If by "sky", what you mean "atmosphere", the answer is relatively straightforward.
Let's look at the possible heat sources for the earth and atmosphere.
In the case of the earth, heat comes from two places: pressure and solar radiation. The mass of the earth causes a non-trivial compression of the inner parts - that is, gravity keeps the earth tightly compressed into a ball. Basic physics tells us that raising the pressure without reducing the volume on something will significantly increase the internal temperature of that thing. As the Earth is made of materials that generally will not compress, the gravitational forces keeping the Earth together also result in a very significant heating of the internal portions of the Earth.
As a secondary source, the Earth is heated by absorbed Solar Radiation. Earth, as a solid, absorbs radiation (in all forms) quite easily. Most of that absorbed radiation is converted into heat (that is, it raises the temperature of the earth). A portion (perhaps a majority) of that heat is then radiated back out into the atmosphere. However, the total amount of energy being absorbed by the Earth at any instant is much, much smaller than the heat caused by internal compression (i.e. absorbed solar radiation may raise the local earth temperature by up to 100 degrees F, but internal pressure can generate 3-5,000 degrees)
As for the atmosphere, it too has two major sources of heat: directly absorbed solar radiation, and "waste" heat radiated back from the Earth.
Compared to the solid Earth, the gaseous nature of the atmosphere does a very poor job of absorbing most solar radiation. In addition, much of the radiation that is absorb is not converted into heat - rather, it chemically alters the nature of the atmosphere (the Ozone layer is a prime example of the chemical alteration of the atmosphere by solar radiation). So, direct solar radiation only heats the atmosphere by a very tiny bit.
However, the Earth itself provides a significant source of heat, both from re-radiating solar radiation that the Earth has absorbed (mostly in the form of infra-red radiation, which doeseasily warm gases), and by directly heating gas by exposure to hot Earth (think of gases being expelled by volcanoes).
As an analogy, think of the Earth as an electric stove burner, and the atmosphere as the pot you put on it. The burner is very hot, driven by internal heating process (electric in the case of the burner, gravitational pressure in the case of the Earth). The pot on top only gets hot by "stealing" (absorbing) heat from the burner - it can't generate heat all by itself. Thus, while the Earth is mostly self-warming, the atmosphere can generally only heat itself by absorbing waste heat from the Earth.
What else can I help you with?
Why are the gases in the troposphere layer denser than the gases in the other layers?
The gases in the troposphere are denser than those in higher atmospheric layers because the troposphere is the lowest layer of the atmosphere, where air pressure is greatest due to the weight of the air above it. As altitude increases, the gravitational pull on air molecules decreases, leading to lower pressure and less density in the upper layers. Additionally, the troposphere contains a higher concentration of water vapor and other gases, contributing to its overall density compared to the stratosphere and beyond.
Which part of the apple would represent the thickness of the lower layer of the atmosphere?
The edible part, because the "lower layer of the atmosphere" would be the troposphere that takes 75% of the mass of air in the atmosphere itself. The core is the earth, and the skin is the rest of the atmosphere.
What layers of the atmosphere contains ozone layers?
The stratospheric region contains ozone layer. It protects us from UV rays.
What layer is the ozone a part of?
You can find ozone in any layer of the atmosphere, but in the lower layers it does not last long. The so-called ozone layer is in the lower portion of the stratosphere, at a height where it takes a long time to dissociate.
Which sphere is the ozone layer located in?
stratosphereOzone is found in some amount in all layers of the ATMOsphere. It is at its highest concentration in the lower stratosphere.
What is lower layer of atmosphere?
The atmosphere as we know it, has got 4 layers. Troposphere is the lowest.
What layer of the atmosphere is Boeing?
Boeing aircraft can fly in the troposphere and lower stratosphere layers of Earth's atmosphere.
What layer of the atmosphere do Boeing 747s fly in?
The Boeing 747 can fly in the troposphere and lower stratosphere layers of Earth's atmosphere.
What are the lower layers of the earth's atmosphere?
The lower layers of Earth's atmosphere are the troposphere and the stratosphere. The troposphere is where weather events occur and is the layer closest to Earth's surface. The stratosphere lies above the troposphere and contains the ozone layer, which helps protect Earth from the sun's harmful UV radiation.
Why carbon dioxide gas is not present in lower layer of atmosphere?
it is present in all layers. What gave you the idea it wasn't?
Why are the gases in the troposphere layer denser than the gases in the other layers?
The gases in the troposphere are denser than those in higher atmospheric layers because the troposphere is the lowest layer of the atmosphere, where air pressure is greatest due to the weight of the air above it.

Additionally, the troposphere contains a higher concentration of water vapor and other gases, contributing to its overall density compared to the stratosphere and beyond.
How does the density of Earth's crust compare to the other layers?
The density of Earth's crust is generally lower than the denser mantle and core layers. The crust is composed mainly of less dense rocks such as granite and basalt, while the interior layers consist of denser materials like iron and nickel. This density variation is a key factor in shaping Earth's structure and influencing geological processes.
Why does not Co2 form the lower layer in the atmosphere?
CO2 is a well-mixed gas in the Earth's atmosphere, meaning it is distributed fairly evenly throughout the various layers. However, other gases such as nitrogen and oxygen make up the majority of the atmosphere and are heavier than CO2, preventing CO2 from forming a distinct lower layer. Gravity helps keep all gases relatively well-mixed in the atmosphere.
What layer of the earth is at 40000 feet altitude?
When you're above the surface you are dealing with layers of the atmosphere, not layers of the Earth. At 40,000 feet you will be either in the upper troposphere or the lower stratosphere depending or you latitude.
What are the layers of the atmosphere made of?
The layers of the atmosphere are composed mainly of different gases. The lower layer, the troposphere, contains primarily nitrogen and oxygen. The stratosphere is higher up and contains an ozone layer. Beyond that, in the mesosphere and thermosphere, the composition is more variable with gases like oxygen, nitrogen, and helium.
How many layers are in the coral reef?
it has 3 layers the somet (the upper layer) the photic(the middle layer)and the twlight(the lower layer)
What layers of the atmosphere have weather?
The troposphere is the layer of the atmosphere that contains weather phenomena such as clouds, precipitation, and storms. Weather events mainly occur in the lower part of the troposphere, closest to Earth's surface.
