Does radius of Earth increase in summer due to thermal expansion?

Answer 1

Which summer, the north or the south?

...but seriously, the internal temperature distribution of the Earth, starting just a foot or so into the ground, is constant. So no, no thermal expansion.

Answer 2

The Sun moves counter clock wise relative to the Galaxy. as it moves The earth moves along with it. As a result the Earth increases in mass and its orbital radius as well.

In the sumertime the earth is at the apehelium,which is at the point where its the futherst away from the sun.In the Sumertime the Earth receives more insolation area but less radiation intensity than the winter in the Northern hemisphere. In ether case the Earth does absorb more mass radiation than it loses in Space.The result is slight increase of temperature which is very minimal and the increase in volume due to temperature is extremely small .
However with time the Earth'smass can increase significantly along with an increase in its radius vector.That is the reason why terrestial days get longer every year as time goes by.

The same scenario can also apply to some particular stars and Galaxies.That could be also why Galaxies appear to expand in the Universe.

Answer 3

No, not at all. When it's summer here, it is winter in the opposite hemisphere. And besides, the ground temperature, when you go down about 10 or 20 feet, is the same all year around. With an Earth radius of 3,950 miles, that 20 feet is a very very small fraction.

Answer 4

I dont think so, because when it is summer it is winter in the other half of the world. They cancel out.

Answer 5

yes no thermal expansion.

Answer 6

Not sure...but since its only summer in one hemisphere and winter in the other...would that be a couterbalance.

Answer 7
