
- As a result, the cooling effect from sweat is reduced, leading to a feeling of discomfort and increased body temperature.
Conclusion
The statement that humid weather makes it difficult for sweat to evaporate quickly is true. High humidity levels impede the evaporation process, which is crucial for effective temperature regulation in the body. Thus, option 'A' is correct.
Understanding these concepts can help us better prepare for and cope with humid weather conditions.

State whether the following statement is True or False.
Water covers about 71% of the earth's surface.
  • a)
    True
  • b)
    False
Correct answer is option 'A'. Can you explain this answer?

Riya Singh answered
  • In easy words, this means that most of the earth is covered by water.
  • It is like a big blanket of water around the land. This water can be found in rivers, seas, ponds, lakes, and even in the form of ice and glaciers.
  • So, the statement is True because water does cover a large part of the earth's surface.

What effect does a sea breeze have on coastal areas during the day?
  • a)
    It warms up the land
  • b)
    It cools down the land
  • c)
    It has no effect
  • d)
    It causes rain
Correct answer is option 'B'. Can you explain this answer?

Understanding Sea Breezes
A sea breeze is a natural phenomenon that occurs along coastal areas during the day. It plays a significant role in influencing local temperatures and weather patterns.
How Sea Breezes Form
- During the day, the sun heats the land faster than the water.
- As the land warms up, the air above it also heats up and rises.
- Cooler air from the sea then moves in to replace the rising warm air, creating a breeze from the sea towards the land.
Effect on Coastal Areas
- The movement of cooler air from the sea helps to cool down the land.
- As the sea breeze blows inland, it lowers the temperature, making the coastal area more comfortable during hot days.
- This cooling effect can help reduce the risk of overheating in urban areas near the coast.
Benefits of Sea Breezes
- Sea breezes can bring relief from heat, especially in summer months.
- They contribute to a pleasant climate for beachgoers and residents.
- They can also impact local weather patterns, sometimes leading to increased cloud cover and even precipitation later in the day.
In summary, the correct answer to the question is option 'B': Sea breezes cool down the land by bringing in cooler air from the sea, creating a refreshing atmosphere along coastal areas during the day.

Water changes from one state to another due to _____ and cooling.
  • a)
    heating
  • b)
    freezing
  • c)
    evaporation
  • d)
    melting
Correct answer is option 'C'. Can you explain this answer?

Water changes from one state to another due to heating and cooling. When water is heated, it can change from a liquid to a gas (vapour) through a process called evaporation.

Which of these falls in different shapes?
  • a)
    Hailstone
  • b)
    Fog
  • c)
    Dew
  • d)
    Snowflakes
Correct answer is option 'D'. Can you explain this answer?

Rahul Kumar answered
Snowflakes are formed by the crystallization of water vapor in the atmosphere, and they have a wide variety of shapes and patterns. Each snowflake is unique and can have a complex structure, often described as having different shapes. In contrast, hailstones are typically spherical, although they can vary in size depending on atmospheric conditions.

What happens when the sun heats the water on the earth's surface?
  • a)
    The water freezes into ice
  • b)
    The water turns into clouds
  • c)
    The water evaporates and rises into the air
  • d)
    The water turns into solid rocks
Correct answer is option 'C'. Can you explain this answer?

  • When the sun heats the water on the earth's surface, it starts to evaporate and rise up into the air. This process is like when you put a wet cloth in the sun and it dries up.
  • The water turns into tiny water droplets in the air, forming clouds. This is how the water cycle begins, where water moves from the earth into the air and back again as rain or snow.
