What is the hottest layer in the Sun’s atmosphere photosphere corona core radiative zone chromosphere?
The relatively thin layer of the solar atmosphere located above the sun's surface. The temperature in the chromosphere rises from 6000° K to about 20 000° K making it hotter than the photosphere but not as hot as the higher atmosphere the corona. The sun's dynamic atmosphere is called the corona.
What is the hottest surface of the Sun?
The temperature rises from the surface of the Sun inward towards the very hot center of the Sun where it reaches about 27,000,000 Fahrenheit (15,000,000 Celsius).
Is the corona the hottest layer of the Sun?
On the Sun however, the reverse occurs: its outermost layer, the corona, is nearly 500 times hotter than the underlying layer, the photosphere. To explain this cosmic conundrum, astronomers have long theorized that some unknown mechanism must be vigorously heating the corona.
Is the corona hotter than the photosphere?
Edlén and Grotrian's finding that the sun's corona is so much hotter than the photosphere – despite being further from the sun's core, its ultimate source of energy – has led to much head scratching in the scientific community.
How hot is the Sun’s atmosphere?
These are impulsive heating bursts that individually reach incredibly hot temperatures of some 10 million Kelvins or 18 million degrees Fahrenheit – even greater than the average temperature of the corona – and provide heat to the atmosphere.
Where is the hottest place in the solar system?
The hottest place in the Solar System is the Sun, obviously. And the hottest part of the Sun is its core. The surface of the Sun is a mere 5,800 Kelvin, while the center of the Sun is around 15 million Kelvin. That's hot.
What is the hottest layer?
Scientists believe that the inner core is the hottest layer of the Earth, that it is composed mostly of iron and nickel, and that although it is hot enough to be a liquid, it acts as a solid because of the immense amount of pressure on it.
What is Earth’s hottest layer?
core Earth's core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth's surface, and has a radius of about 3,485 kilometers (2,165 miles).
What is hotter than the Sun?
And the answer: lightning. According to NASA, lightning is four times hotter than the surface of the sun. The air around a stroke of lightning can peak at 50,000 degrees Fahrenheit, while the surface of the sun is around 11,000 degrees. Meanwhile, magma can reach temperatures near 2,100 degrees.
How hot is each layer of the Sun?
The centre of the Sun: about 15 million kelvin (K). Radiative Zone: Temperature falls from about 7 million to about 2 million K across this zone. Convection Zone: drops from 2 million K to 5800K in this zone. Photosphere: about 5800K, although sunspots are about 3800 K – that's why they are dark.
Why is the corona the hottest part of the Sun?
Because the coronal material is so thin and tenuous, only a tiny portion of all the sound energy in the photosphere needs to bleed up into the corona and be absorbed in order to heat it to the observed temperatures.
What is the hottest part of the Earth?
Death Valley holds the record for the highest air temperature on the planet: On 10 July 1913, temperatures at the aptly named Furnace Creek area in the California desert reached a blistering 56.7°C (134.1°F). Average summer temperatures, meanwhile, often rise above 45°C (113°F).
What is the hottest part of the Universe?
The dead star at the center of the Red Spider Nebula has a surface temperature of 250,000 degrees F, which is 25 times the temperature of the Sun's surface. This white dwarf may, indeed, be the hottest object in the universe.
Why is thermosphere the hottest layer?
Because there are relatively few molecules and atoms in the thermosphere, even absorbing small amounts of solar energy can significantly increase the air temperature, making the thermosphere the hottest layer in the atmosphere. Above 124 mi (200 km), the temperature becomes independent of altitude.
Why is the core the hottest layer?
The interior of Earth is very hot (the temperature of the core reaches more than 5,000 degrees Celsius) for two main reasons: The heat from when the planet formed, The heat from the decay of radioactive elements.
Which is hotter sun or lava?
Lava is indeed very hot, reaching temperatures of 2,200° F or more. But even lava can't hold a candle to the sun! At its surface (called the "photosphere"), the sun's temperature is a whopping 10,000° F! That's about five times hotter than the hottest lava on Earth.
What’s hotter than lava?
Magma is hotter than lava, depending on how recently the lava reached the surface and if the magma and lava are from the same magma chamber below the…
What is the hottest layer of the earth?
core Earth's core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth's surface, and has a radius of about 3,485 kilometers (2,165 miles).
Which is the hottest layer?
Scientists believe that the inner core is the hottest layer of the Earth, that it is composed mostly of iron and nickel, and that although it is hot enough to be a liquid, it acts as a solid because of the immense amount of pressure on it.
What is the second hottest layer of the Earth?
The Outer Core-The Outer Core is made up of mainly iron, which becomes extremely hot, reaching over 4000 degrees Celsius. The outer core can get so hot to the point that the iron melts into a molten form. The Mantle-The Mantle is the second layer from the surface of the earth.
Is lava hotter than the Sun?
Lava is indeed very hot, reaching temperatures of 2,200° F or more. But even lava can't hold a candle to the sun! At its surface (called the "photosphere"), the sun's temperature is a whopping 10,000° F! That's about five times hotter than the hottest lava on Earth.

Is there anything hotter than Sun?
The highest temperature ever reached under controlled conditions is an astonishing two billion degrees. It was created in the so-called Z-machine at the Sandia Laboratories, New Mexico, which uses incredibly high electric currents and magnetic fields to release radiation from atoms.
Is fire hotter than Sun?
No. The surface of the sun is approximately 10,000 degrees Fahrenheit while a wood burning fire is about 600 degrees Fahrenheit.
Can magma melt diamond?
To put it simply, a diamond cannot melt in lava, because the melting point of a diamond is around 4500 °C (at a pressure of 100 kilobars) and lava can only be as hot as about 1200 °C.
Is Blue fire hotter than lava?
Actual lava is red-orange in color, given its temperature. Truly-blue lava would require temperatures of at least 6,000 °C (10,830 °F), which is much higher than any lava can naturally achieve on the surface of the Earth.
Is the mantle the hottest layer?
The mantle is a liquid like layer that is 2,900 km thick. The outer core is made of nickel and metal. The inner core is the hottest layer, above 9000 Fahrenheit and it is 1250 km thick!
What is the second hottest layer of the atmosphere?
Thermosphere Thermosphere | Encyclopedia.com.
Is mesosphere hottest layer?
The temperature in the mesosphere grows colder with the altitude. This is because there are few gas molecules in the mesosphere to absorb the Sun's radiation. The only heat source is the stratosphere below. The mesosphere is extremely cold, especially at the top, dropping to a temperature as low as -90°C.
Would a diamond melt in lava?
To put it simply, a diamond cannot melt in lava, because the melting point of a diamond is around 4500 °C (at a pressure of 100 kilobars) and lava can only be as hot as about 1200 °C.
