Which layer of the atmosphere is electrically charged?
the ionosphere
What is the ionosphere? The ionosphere is a very active part of the atmosphere, and it grows and shrinks depending on the energy it absorbs from the Sun. The name ionosphere comes from the fact that gases in these layers are excited by solar radiation to form ions, which have an electrical charge.
What atmospheric layer contains the ionosphere?
thermosphere
Ionosphere. The ionosphere is not a distinct layer like the others mentioned above. Instead, the ionosphere is a series of regions in parts of the mesosphere and thermosphere where high-energy radiation from the Sun has knocked electrons loose from their parent atoms and molecules.
What layer of the atmosphere is the magnetic field?
magnetosphere
Contained within the Earth’s thermosphere, the magnetosphere is the region where the Earth’s magnetic field interacts with the charged particles coming from the Sun in the solar wind.
Which layer of the atmosphere contains the ionosphere?
mesosphere
The ionosphere (/aɪˈɒnəˌsfɪər/) is the ionized part of Earth’s upper atmosphere, from about 48 km (30 mi) to 965 km (600 mi) altitude, a region that includes the thermosphere and parts of the mesosphere and exosphere.
Which layer of atmosphere is used for radio communication?
Ionosphere
Answer: Ionosphere of the atmosphere helps in radio transmission.
What layer of the atmosphere contains the ionosphere?
The ionosphere (/aɪˈɒnəˌsfɪər/) is the ionized part of Earth’s upper atmosphere, from about 48 km (30 mi) to 965 km (600 mi) altitude, a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar radiation.
Which layer has electrically charged particles called ions?
ionosphere
ionosphere and magnetosphere, regions of Earth’s atmosphere in which the number of electrically charged particles—ions and electrons—are large enough to affect the propagation of radio waves.
Where does the heat come from in the stratosphere?
The direct heat source for the stratosphere is the Sun. Air in the stratosphere is stable because warmer, less dense air sits over cooler, denser air. As a result, there is little mixing of air within the layer. The ozone layer is found within the stratosphere between 15 to 30 km (9 to 19 miles) altitude.
How is the temperature gradient in each layer of the atmosphere determined?
The temperature gradient in each layer is determined by the heat source of the layer. Most of the important processes of the atmosphere take place in the lowest two layers: the troposphere and the stratosphere.
What happens to gas molecules in the atmosphere?
When gas molecules are warm, they move vigorously and take up more space. Air density and air pressure are lower. Warmer, lighter air is more buoyant than the cooler air above it, so it rises. The cooler air then sinks down, because it is denser than the air beneath it. This is convection, which was described in the Plate Tectonics chapter.
Why is the mesosphere the coldest part of the atmosphere?
Mesosphere. Temperatures in the mesosphere decrease with altitude. Because there are few gas molecules in the mesosphere to absorb the Sun’s radiation, the heat source is the stratosphere below. The mesosphere is extremely cold, especially at its top, about −90 degrees C (−130 degrees F).
