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.
What else can I help you with?
How is an Aurora borealis different from an Aurora austral is?
The Aurora Borealis, also known as the Northern Lights, occurs in the Northern Hemisphere, while the Aurora Australis, or Southern Lights, takes place in the Southern Hemisphere. Both phenomena are caused by charged particles from the sun interacting with the Earth's magnetic field and atmosphere, resulting in beautiful light displays. The specific colors and shapes of the auroras can vary based on atmospheric conditions, but their fundamental nature is the same, differing only by location.
How are droughts caused by humans and nature?
nature because humans dont control when it rains
Are wildfires weather related geologic in nature or caused by humans?
Caused by humans and weather related
Is a tsunami caused by the wheather nature or by humans?
Tsunamis are caused by earthquakes.
How do you categorize a tornado as weather related geologic in nature and or caused by humans?
A tornado is categorized as weather related geologic in nature because it is a natural weather phenomenon caused by atmospheric conditions. Tornadoes are not caused by humans, so they do not fall under the category of being human-induced.
What is the difference between moral evil and natural evil?
moral evil is evil caused by humans Natural evil is caused by nature.
How have the Aurora Borealis changed over the years?
The Aurora Borealis, or Northern Lights, has remained a natural phenomenon driven by solar activity and Earth's magnetic field. However, variations in intensity and frequency have been observed, often correlating with the solar cycle, which lasts about 11 years. Climate change and increasing levels of light pollution may also impact visibility and the experience of the auroras in certain regions. Overall, the fundamental nature of the auroras has not changed, but their visibility and the conditions under which they are observed may vary over time.
Why does the Aurora Borealis happen and what causes this stunning natural phenomenon in the sky?
The Aurora Borealis, also known as the Northern Lights, occurs when charged particles from the sun collide with gases in Earth's atmosphere. These collisions create colorful light displays in the sky, typically near the North and South Poles. The colors are produced by different gases in the atmosphere, such as oxygen and nitrogen, emitting light as they interact with the solar particles. This stunning natural phenomenon is a result of the Earth's magnetic field interacting with solar winds, creating a beautiful light show in the night sky.
Were is plutonium found?
An insignificant amount of plutonium exists in nature. Mostly, plutonium is obtained from nuclear reactions caused by humans.
What happens if you whistle at the northern lights?
Whistling at the northern lights is a cultural belief in some places, like Scandinavia, where it's thought to make them dance or come closer. Scientifically, the northern lights (aurora borealis) are caused by particles from the sun interacting with the Earth's magnetic field, so whistling would not impact them physically. It's more about enjoying the experience and feeling connected to nature.
Why is the Aurora Borealis only visible in the northern hemisphere?
The Aurora Borealis, also known as the Northern Lights, is only visible in the northern hemisphere because it is caused by solar particles interacting with the Earth's magnetic field near the North Pole. This phenomenon creates colorful light displays in the sky that can be seen in countries like Canada, Norway, and Iceland.
Why does the aurora borealis occur and what causes this stunning natural phenomenon in the night sky?
The aurora borealis occurs when charged particles from the sun collide with gases in Earth's atmosphere, creating colorful light displays. This natural phenomenon is caused by the Earth's magnetic field interacting with solar winds, resulting in the stunning light show in the night sky.
