õhkkondadele

õhkkondadele is a term related to atmospheric layers. The Earth's atmosphere is divided into several distinct layers, each with its own unique characteristics. These layers are primarily defined by temperature variations. The lowest layer, the troposphere, extends from the Earth's surface up to about 7 to 15 kilometers. This is where weather occurs and most of the atmospheric mass is concentrated. Above the troposphere lies the stratosphere, which extends to about 50 kilometers. The ozone layer, crucial for absorbing ultraviolet radiation from the sun, is located within the stratosphere.

Further up is the mesosphere, reaching approximately 85 kilometers. This is the coldest layer of the atmosphere, and meteors typically burn up here. Above the mesosphere is the thermosphere, extending to about 600 kilometers. Temperatures in the thermosphere can be very high due to absorption of solar radiation, but it is so thin that it would not feel hot. Within the thermosphere, the ionosphere, a region containing electrically charged particles, plays a role in radio wave propagation. The outermost layer is the exosphere, which gradually fades into outer space. The term "õhkkondadele" likely refers to these different atmospheric layers or the concepts associated with them.
