Answer:
Carbon makes up the majority of a tree's bulk. The carbon originates from the photosynthesis of carbon dioxide. Plants transform the sun's energy into chemical energy, which is trapped inside the bonds of carbon molecules formed from atmospheric carbon dioxide and water during photosynthesis. Yes, carbon dioxide from the air we breathe ends up in "food" molecules (called glucose), each of which includes six carbon atoms (and 12 hydrogen atoms and 6 oxygen atoms). There is, however, a downside to this. Plants utilise the energy contained in part of the carbon molecules they create to keep themselves alive and proliferate.Explanation:
Answer:
Examples of mechanical weathering include frost and salt wedging, unloading and exfoliation, water and wind abrasion, impacts and collisions, and biological actions. All of these processes break rocks into smaller pieces without changing the physical composition of the rock.
Explanation:
Mechanical weathering involves mechanical processes that break up a rock: for example, ice freezing and expanding in cracks in the rock; tree roots growing in similar cracks; expansion and contraction of rock in areas with high daytime and low nighttime temperatures; cracking of rocks in forest fires, and so forth.
Mass number = protons + neutrons
If you have the # of protons and the mass #, subtract the number of protons from the mass number to get the number of neutrons.
If you have the number of neutrons and the mass number, subtract the number of neutrons from the mass number to get the number of protons.
