What is it called when particles from the sun strike atoms in the ionosphere near the poles?
The described activity causes the generation of the Aurora Borealis and the Aurora Australis.
What is the part of the atmosphere called that energy from the sun strikes gas molecules and causes them to glow?
The part of the atmosphere is called the ionosphere. When energy from the sun strikes gas molecules in this layer, it causes them to become ionized and emit light, creating phenomena like the auroras.
Where and why do auroras occur in earth's atmosphere?
Where: It occurs in the Thermosphere.Why: In the thermosphere, temperature increases steadily as altitude increases because nitrogen and oxygen atoms absorb solar radiation, and so in the ionosphere (the lower region of thermosphere at the altitude of 80 - 400 km) solar radiation that is absorbed by atmospheric gases causes the atoms of gas molecules to lose electrons and to produce ions and free electrons. Interaction between solar radiation and the ionosphere causes the phenomena known as auroras.
Which part of the thermosphere causes the Aurora Borealis?
The Aurora Borealis and its southern counterpart the Aurora Australis are formed high in the atmosphere in the ionosphere, which is sometimes considered as part of the thermosphere, the outermost actual atmosphere. Above this layer, the exosphere has so few molecules that they can escape into space.(see the related question below)
In which layer of the atmosphere do the Auroras occur?
In the upper mesosphere and the lower thermosphere, gas particles become electrically charged. Because these charged particles are called ions, this part of the thermosphere is called the ionosphere. In polar regions these ions radiate energy as shimmering lights called auroras, usually in latitudes above 50 degrees. The Aurora Borealis and its southern counterpart the Aurora Australis are formed high in the atmosphere in the ionosphere, which is sometimes considered as part of the thermosphere, the outermost actual atmosphere. Above this layer, the exosphere has so few molecules that they can escape into space. For more information visit the question "What causes the Aurora Borealis?"
What is it called when particles from the sun strike atoms in the ionosphere near the poles?
The described activity causes the generation of the Aurora Borealis and the Aurora Australis.
In which layer of the atmosphere are the ionized particles that causes the aurora borealis?
Thermosphere, to be specific Ionosphere.
How can solar flares disrupt radio and satellite communications and power grids?
Charged particles from the sun can disrupt the Earth's magnetic field. This causes electromagnetic induction, producing abnormal currents in power grids, possibly destroying electronic equipment. Radio communications rely on the ionosphere which reflects radiowaves. Particles can enter the ionosphere and disrupt these radio communications.
What layer are cool particles pulled down by gravity?
Cool particles are typically pulled down by gravity at the troposphere layer. The troposphere is the lowest layer of the Earth's atmosphere where weather phenomena occur, and gravity causes particles to settle towards the Earth's surface within this layer.
What is the name given to the movement of the particles which causes the mixing?
The movement of particles that causes mixing is called diffusion. It is the process by which particles move from an area of high concentration to an area of low concentration, resulting in a more uniform distribution of the particles.
What is the energy that causes charged particles to move is called?
The energy that causes charged particles to move is called electrical energy. This energy is a result of the movement of electrons in a conductor due to a voltage or potential difference applied across the material.
What is it called when the particles of an object start to move faster and causes it to grow?
Thermal expansion
What is the part of the atmosphere called that energy from the sun strikes gas molecules and causes them to glow?
The part of the atmosphere is called the ionosphere. When energy from the sun strikes gas molecules in this layer, it causes them to become ionized and emit light, creating phenomena like the auroras.
What process causes nitrogen to be released as a gas?
Atmosphere causes 78% nitrogen to be released as a gas
What is the type of energy that causes particles to move?
The type of energy that causes particles to move is called kinetic energy. This energy is associated with the motion of particles, and it increases as the speed of the particles increases. When thermal energy is added to a substance, it can increase the kinetic energy of its particles, causing them to vibrate or move more rapidly.
What is a substance that causes pollution called?
A substance that causes pollution is called a pollutant. Pollutants can be in the form of chemicals, gases, or particles that are harmful to the environment and human health.
What causes borealis?
An Aurora Australis or an Aurora Borealis occurs when streams of particles from the sun's solar winds hit the earth's atmosphere at an angle (as can only happen at the poles). These particles interact with the edges of the earth's magnetic field and when they collide with the gases in the ionosphere, the particles glow creating curtains of blue, green and magenta. An aurora is sometimes accompanied by a crackling sound.
