Oenopides was the first to discover and measure the tilt.
He came up with about 24 degrees around 480BCe using geometry and measurements of sun angles at several times of year.
Hope this helps
Answer:
N₂
Explanation:
The primary greenhouse gases in the atmosphere are carbon dioxide, methane, nitrous oxide, water vapour and ozone. These gases allow sunlight to reach the Earth's surface unhindered. The sunlight heats the surface. The heat as infrared reradiated to the atmosphere, the greenhouse gases absorb the heat energy. They do not allow heat to escape back trapping' the gases in the lower atmosphere.
Nitrogen is an inert gas present in the atmosphere is about 78%.
Only some nitrogen-fixing bacteria such as Rhizobium which fixes atmospheric nitrogen into the soil.
Thus, N₂ (nitrogen) is not a greenhouse gas.
Fix the foundation if that does not wrk find a material too help stabilize the soil hope this helps
