Rainwater.
No, not all rocks can be melted. Rocks with high melting points, such as granite, can require very high temperatures to melt. Additionally, some rocks can react chemically or decompose before reaching their melting point.
Some atoms do not chemically react in nature because they are already stable.
Some rocks are more reactive than others due to differences in their mineral composition. Rocks that contain minerals that are chemically unstable or have a greater tendency to react with other substances will be more reactive. Additionally, the presence of certain elements or ions in the rock can also make it more prone to chemical reactions.
rocks and water
No, all organisms react to their environment to survive.
Yes is some factors but matters which kind of factors
No. Rainwater is usually slightly acidic because of the carbon dioxide dissolved in it. Sometimes, it can be strongly acidic, if pollutants like sulphur dioxide and nitrogen dioxide are dissolved in it. Both weakly and strongly acidic rainwater react with some rocks, but only ones that are alkaline. Chalk is almost pure calcium carbonate and reacts fairly quickly with rainwater. Other rocks that contain calcium carbonate include limestone and marble and these react a little more slowly. But some rocks, like sandstone, are actually acidic and don't react with rainwater (though they are still physically weathered by rain). Granite also doesn't react with rainwater and it physically weathers much more slowly.
Helium is considered an inert noble gas. Only some unstable compunds of helium are known today: HeNe, HgHe10, WHe2.
Every rocks have formed in special environment some form by lava and some form in sea, raver and lakes so the rock which is formed inside water so they have fossils of specific environment and the rocks form by lava it was hot so there were no possibility to preserved living organism.
they have fossils and pieces of the environment from the past inside of them
Soil, sand, gravel, rocks, water, air, light
Flurocarbons react with ozone and deplete it. It causes various adverse effects.
