Carbon Dioxide produces chemical weathering.
The extrusive igneous rock will float because that extrusive rock got cooled down fast then a regular extrusive. When the wind acted on it, it get cool down fast and the gases from the volcano gets trap in the rock and the weight of that rock is light. Also water and gases have different density so the gases in the rock will be pushed upward and the rock will float because of the weight and the gases in the rock. (P.s only a prediction)
Animals can break down rock material through physical weathering, such as digging, scratching, or burrowing. Plants can break down rock material through root growth, where roots penetrate cracks and crevices in rocks, causing them to break apart over time. Both processes contribute to the breakdown of rocks into smaller particles through mechanical means.
It falls and break
The rock doesnot breakdown from gas, but only water would be able to break it down.
Weathering or erosion.
It when water goes into the rock and then the water freezes and break the rock
Yes, lichens can produce acids to break down rock.
Plants which make substances that break down rock are called lichens. Lichens are known to release acids that break down rocks.
Sediments.
YES

Erosion
The animales that break down rock are moles and earth worms and any other animale that can dig
all the mechanical and chemical that breaks down rock
fossil
Yes
