What are aurora lights caused by?
When the electrons reach Earth’s thin upper atmosphere, they collide with nitrogen and oxygen molecules, sending them into an excited state. The excited electrons eventually calm down and release light, which is what we see as the aurora.
How are auroras formed quizlet?
Auroras are caused by the interactions of the particles ejected from the Sun and the earth’s magnetosphere. These interactions cause the particles to glow in beautiful greens, blues, reds, purples… constant stream of particles flowing from the Sun is known as the solar wind.
What causes the aurora borealis or northern lights quizlet?
A glow in the Earth’s ionosphere caused by the interaction between the Earth’s magnetic field and charged particles from the Sun (The Solar Wind). It gives rise to the “Northern Lights”, or Aurora Borealis, in the Northern Hemisphere, and the Aurora Australis in the Southern Hemisphere.
What causes the aurora borealis simple explanation?
When the solar wind gets past the magnetic field and travels towards the Earth, it runs into the atmosphere. As the protons and electrons from the solar wind hit the particles in the Earth’s atmosphere, they release energy – and this is what causes the northern lights.
Where do the auroras occur quizlet?
Mesosphere: The mesosphere is the third layer of the Earth’s atmosphere. Meteors or rock fragments burn up in the mesosphere. Thermosphere: The thermosphere is the fourth layer of the Earth’s atmosphere. The Auroras occur here.
What are auroras quizlet?
Terms in this set (24) Auroras. Light shows caused by collisions between charge particles from the sun and earth atmospheric gases, such as oxygen and hydrogen.
What causes the aurora borealis or Northern Lights to occur 1 point?
Bottom line: When charged particles from the sun strike atoms in Earth’s atmosphere, they cause electrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights.
What is the primary cause of the auroras northern and southern lights quizlet?
How is Aurora Borealis made?
What causes auroras northern and southern lights )? Quizlet?
Auroras, (Aurora Borealis “Northern Lights” and Aurora Australis “Southern Lights”) are produced here. A colorful, glowing display in the sky of the Southern Hemisphere caused when particles from the sun strike oxygen and nitrogen atoms in the ionosphere; also called the Southern Lights.
What does the greenhouse effect cause quizlet?
The greenhouse gases in the atmosphere absorb some of this infrared radiation and re-reflect it back towards the earth. This causes the green house effect and results in an increase in average mean temperatures on earth. passes through the atmosphere from the sun to the earth’s surface.
What makes Aurora Borealis happen?
the aurora borealis is caused by particles from the sun blowing toward the earth with the solar wind. When these particles hit the earth’s magnetic field, the crash of atoms and molecules creates a beautiful sight. Oxygen atoms reflect green and red light.
What makes Aurora happen?
An aurora happens when energetic electrically charged particles, like electrons, collide with atoms of gas as they accelerate along the Earth’s magnetic field lines in the upper atmosphere. Those collisions cause the atoms to give off light.
Do the northern lights exist on other planets?
Aside from Mars, all of the other planets which also experience an aurora (both Northern Lights and Southern Lights) are those with active magnetic fields. And, because they have magnetic fields, their Auroras, like Earth, are majorly active on their poles.
How is Aurora formed?
Aurora are formed from the solar wind interacting with the Earth’s magnetosphere and atmosphere.
