<span>Risks of emphysema, asthma and cancer are associated with the tars and hydrocarbons in inhaled smoke. The tar acts to coat the bronchial sacs, in effect causing the bronchial sacs to be damaged beyond repair and suffocating the smoker over time. The hydrocarbons contain cancer causing chemicals that enter the blood stream and are carried throughout the body.</span>
The answers would be:
Igneous Rocks - They are made from hot magma.
Sedimentary Rocks - They are made from weathered pieces of rock.
Metamorphic Rocks - They are rocks, small or large which reformed due to high temperature.
If you'd like to know more, read on:
Igneous rocks are formed when hot magma is cooled and then it hardens into a rock. The word igneous comes from the word, "ignis" which means "of fire. They can be formed beneath the Earth or on the surface.
Sedimentary rocks are formed from weathered pieces of rock. These pieces are called <u>sediments</u>. They can also be made out of other material. When these sediments settle, it continues to do so until so much sediment accumulate and they start to press down on each other. The sediments then start to go through compaction and sedimentation which for a sedimentary rock.
Metamorphic rocks form under heat and pressure. They are squeezed and shaped and go through <u>metamorphosis </u>or go through change. A metamorphic rock can be formed from any other type of rock as long as it goes through changes due to intense pressure and/or heat.
