1.
Water that falls in drops from clouds.
Correct Answer
B. Rain
Explanation
Rain is the correct answer because it refers to water falling in drops from clouds. Snow is frozen precipitation in the form of ice crystals, sleet is a mixture of rain and snow, and hail is balls of ice that form in thunderstorms. Therefore, rain is the most accurate description of water falling from clouds in droplet form.
2.
Weather that falls as frozen or partly frozen raindrops.
Correct Answer
B. Sleet
Explanation
Sleet is the correct answer because it refers to weather that falls as frozen or partly frozen raindrops. It is a type of precipitation that consists of small ice pellets formed when raindrops freeze before reaching the ground. Sleet is different from hail, which is larger and forms in thunderstorms, and from rain, which falls as liquid water.
3.
To change from a liquid to a solid.
Correct Answer
A. Freeze
Explanation
When a substance changes from a liquid to a solid, it is called freezing. This process occurs when the temperature of the substance drops below its freezing point, causing the particles to slow down and come closer together, forming a solid structure. Therefore, the correct answer is "freeze".
4.
Ice that falls from clouds.
Correct Answer
D. Snow
Explanation
Snow is the correct answer because it is the only option that describes ice falling from clouds. Rain is liquid water falling from clouds, sleet is a mixture of rain and snow, and hail is formed by layers of ice in thunderstorms. Snow, on the other hand, is formed when water vapor freezes in the clouds and falls as ice crystals.
5.
To change from a solid to a liquid.
Correct Answer
A. Melt
Explanation
The term "melt" refers to the process of changing a solid substance into a liquid state. When a substance is heated, the energy causes the particles to gain enough kinetic energy to overcome the attractive forces holding them together, resulting in the solid substance melting and becoming a liquid. Therefore, "melt" is the correct answer as it accurately describes the transformation from a solid to a liquid.
6.
Round ice and hard scow that falls during thunderstorms.
Correct Answer
C. Hail
Explanation
Hail is the correct answer because it is a type of round ice and hard scow that falls during thunderstorms. Hail forms when there are strong updrafts in a thunderstorm that carry raindrops upward into extremely cold areas of the atmosphere. These raindrops freeze into ice pellets, and as they are carried by the updrafts, they can collide with supercooled water droplets, causing them to freeze and grow larger. Eventually, the hailstones become too heavy for the updrafts to support, and they fall to the ground.
7.
Ice will melt when it is warm.
Correct Answer
A. True
Explanation
When the temperature of ice increases, it absorbs heat from the surroundings, causing the ice to melt and turn into water. This is a known physical property of ice, and it occurs because the heat energy breaks the bonds between the water molecules, causing them to move more freely and transition into a liquid state. Therefore, it is correct to say that ice will melt when it is warm.
8.
Water will melt when it is cold.
Correct Answer
B. False
Explanation
Water will not melt when it is cold because melting refers to the process of changing a solid into a liquid, typically by heating it. Cold temperatures cause water to freeze, not melt.
9.
Hail falls during thunderstorms.
Correct Answer
A. True
Explanation
Hail falls during thunderstorms because it is formed when there are strong updrafts in the storm that carry raindrops upward into extremely cold areas of the atmosphere. These raindrops freeze into ice pellets and can grow larger as they are carried by the updrafts, eventually falling to the ground as hailstones. Therefore, it is true that hail falls during thunderstorms.
10.
_________ is wet and clear.
Correct Answer
rain
Explanation
Rain is wet and clear because rain is water that falls from the atmosphere in the form of droplets. Water is inherently wet, and when rain falls, it is usually transparent or clear in appearance.
11.
Falling __________ is white and fluffy.
Correct Answer
snow
Explanation
The word "snow" fits the blank in the sentence because snow is commonly associated with being white and fluffy. Snow is a type of precipitation that falls from the sky in the form of ice crystals, and it is often perceived as being soft and fluffy due to its light and delicate texture. Therefore, "snow" is the most appropriate word to complete the sentence.
