9. apart from nimbus, which other clouds are gret in color
10. Three of the following are done during dry weather apart from one. which one is it?
11. What causes rain?
Rain is formed when water vapor in the air cools and condenses into droplets that become heavy enough to fall from the clouds.
12. What is the name of the visible layer of the sun's atmosphere during a solar eclipse?
The photosphere is the visible layer of the sun's atmosphere and can be seen during a solar eclipse when the moon blocks out the sun.
13. What is a rainbow caused by?
A rainbow is caused by sunlight being refracted, or bent, as it passes through raindrops in the air, separating the light into its colors.
14. What are cirrus clouds made of?
Cirrus clouds are thin, wispy clouds that are made of ice crystals at high altitudes in the sky.
15. What is the primary source of energy for Earth's weather?
The sun is the primary source of energy for Earth's weather, providing heat and light that drives atmospheric processes.
16. What is the layer of the atmosphere where weather occurs?
The troposphere is the lowest layer of the atmosphere where weather occurs, including clouds, rain, and wind.
17. What causes thunder and lightning during a storm?
Thunder and lightning are caused by electrical charges building up in clouds and being discharged as lightning bolts during a storm.
18. What is the main gas in Earth's atmosphere?
Nitrogen makes up the majority of Earth's atmosphere, with around 78\% of the air being nitrogen gas.
19. What is the name of the process where water leaves the leaves of plants into the atmosphere?
Transpiration is the process where water leaves plant leaves into the atmosphere, similar to how humans sweat to cool down.
20. What causes wind to blow?
Wind is caused by the uneven heating and cooling of the Earth's surface, creating differences in air pressure that lead to air movement.
21. What causes the seasons on Earth?
The seasons are caused by the tilt of the Earth's axis. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year.
22. What is the name of the layer of the Earth's atmosphere where weather occurs?
The Troposphere is the layer of the Earth's atmosphere where weather occurs. It is the layer closest to the Earth's surface.
23. Which of the following is not a type of cloud?
Fahrenheit is a unit of temperature measurement, not a type of cloud. Stratus, Cirrus, and Cumulus are all types of clouds.
24. What is the process by which water vapor turns into liquid water?
Condensation is the process by which water vapor turns into liquid water. This is commonly seen when clouds form in the sky.
25. Which of the following is associated with wind speed?
An anemometer is a device used to measure wind speed. It typically consists of cups that rotate in the wind and are used to calculate wind speed.
26. What causes lightning during a thunderstorm?
Lightning is caused by the buildup of static electricity in the atmosphere during a thunderstorm. This static electricity is discharged as a lightning bolt.
27. What is a rainbow caused by?
A rainbow is caused by sunlight being refracted, reflected, and dispersed in water droplets in the atmosphere. This creates the beautiful array of colors that we see.
28. What is the name of the layer of the Earth's atmosphere that contains the ozone layer?
The Stratosphere is the layer of the Earth's atmosphere that contains the ozone layer. The ozone layer helps protect the Earth from harmful ultraviolet radiation.
29. What is the name of the visible part of the sun during a solar eclipse?
The corona is the visible outermost part of the sun's atmosphere during a solar eclipse. It appears as a glowing ring around the darkened sun.
30. Which of the following is not a type of precipitation?
Breeze is not a type of precipitation. Rain, snow, and sleet are all forms of precipitation that occur when water droplets or ice crystals fall from clouds.
31. What causes rainbows to appear in the sky?
Rainbows appear in the sky due to the refraction of light, where sunlight is split into its different colors as it passes through raindrops.
32. Which is the hottest planet in our solar system?
Venus is the hottest planet in our solar system due to its thick atmosphere that traps heat, making it hotter than even Mercury, the closest planet to the sun.
33. What is the name for a visible mass of condensed water droplets or ice crystals suspended in the atmosphere?
A cloud is a visible mass of condensed water droplets or ice crystals suspended in the atmosphere. Fog is a similar phenomenon but occurs close to the ground.
34. What is the main source of energy for the earth's weather system?
The main source of energy for the earth's weather system is sunlight, as it drives processes such as evaporation, wind, and the water cycle.
35. What is the name for a rotating column of air in contact with both the surface of the Earth and a cumulonimbus cloud?
A tornado is a rotating column of air in contact with both the surface of the Earth and a cumulonimbus cloud, often causing destructive winds.
36. Which natural disaster is characterized by a sudden and violent shaking of the ground?
An earthquake is characterized by a sudden and violent shaking of the ground, often caused by movements in the Earth's tectonic plates.
37. What is the name of the layer of gas surrounding a planet or other celestial body?
The layer of gas surrounding a planet or other celestial body is called the atmosphere, which plays a crucial role in regulating temperature and weather patterns.
38. Which celestial body is known as the Red Planet?
Mars is known as the Red Planet due to its reddish appearance, caused by iron oxide (rust) on its surface.
39. What is the name for the path of a celestial body as it moves around another celestial body in space?
The path of a celestial body as it moves around another celestial body in space is called an orbit, which is usually an elliptical shape.
40. Which is the furthest planet from the sun in our solar system?
Neptune is the furthest planet from the sun in our solar system, located beyond Uranus and known for its bluish color.
