Where is the thickest layer of skin?

Skin is thickest on the palms and soles of the feet (1.5 mm thick), while the thinnest skin is found on the eyelids and in the postauricular region (0.05 mm thick).

What is the coldest layer?

mesosphereThe top of the mesosphere is the coldest area of the Earth’s atmosphere because temperature may locally decrease to as low as 100 K (-173°C).

What is the thickness of Earth?

The layers of Earth are: Crust – 5 to 70 km thick. Mantle – 2,900 km thick. Outer Core – 2,200 km thick.

Why is exosphere so hot?

The particles in the exosphere are moving very quickly, so the temperature there is quite hot. … Since the “air” is so thin in the exosphere – it is almost a vacuum – there are very, very few particles. We feel warmth when particles hit our skin and transfer heat energy to us.

What is the thinnest and coldest layer of the earth?

Earth’s LayersEarth Layers:CRUST- The crust is the thinnest layer.- made of rock.- hard and rigid.- coldest layer.- outermost layer – it’s the land that we stand on everyday.

What part of the sun is hottest?

coreThe 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.

What is the thinnest layer of the earth answers com?

crustThe crust is the thinnest layer of the Earth at 5-30 km thick.

Where is the Earth’s crust the thinnest?

As the diagram below shows, Earth’s crust is thinnest under the oceans and thickest under continental mountain ranges. The crust is home to all life on Earth. Earth’s crust and the very top of the mantle together form the (LIHTH-uh-SFEER).

In which layer do we live?

troposphereWe humans live in the troposphere, and nearly all weather occurs in this lowest layer. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere.

What keeps the Earth’s core hot?

There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements.

What layer is the thickest?

mantleThe Earth can be divided into four main layers: the solid crust on the outside, the mantle, the outer core and the inner core. Out of them, the mantle is the thickest layer, while the crust is the thinnest layer.

Which is the hottest layer?

thermosphereThe thermosphere is often considered the “hot layer” because it contains the warmest temperatures in the atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km.

What are the 7 layers of earth?

They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust. Except for the crust, no one has ever explored these layers in person.

What layer of the sun is hottest?

CoreThe hottest part of the Sun is the core, at 28,080,000°F, on average.
