WitrynaThe troposphere is the lowest layer of our atmosphere. Starting at ground level, it extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. We humans live in the troposphere, and nearly all weather occurs in this lowest layer. Witryna13 lut 2024 · The least dense layer is the exosphere which is the outermost layer of the atmosphere. In my science book it says, "it is least dense because it is farthest from …

Of these layers of the atmosphere, which is the least dense? A.

The most common molecules within Earth's exosphere are those of the lightest atmospheric gases. Hydrogen is present throughout the exosphere, with some helium, carbon dioxide, and atomic oxygen near its base. Because it can be hard to define the boundary between the exosphere and outer space (see "Upper boundary of Earth" at the end of this section), the exosphere may be considered a part of the interplanetary medium or outer space.

Witryna18 mar 2024 · The Earth’s atmosphere has five main layers and a sixth layer, the ionosphere, that overlaps the mesosphere, thermosphere, and exosphere. Troposphere: The Densest Layer in the Atmosophere. The bottom layer, which is the layer closest to the Earth, is the most dense of the five layers. This layer is known as the troposphere. WitrynaSynopsis. The thermosphere is the atmospheric region from ∼85 to ∼500 km altitude, containing the ionosphere. It is characterized by high temperature and large variability, in response to changes in solar ultraviolet radiation and solar-driven geomagnetic activity. The composition of the lower thermosphere is primarily N2 and O 2, similar ...
