there can be carbon dioxide
Gases, mainly.
Is madE of rock
yes
there can be carbon dioxide
Yes.
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)
The most critical characteristic for a sedimentary rock to serve as a potential reservoir rock for oil or gas is its porosity. This refers to the amount of open space within the rock that can hold fluids. Without sufficient porosity, the rock cannot store significant amounts of oil or gas.
When rock melts into magma, it releases volatile gases trapped within the rock. These gases can include water vapor, carbon dioxide, and sulfur dioxide. The release of gases contributes to volcanic eruptions and helps drive the movement of magma within the Earth's crust.
gases
peameable rock means that it can be permenated or penetrated, especially by liquids or gases
No. it's made up of ice, rock and frozen gases!
It is a rocky planet.
