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.
What else can I help you with?
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 the charged layers in the thermosphere called?
The charged layers in the thermosphere are called the ionosphere. This region of the Earth's atmosphere is characterized by high concentrations of ions and free electrons, which are produced by the interaction of solar radiation with the gas molecules. The ionosphere plays a crucial role in radio wave propagation and aurora formation.
What are earths first 3 layers in the atmosphere?
The Earth's first three layers of the atmosphere, starting from the surface, are the troposphere, stratosphere, and mesosphere. The troposphere is where most weather occurs, the stratosphere contains the ozone layer that protects us from the sun's harmful rays, and the mesosphere is where meteors burn up upon entering the atmosphere.
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.
Is most of the ozone in the earths atmosphere located in the ionosphere?
No, most of the ozone in Earth's atmosphere is located in the stratosphere, which is the second layer of the atmosphere. The ionosphere is located much higher in the atmosphere and is composed of ionized gases, not ozone.
The layers of the atmosphere that contains the ionosphere is the?
thermosphere
What are the four minor layers of the earth's atmosphere?
The four minor layers of the Earth's atmosphere are the tropopause, stratopause, mesopause, and exosphere. These layers mark the boundaries between the main layers of the atmosphere and have distinct characteristics based on temperature, composition, and altitude.
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 are the 4 minor layers of the atmosphere?
The four minor layers of the atmosphere below the thermosphere are the troposphere, stratosphere, mesosphere, and the ionosphere. These layers vary in thickness and composition, with each playing a unique role in Earth's atmospheric systems.
Which of the layers of the atmosphere allows for the reflection of a radio waves back to the earth surface?
The "ionosphere".
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.
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 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.
What is composition of ionosphere?
The ionosphere is composed of several layers of the Earth's atmosphere that contain ionized particles, mainly electrons and positive ions. These layers are responsible for reflecting radio signals, which enables long-distance communication. The ionosphere plays a crucial role in the propagation of radio waves and the formation of auroras.
What are the names of the six layers of the atmosphere shown?
The six layers of the atmosphere, from lowest to highest, are the troposphere, stratosphere, mesosphere, thermosphere, exosphere, and ionosphere. Each layer has distinct characteristics and plays a different role in Earth's atmosphere.
