The rock a) destroys and create rock b) changes and recyclers earth’s rocks c) happens once every million years d) changes all rocks into igneous rock

B) Changes and recyclers Earth's rocks

In earth, there a 3 kinds of rocks available namely volcanic, sedimentary, and igneous. These diverse rock types can be changed into each other.

Sedimentary rock can wind up molten, transformative or another sedimentary rock, igneous rock can end up volcanic, sedimentary or another changeable rock and molten rock can end up sedimentary, transformative or another volcanic rock. This type of interconversion is explained by rock cycle.  

This conversion occurs through natural phenomenon such as erosion, melting, weathering, effect of heat and pressure, etc.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
