The two atmospheric layers that provide protection are the stratosphere and the mesosphere. The stratosphere contains the ozone layer, which absorbs and scatters harmful ultraviolet (UV) radiation from the sun. The mesosphere further protects Earth by burning up most meteoroids that enter the atmosphere, preventing them from reaching the surface. Together, these layers play crucial roles in shielding life on Earth from harmful solar and cosmic radiation.
The Earth's atmosphere consists of five main layers: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer plays a crucial role in supporting life; for instance, the troposphere contains the air we breathe and weather patterns, while the stratosphere houses the ozone layer that protects us from harmful UV radiation. The thermosphere is vital for communication, as it contains the ionosphere, which reflects radio waves. Understanding these layers helps us protect the environment and navigate climate change challenges.

The atmospheric pressure on the moon is essentially zero because the moon does not have a significant atmosphere. Unlike Earth, which has a dense atmosphere that exerts pressure due to the weight of the air above us, the moon lacks this gaseous envelope and thus has almost no atmospheric pressure.
Yes, remote sensing satellites operated by U.S. entities are regulated by the U.S. government through the National Oceanic and Atmospheric Administration (NOAA) and the National Reconnaissance Office (NRO). These regulations control the resolution and dissemination of images to protect national security and privacy concerns.
The atmosphere consists of 5 layers: the troposphere, which we live in; followed by stratosphere, mesosphere, thermosphere and exosphere. Air pressure at any of these layers is typically caused by hydrostatic pressure, defined as P = hpg, where P is the pressure, h is the height or depth of fluid, and g is the gravitational acceleration. In simple context, my physics lecturer once explained to me: the reason why we live under an atmospheric pressure of 1 bar is simply because there is a column of air above us. As we move upwards (e.g. in an airplane or on top of a mountain), the height of this column is reduced, thus the atmospheric pressure is less. Therefore, the first layer of atmosphere (or the lowest layer) will experience the highest air pressure.
Different layers of atmosphere protect us. They do it by blocking the unwanted radiations of the sun.
Ozone layer and mesosphere. They protects us from various obstacles.
Ozone layer protects us from UV rays. The outermost layer from meteors.
The various layers of atmosphere protect us. They protect us from the UV rays, Control the temperature etc.
The Earth is NOT an inert lump of rock flying round in space, but a very DYNAMIC system. The core of the Earth is hot liquid metal ( iron/nickel) mwhich rotates counter-clockwise to Earth's rotation. It also gives the Earth its magnetism *compass points). Outside the core the mantle, which convects, like water in a kettle, but much more slowly. This convection is driven by the heat of the core. The convecting mantle in turn moves the tectonic plates, mountains, earthquakes, volcanoes, ocean currents etc., The ocean currents form part of the hydro-sphere, which overlaps with the bio sphere ( all living matter). , which in turn is overlapped by the atmosphere. Then the stratosphere , and the ionosphere. From the hydro sphere outwards the Sun through gravity and radiation drives the whole system. The Sun through radiation gives us light and heat. The light radiation drives photosynthesis for plants to absorb CO2, and release oxygen. The are similar cycles for carbon and nitrogen. The Sun's gravitational attraction keeps Earth on its orbital track, otherwise we would 'fly-off' into outer space, and Earth would die, no sunlight. Also we rotate once a day to give us night and day . Our angle of rotation is angled at about 23 degrees and decreasing, this gives us our seasons. This axial angle of 23 degrees is currently decreasing to about 21 degrees and will then increas to about 28 degrees; it is called precession. It will affect climate change, and the polar ice caps , currently receding. Also our orbital track about the Sun is an ellipse which widens to nearly circular and then slims to a very narrow ellipse. This ellipse does not close up every year , but slightly overlaps. The Moon coupled with the Sun gives us our ocean tides. The mechanics of which are quite complicated, but understood. There is a lot more going on in/on Earth, that I have not mentioned. I leave you to try and find out for yourself. I hope from this, you understand that natural events, climate change included, on Earth are driven by many different forces, of which mankind has no control , but is only just beginning to understand. A lot of these events have been observed on other Solar System planets, the Martian ice caps changing size. The orbit of Mercury overlapping etc., The Earth is no different. If we lived on an inert lump of rock , no seasons, , no night and day, NOTHING!!!!!
Mesosphere does not protect us. It is because it does not contain an ozone layer.
The different layers of skin literally block bacteria like a forefield
Do not understand use of the word 'layer'
The Ozone layer in the upper Stratosphere.
Ozone exists in the stratosphere. It protects us from the UV rays of the sun.
Any of the atmospheric layers is good. Just don't want it where anything / anyone has to breathe it.
The atmospheric layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has distinct characteristics, such as temperature variations and composition, and plays a specific role in regulating Earth's climate and protecting life on the planet.
