The thermosphere is heated by solar radiation particularly in the far ultraviolet range; much of this is filtered out by the atmosphere's lower layers - but in the these upper regions it is more exposed to this kind of radiation.
The outermost layer of the sun's atmosphere is called the corona. It is visible during a solar eclipse as a halo of light surrounding the sun. The corona is much hotter than the layers below it, reaching temperatures of millions of degrees Celsius.
The planet Mars has a core that is primarily made out of iron. It is surrounded by a silicate mantle and a much thicker crust than earth. Mars Global Surveyor noticed sedimentary rocks which indicates the presence of water.
The thermosphere is the hottest layer of the Earth's atmosphere because it absorbs high-energy solar radiation, particularly ultraviolet and X-ray radiation. Despite the high temperatures, the air molecules in the thermosphere are so spread out that they cannot transfer their heat effectively, leading to the perception of extreme heat without much actual warmth.
The thermosphere can reach temperatures as high as 2,500 degrees Celsius (4,532 degrees Fahrenheit) due to the absorption of high-energy solar radiation. However, despite these high temperatures, the thermosphere would not feel hot to us because the air density is so low that it cannot transfer much heat to objects passing through it.

A peach is not a good model for Earth's layers because its skin represents Earth's crust, but Earth's layers are much thicker and have different compositions than a peach. The peach model oversimplifies the complexity of Earth's layers and does not accurately represent the mantle, outer core, and inner core beneath the crust.
Because the particles in the thermosphere are very spaced out. A normal thermometer would even measure it below zero, but it has a very high temperature.
Yes, much thicker.
Thicker than now
yes much thicker than humans thir bones are thicker too
yes, the dermis is much thicker than the epidermis
The meteors will travel through the exosphere and thermosphere without much trouble due to the lack of air in those layers, but when they hit the middle layer, there are enough gases to cause friction and create heat to burn up in the Mesosphere.
Venus' atmosphere is much thicker than Earth's
It is affected most directly by the suns radiation
The mantle is thicker than the crust. The Earth's crust is relatively thin, with an average thickness of about 5-70 km, while the mantle is much thicker, extending from the base of the crust to a depth of about 2,900 km.
