Necessary because it keeps heat in and keeps the planet at the right temperature for life.
It can harm the planet if more pollution occurs and the greenhouse gas effect traps too much heat and causes global warming
The Drilling sample of the Seafloor spreading theory helped in determining rock ages on the floor of ocean.
Explanation:
The formation of crusts of ocean by the process of volcanic eruptions in the ridges of the middle ocean is the theory of seafloor spreading proposed by Hammond Hess. The movement of tectonic plates continuously forms sea floors through spreading of seafloor. The several evidences in support of this theory has been seen, of which some are – molten material eruptions, magnetic stripes in rocks and rock ages.
The drilling evidence is the final one that was proved by taking samples of rock by drilling in ocean and by bringing them with pipes. The observation of these rocks proved that older rocks were collected from farther ridges and youngers are found in the central ridges.
Answer:
Please Provide more information, but generally you can use any measuring tools. If its volume, the formula is V = W * H * L
Explanation:
Answer: The taproot
Explanation: A deep taproot helps plants use moisture held in deeper soil layers, and they can have great drought resistance compared to fibrous-rooted plants. An example is honey mesquite (Prosopis juliflora), which is known to send its roots down 150 feet to get water.
Answer: It helps to regulate circadian rhythm
Exposure to natural light during the day helps regulate the circadian
rhythm, which improves sleep pattern. The term circadian rhythm refers to our
biochemical, physiological and behavioral processes in approximately 1 full day
cycle. Circadian rhythm plays an
important role in
controlling when we fall asleep and when we wake up.
During day light, the secretion of melatonin or sleep hormone is
suppress by melanopsin that keeps people awake and alert. Nevertheless, during nighttime,
melanopsin stimulates the release of melatonin to signal sleeping time. Therefore,
this hormone works the entire day and has direct effect on the circadian
rhythm, which acts as a regulator of our biological clock.
