The core has the largest density, being made of iron and nickel
The mantle has an intermediate density and the crust has the lowest density.
A fog is just a cloud at the ground. Fog formation can occur in two ways. First, the air is cooled to the dew point which leads to the formation of fog droplets. When the air temperature is the same as the dew point temperature, condensation occurs on tiny particles floating in the air. The second method of fog formation requires water to evaporate from the surface into the air, raising the dew point until condensation occurs.
This is false because not all of earths system can store carbon
