Where does the Aurora Borealis occur in the atmosphere?
Aurora borealis occur in the Earth’s ionosphere, and result from collisions between energetic electrons (sometimes also protons, and even heavier charged particles) and atoms and molecules in the upper atmosphere.
Which layer of the atmosphere contains electrically charged particles that create the Aurora Borealis northern lights )? Group of answer choices?
A dense layer of molecules and electrically charged particles, called the ionosphere, hangs in the Earth’s upper atmosphere starting at about 35 miles (60 kilometers) above the planet’s surface and stretching out beyond 620 miles (1,000 km).
In which layer do the Aurora’s occur?
In the ionosphere, the ions of the solar wind collide with atoms of oxygen and nitrogen from the Earth’s atmosphere. The energy released during these collisions causes a colorful glowing halo around the poles—an aurora. Most auroras happen about 97-1,000 kilometers (60-620 miles) above the Earth’s surface.
What aurora borealis causes?
Auroras occur when charged particles (electrons and protons) collide with gases in Earth’s upper atmosphere. Those collisions produce tiny flashes that fill the sky with colourful light. That is why auroras occur almost every night in the northern sky, from August to May.
What atmospheric layer causes northern lights?
When that wind slams into Earth’s ionosphere, or upper atmosphere, the aurora is born. In the Northern Hemisphere, the phenomenon is called the northern lights (aurora borealis), while in the Southern Hemisphere, it’s called the southern lights (aurora australis).
In which layer of the atmosphere do rainstorms occur *?
the Troposphere
Explanation: Almost all weather occurs in the lowest layer of the atmosphere, called the Troposphere. The exception being large storms like hurricanes and large Thunderstorms. These storms have clouds with great vertical development and the tops of these storms go into the Stratosphere.
Which layer of atmosphere is responsible for aurora formation?
the thermosphere
The aurora (Northern Lights and Southern Lights) mostly occur in the thermosphere. The thermosphere is a layer of Earth’s atmosphere. The thermosphere is directly above the mesosphere and below the exosphere.
Where does the aurora borealis occur in the ionosphere?
The spectacular Aurora borealis occurs in the Earth’s ionosphere. The ionosphere is the layer of the Earth that is ionized by cosmic and solar radiation. It lies 46 to 621 miles above the Earth’s surface.
Earth’s ionosphere overlaps the top of the atmosphere and the very beginning of space. The Sun cooks gases there until they lose an electron or two, which creates a sea of electrically charged particles. 2. The ionosphere is where Earth’s atmosphere meets space
What makes the ionosphere glow in the Sun?
The ionosphere constantly glows Airglow is what we call the bright swaths of light that shine from Earth’s upper atmosphere. It happens when atoms and molecules in the upper atmosphere, excited by sunlight, emit light to shed their excess energy.
Why does the ionosphere change from day to night?
Because it’s formed when particles are ionized by the Sun’s energy, the ionosphere changes from Earth’s day side to night side. When night falls, the ionosphere thins out as previously ionized particles relax and recombine back into neutral particles.
