A magnetosphere is the region around an astronomical object in which phenomena are dominated or organized by its magnetic field. Earth is surrounded by a magnetosphere, as are the magnetized planets Mercury, Jupiter, Saturn, Uranus and Neptune. Jupiter's moon Ganymede is magnetized, but too weakly to trap solar wind plasma. Mars has patchy surface magnetization. The term "magnetosphere" has also been used to describe regions dominated by the magnetic fields of celestial objects, e.g. pulsar magnetospheres. The magnetosphere of Earth is a region in space whose shape is determined by the extent of Earth's internal magnetic field, the solar wind plasma, and the interplanetary magnetic field (IMF). In the magnetosphere, a mix of free ions and electrons from both the solar wind and the Earth's ionosphere is confined by magnetic and electric forces that are much stronger than gravity and collisions. In spite of its name, the magnetosphere is distinctly non-spherical. On the side facing the Sun, the distance to its boundary, which varies with solar wind intensity, is about 70,000 kilometers, 10 to 12 Earth radii or RE, where 1 RE = 6371 kilometers; unless otherwise noted, all distances here are from the Earth's center. The boundary of the magnetosphere ("magnetopause") is roughly bullet shaped, about 15 RE abreast of Earth and on the night side (in the "magnetotail" or "geotail") approaching a cylinder with a radius 20 to 25 RE. The tail region stretches well past 200 RE, and the way it ends is not well-known. The outer neutral gas envelope of Earth, or geocorona, consists mostly of the lightest atoms, hydrogen and helium, and continues beyond 4 to 5 RE, with diminishing density.

thermosphere
the ionosphere is located in the thermosphere under the exosphere and above the mesosphere

What is the reason you categorize the atmosphere into different layers?
Density of air decreases on increasing height, hence we categorize the atmosphere into different layers from Troposhere to Ionosphere at particular kilometers respectively.
What are earths first 3 layers in the atmosphere?
Troposphere, Mesosphere, Stratosphere, and Thermosphere. Thermosphere has two levels in itself; exosphere, and ionosphere
What layer of the atmosphere reflects radio waves?
the ionosphere.
Describe the 2 layers of the thermosphere?
The "ionosphere" is a layer that contains charged particals, or ions. It includes the thermosphere and part of the mesophere. The "thermosphere" is the outermost layer of earths atmosphere. The "mesophere" is the atmospheric layer located between the stratosphere and the thermosphere.
The Earths atmosphere is composed of how many different layers?
The Earth's atmosphere is composed in FIVE different layers. The first one is the Troposphere, which is the closest to the Earth's surface. The second one is the stratosphere. The third atmosphere is called the mesosphere, which contains the coldest air temperature. The forth is thermosphere, which contains the ionosphere that are made up of electrically charged particles (note that the ionosphere is not one of the atmosphere). The last part of the atmosphere is the exosphere, which is the region of the space travel. It is also the furthest atmospheric layer from the Earth.
The layers of the atmosphere that contains the ionosphere is the?
thermosphere
What and where are the ionosphere and exosphere?
The layer of the atmosphere that contains the ionosphere and exosphere is called the thermosphere. The exosphere is at the top and the ionosphere is at the bottom.
What are the four minor layers of the atmosphere?
Ozonosphere, Ionosphere, Exosphere, and Magnetosphere.
What are the four minor layers of the earth's atmosphere?
the magnetosphere,exospher,ionosphere,and the ozonosphere.
What layers mostly make up the atmosphere?
The layers of the Earth atmosphere are: * Troposphere - peplosphere * Stratosphere * Mesosphere * Thermosphere - ionosphere * exosphere * magnetosphere

What are the diff layers of the atmosphere?
Troposphere, Stratosphere, Mesosphere, Thermosphere, Ionosphere, Exosphere
What opart of the layers contains ions?
Ionosphere contains ions. It is a part of atmosphere.
What layer of the atmosphere contains the ionosphere?
Thermosphere These charged particles comprise the layers of the ionosphere that coexist with the uncharged, or "neutral," atoms and molecules of the thermosphere.
What are all the layers of the earth and the atmosphere in order from the core to space?
The layers of the Earth are the inner core, the outer core, the mantle, the crust, and the atmosphere. The layers of the atmosphere are the troposphere, stratosphere, mesosphere, ionosphere, and exosphere.
Which 2 minor layers are actually part of a major layer?
Troposphere and stratosphere are the minor layers of Earth's atmosphere. The troposphere is where weather occurs, and it is the closest to the Earth. The stratosphere is the second closest and where planes fly. It is 40 kilometers thick, and the troposphere is 12 kilometers thick.
Is the ionosphere is one of the layers of the atmosphere?
Yes, it is part of the Thermosphere, the last part of the atmosphere before the Exosphere, 'outer space'.& its after the Mesosphere, it also is stuck with poor old Ionosphere.
