Answer:
Energy comes to the earth surface in the form of sunlight. When the sunlight strikes the earth surface, some energy is absorbed by the earth through vegetation in the process of photosynthesis, while more are reflected back into the space but these light radiation trapped by greenhouse gases such as carbondioxide, methane and nitrous oxide etc which increases the temperature and causes global warming which changes our climate.
Answer:
In quiet breathing inspiration involves muscular contractions and expiration is passive.
Explanation:
Respiration process involves two different stages, inspiration - inhalation- and expiration - exhalation-.
During inspiration, the diaphragm <u>contracts</u> and goes down, while intercostal muscles also <u>contract</u> and go up. These actions enhance the size of the thoracic box and <u>reduce internal pressure</u>. As a result, air flows in and fills the lungs.
During expiration, the <u>diaphragm relaxes</u> and the volume of the thoracic box diminishes, which causes the <u>pressure inside to increase</u>. In consequence, the lungs contract and the air is expulsed outside.
