2.how i petroleum formed ?
3. what are igneous rock?

Answer 1

Answer:

1.The bobbing observed in laboratory experiments of pumice floatation is explained by trapped gas expanding during the heat of day, which causes the stones to temporarily float until the temperature drops.

2.petroleum is formed when large quantities organisms primarily zooplankton and algae underneath sedimentary rock are subjected to intense heat and pressure

3.Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.
