( )3. What is "cloud seeding"? A. A kind of cloud. B. A chemical. C. A way to make rain. 相关知识点: 试题来源: 解析 C “云播种”是一种通过向云层中播撒特定物质(如干冰、碘化银等)来促进降雨的技术。因此,正确答案是 C,即“一种制造雨水的方法”。
Cloud seeding is done with generators on the ground, via airplane, or with rockets or even cannons. The most common substances used to seed clouds are dry ice and silver iodide. Clouds are made of water droplets and ice crystals that form around bits of dust or salt in the atmosphere. ...
Cloud seeding is the process of spreading chemicals like dry ice to forcefully make clouds undergo precipitation to form frozen ice drops that will defrost & become water droplets as they fall. The seeding is done from the earth or more efficiently by plane. The thing about rain is… As we ...
“While cloud seeding is often described as ‘creating’ rain,” Kuhl wrote, “it can be more accurately described as moving rain from one location to another, and cloud seeding may simply redistribute risk.” She added that the practice of c...
What is cloud seeding? Cloud seeding is the process of spreading either dry ice, or more commonly, silver iodide aerosols, into the upper part of clouds to try to stimulate the precipitation process and form rain. Since most rainfall starts through the growth of ice crystals from super-cooled...
Cloud seeding is a scientific process that improves a cloud’s ability to make rain or snow, as well as control other weather events. The technique, which experts also call weather modification, can really help in areas that don’t have a big enough supply of natural water. After cloud see...
Cloud seeding is a weather modification technique of producing extra snow after precipitation is already occurring. The efficient process involves machines spraying tiny crystals of silver iodide into the atmosphere, which improves a cloud’s ability to make rain or snow. The new ice crystals provide...
Cloud seeding is a method of artificially causing clouds to produce precipitation (降水) in the form of rain or snow.Cloud seeding has also been used in attempts to modify the severity of hail storms and hurricanes.The effectiveness of cloud seeding remains controversial (有争议的).but it conti...
“It is possible that you’re actually stealing water from someone else when you do (cloud seeding), because it may be, at least on a regional basis, a zero-sum game where if water falls out of the cloud in one spot, it’s even drier by the time it makes it downwind to the next...
