UV rays can cause skin cancer and damage plants, including phytoplankton, the base of the oceans food chain. Coldest layer of Earths atmosphere is the MESOSPHERE.

All life on this planet is affected by the changes that happen in this layer, as all the weather changes take place in the troposphere. What's in the Atmosphere It's the level of the atmosphere where we live and breathe. The mesosphere is the coldest layer because it has essentially nothing to heat it. "It gets very cold up there, we'll get down to minus -80C (-112F)," he says. She is very sharp in it absorbs radiation from the sun. But opting out of some of these cookies may affect your browsing experience. Hottest layer of Earths atmosphere is the thermosphere. Air composition and atmospheric pressure is not consistent throughout the atmosphere, however, and varies at different altitudes, giving the atmosphere 5 distinct principle layers. WebThe top of the mesosphere, called the mesopause, is the coldest part of Earth's atmosphere. WebThe troposphere is hotter near the Earth's surface because heat from the Earth warms this air.

"And then when we manoeuvre the balloon up and down, we use an electrically powered compressor that can pull like up to 800W. Some sources distinguish between the terms "near space" and "upper atmosphere", so that only the layers closest to the Krmn line are described as "near space". The top of the mesosphere is the coldest area of the Earth's atmosphere because temperature may locally decrease to as low as 100 K (-173C).

A Chinese balloon which floated over the US this month caused a diplomatic incident, though China denied it was spying (Credit: Reuters), Russ Van Der Werff of US high-altitude balloon makers Aerostar has a better idea than most. ", Aerostar has launched more than 3,000 high-altitude balloons in recent years (Credit: Aerostar), Keeping those electrical instruments running more than 20km above the Earth's surface isn't easy, either.
