Clouds form when humid air cools down enough for water vapor to condense into droplets or ice crystals. The altitude at which this happens depends on many things including the humidity, temperature and elevation. There are 4 types of clouds which are categorised by the height of the base of the cloud from the ground:
High-level clouds, called cirrus clouds, can reach heights of 6,000 meters. They are thin and dont produce rain.
Midlevel clouds, refereed to as "alto-" clouds, form between 2,000 meters and cirrus level. They frequently indicate an approaching storm and can produce virga, which is rain or snow that does not reach the ground.
Low-level clouds, called stratus clouds, occur below 2,000 meters and often bring rain or snow.
Cumulonimbus or cumulus or 'thunderhead' clouds are the highest of all clouds and may reach above 15,000 meters. When cumulus clouds get big enough to produce thunderstorms, they are called cumulonimbus. Formed by the large amounts of rising hot air, their tops encounter high winds that cause them to spread out sideways, earning them the nickname 'anvil tops' (see the second picture). Just as it takes heat to evaporate water from the surface of the Earth... heat (energy) is released when water condenses to form clouds. In thunderheads, this energy can produce hail, damaging winds, lightning, torrential rain, and sometimes tornadoes. ☁️⛅🌤☁️🌦🌧🌩⛈🌪🌬☁️🌥🌤🌪🌩🌧⛈⛅⛅☁️☁️☁️🌥🌤 #clouds#whatareclouds#flyingonaplane#highinthesky#condensedair#typesofclouds#cirrusclouds#altocumulusclouds#stratusclouds#cumulonimbusclouds#scienceiseverywhere#scienceexplainseverything#scienceiscool#scienceteacher#science#sciencenerd#staynerdy

Fun in the ☀️
For most seniors, chronic pain such as osteoarthritis can be frustrating and debilitating. Better Nature wants to help as many people manage and control their pain with a natural #alternative. 💚🌿
Unlike other owls, snowy owls (Bubo scandiacus), like Harry Potter's Hedwig, are active during the day. ☀️ They actually start out with black feathers as chicks, which gradually turn white as they grow. ❄️ This one looks extremely unhappy with us. And who can blame it with all the changes we're causing in its native arctic habitat? 📷: Diego Delso/Wikimedia/CC BY-SA 4.0

WHEN KIDS DO THE MOST....😒 WAIT UNTIL THE END. LOL!!! What's up STEM Peps!⚛❄🔥 I visited a school yesterday and I had the opportunity to invite 4 scholars to perform the experiment using 4 different spoons, 2 of which look the same! All 4 of them 🌡changed colors once the kids inserted the spoons into cold ice water. They also did this with dry ice. What do you think the results showed with the dry ice? Which spoons changed colors the fastest? (The dry ice experiment isn't shown). Write your hypothesis and we will reveal the results tomorrow.
How does color changing items such as spoons, thermometers, mood rings, etc work? What's the science behind this phenomena? Thermochromic represents materials that signal temperature change by changing colors. When we have color changing spoons there is a temperature sensitive dye in them known as leucodyes. Leucodyes are organic chemicals that change color when energy makes their molecules shift back and forth. Based on if the temperature is hot or cold will determine how these molecules reflect light and thus present different colors. These spoons change colors once the temperature has decreased, such as inserting the spoons into ice. They immediately change colors. Once you warm the spoons up, they return to their original color. 👩🏽🏫Don't forget to respond to this question:
What do you think the results showed with the dry ice? Which spoons changed colors the fastest? (The spoons dipped in dry ice or the spoons dipped in ice?🤔). Write your hypothesis and we will reveal the results tomorrow.
It may be nostalgia that pushes people to reach for their vinyl, but who says you can't use some modern-day technology to make the experience a little more seamless? @Sony is mixing something old with a little something new through its PS-LX310BT Bluetooth-connected turntable that can broadcast the classic sound of vinyl through similarly equipped speakers and headphones. 🎶
Utah has some awesome stuff, like the #ClarkPlanetarium . A lot of great interactive science exhibits. It's a lot like a miniature #FranklinInstitute back home in Philly.
This is from a few weeks ago. I like this.
Zoology final exam. Parents were invited! Ayman and his partner were soooo lucky to dissect what turned out to be a momma shark 🦈 and found 6 baby sharks and 6 eggs inside her! This shark is ovoviviparous - eggs hatch inside her. First time his teacher ever saw such babies!! #scienceiscool#sharks#zoology#awesome
Have you ever wondered how scientists look at microscopic 3-dimensional tissue? One way of doing this is to embed the tissue in a special medium called OCT compound and freezing it on dry ice! Once the tissue is frozen in the mold, it can be sectioned in different planes and different thicknesses and visualized as is or with additional staining methods. #scienceiscool#talknerdytome#womendoingscience#developmentalbiology#iflscience

Mad Science is coming to VMCC on 1/26 to show kiddos (ages 3 1/2-6) with an adult how to make cool reactions from fun mixtures! $20/adult-child pair #chemistryisfun#scienceiscool#igh .
Who says you have to choose between science and art? Behold Alex's latest masterpiece: "Pluto's Moons." He was quite serious when he told me the name. "It's called beautiful moons, Alex?" "No Mom. Pluto's Moons!" #STEAM (science, technology, engineering, the ARTS, and math) #steamnotstem#scienceiscool#science#art#liberalarts
