Question

Energy form various sources is considered to have been derived from the sun. Do you agree? Justify your answer.

Answer 1

Answer:

yes ..

Explanation:

since sun is the ultimate source of energy .we can say that all type of energy have been derived from sun..

Answer 2

$\huge{\boxed{\bf{\red{Answer:-}}}}$

$\sf \: Yes, \: sun \: is \: the \: ultimate \: source \: of \: energy. \: directly \: or \\ \sf \: indirectly, \: all \: the \: forms \: of \: energy \: derived \: from \: solar \\ \sf \: energy.$

$\sf1. \: \bf{Non - renewable \: source \: of \: energy} \: - \: Fossil \: fuels \\ \sf \: \: \: \: \: like \: coal, \: petroleum \: and \: natural \: gas \: are \: formed \: due \\ \sf \: \: \: \: \: to \: burial \: of \: large \: plants \: and \: ancient \: creaturs.$

$\sf2. \: \bf{Renewable \: sources \: of \: energy }\: - \: They \: are \: indirectly \\ \sf \: \: \: \: \: derived \: from \: solar \: energy \: such \: as :$

$\sf \: (a) \: \bf {Energy \: from \: flowing \: water} - \sf \: Clouds \: are \: formed \\ \sf \: \: \: \: \: \: \: when \: water \: in \: lakes, \: rivers, \: seas, \: etc., \: evaporates \\ \: \: \: \sf \: \: \: \: due \: to \: solar \: energy. \: They \: bring \: rainfall \: and \: snow \\ \sf \: \: \: \: \: \: \: fall.$

$\sf(b) \: \bf{Wind \: energy} - \: \sf \: Wind \: arises \: due \: to \: uneven \\ \ \: \: \: \: \sf \: heating \: of \: the \: earth's \: surface \: by \: the \: sun \: rays \: at \\ \sf \: \: \: \: \: \: two \: different \: adjoining \: places. \: Wind \: possesses \\ \: \: \: \: \: \: \: \sf kinetic \: energy.$

$\sf(c) \: \bf{Bio - energy} - \: \sf \: Plants \: in \: the \: process \: of \: photosynthesis \\ \sf \: \: \: \: \: convert \: the \: solar \: energy \: into \: food \: (chemical \: energy). \\ \: \: \: \: \: \sf This \: food \: is \: consumed \: by \: animals.$

$\sf(d) \: \bf{Wave \: energy} - \: \sf \: The \: waves \: are \: generated \: by \\ \: \: \: \: \: \: \sf strong \: winds \: (due \: to \: solar \: energy) \: blowing \\ \: \: \: \: \: \: \sf across \: the \: sea.$

$\sf(e) \: \bf{Ocean \: thermal \: energy} - \sf \: Sun \: is \: responsible \: for \\ \sf \: \: \: \: \: \: the \: temprature \: difference \: between \: the \: water \: at \\ \sf \: \: \: \: \: \: the \: surface \: and \: water \: at \: depth \: in \: seas \: and \\ \sf \: \: \: \: \: \: oceans.$

$\sf3. \: \bf{Solar \: heating \: devices} - \sf \: They \: derive \: their \: energy \\ \: \: \: \sf \: directly \: from \: solar \: energy \: and \: conert \: it \: into \: other \\ \sf \: \: \: \: \: usable \: forms \: of \: energy.$
