The sun generates energy in its core in
a process called nuclear fusion
. During nuclear fusion, the sun’s extremely high pressure and hot temperature cause hydrogen atoms to come apart and their nuclei (the central cores of the atoms) to fuse or combine. Four hydrogen nuclei fuse to become one helium atom.
Does the sun take in and use energy?
The sun generates energy from a process called
nuclear fusion
. … During the fusion process, radiant energy is released. It can take 150,000 years for energy in the sun’s core to make its way to the solar surface, and then just a little over eight minutes to travel the 93 million miles to Earth.
How does the sun absorb energy?
Once the sun’s energy reaches earth, it is intercepted first by the atmosphere. A small part of the sun’s energy is directly absorbed, particularly by certain gases such as
ozone and water vapor
. Some of the sun’s energy is reflected back to space by clouds and the earth’s surface.
Does the Sun make noise?
The surface of the Sun produces sound waves
because the surface is convecting and this produces pressure waves that travel into the inner corona. But yes, the surface does produce sound waves, but they have very low wavelengths measures in hundreds of miles! …
What is the main source of energy on Earth?
The energy of the sun
is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells. The sun heats the earth’s surface and the Earth heats the air above it, causing wind.
What is the loudest thing in the universe?
The Krakatoa volcanic eruption
: Not only did it cause serious damage to the island, the eruption of Krakatoa in 1883 created the loudest sound ever reported at 180 dB.
What was the loudest recorded sound on Earth?
The loudest sound in recorded history came from
the volcanic eruption on the Indonesian island Krakatoa at 10.02 a.m. on August 27, 1883
. The explosion caused two thirds of the island to collapse and formed tsunami waves as high as 46 m (151 ft) rocking ships as far away as South Africa.
Can you hear the sun from Earth?
Today, we can hear the Sun’s movement — all of its waves, loops and eruptions — with
our own ears
. This sound helps scientists study what can’t be observed with the naked eye.
What are the 3 major sources of energy for the Earth?
Primary energy sources take many forms, including nuclear energy, fossil energy — like oil, coal and natural gas — and renewable sources like
wind, solar, geothermal and hydropower
.
What is the best source of energy?
- Bananas. Bananas may be one of the best foods for energy. …
- Fatty fish. Fatty fish like salmon and tuna are good sources of protein, fatty acids, and B vitamins, making them great foods to include in your diet. …
- Brown rice. …
- Sweet potatoes. …
- Coffee. …
- Eggs. …
- Apples. …
- Water.
What are the 2 main sources of energy on earth?
At the most foundational level, however, there are just two sources of energy. Two sources provide more than 99 percent of the power for our civilization:
solar and nuclear
. Every other significant energy source is a form of one of these two. Most are forms of solar.
What is the loudest animal in the Universe?
The loudest animal in the world is
the blue whale
: its vocalisations of up to 188 decibels can be heard 160km away.
What is the loudest sound made by a human?
The loudest sound ever created by humans, not by natural causes, was said to be
the atomic bomb blasts over Nagasaki and Hiroshima
. Those clocked in at around 250 decibels. NASA’s highest recorded decibel reading was 204 and that was the first stage of the Saturn V rocket.
Can you talk in space?
When astronauts are out in space,
they can whistle, talk
, or even yell inside their own spacesuit, but the other astronauts would not hear the noise. In fact, the middle of space is very quiet. … That’s why the astronauts use radios to communicate—even if they’re floating in space right next to each other!
What Hz is harmful?
Especially dangerous is infrasound
Why is 194 dB the loudest sound possible?
A sound of 194 dB has a pressure deviation of 101.325 kPa, which is ambient pressure at sea level, at 0 degrees Celsius (32 Fahrenheit). Essentially, at 194 dB,
the waves are creating a complete vacuum between themselves
.
