earth bigger or the same size

[dusty1]

Is this planet getting bigger, the reason I ask is because every time you see time team, the further they dig down the earlier they go in time, if not who comes along and covers it up?

Some bits get bigger- some get smaller-
Erosion takes soil, rock etc from exposed places- the wind may take some away but a lot is transported away by rivers and dumped elsewhere.
Also think about the number of leaves and other plant life that has rotted down over the years and built up on the ground surface. I laid down a path of square slabs down my garden some 20 years ago in the form of stepping stones. The surface of those slabs is in places an inch or more below the surface of the surrounding ground now.

Thanks burnhal I had not thought of that.

Yes, it is getting bigger. The universe is expanding, so the earth is expanding to keep pace with it.

Cosmic dust settles on the earth - so is getting bigger all the time.
