I HAVE 20 MINS!!
A science teacher shows his students an image of a volcanic mountain range and informs them it was created by the movement of Earth’s tectonic plates. He asks his students to explain how this occurred. Which student’s explanation is best?

Student A

An oceanic plate converged with an oceanic plate. Both plates subducted, forcing lava upward towards the surface of the Earth causing a volcanic eruption which created the mountains.

Student B

A continental plate converged with a continental plate. Neither plate subducted so lava was forced upward towards the surface of the Earth causing a volcanic eruption which created the mountains.

Student C

An oceanic plate converged with a continental plate. The more dense, continental plate sank below the less dense oceanic plate causing magma to rise up through a weak spot in Earth’s crust to create volcanic mountains.

Student D

An oceanic plate converged with a continental plate. The more dense, oceanic plate sank below the less dense continental plate causing magma to rise up through a weak spot in Earth’s crust to create volcanic mountains.

Acetic acid  /əˈsiːtɪk/, systematically named  ethanoic acid  /ˌɛθəˈnoʊɪk/, is a colourless liquid  organic compound  with the  chemical formula  ch3cooh (also written as ch3co2h or c2h4o2). when undiluted, it is sometimes called  glacial acetic acid.  vinegar  is no less than 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. acetic acid has a distinctive sour taste and pungent smell. in addition to household vinegar, it is mainly produced as a precursor to  polyvinyl acetate  and  cellulose acetate. it is classified as a  weak acid  since it only partially  dissociates  in solution, but concentrated acetic acid is corrosive and can attack the skin.acetic acidnamespreferred iupac nameacetic acidsystematic iupac nameethanoic acidother namesvinegar (when dilute); hydrogen acetate; methanecarboxylic acid[1][2]identifierscas number64-19-7  3d model (jsmol)interactive image3dmetb00009 reference506007chebichebi: 15366  chemblchembl539  chemspider171  drugbankdb03166  echa infocard100.000.528ec number200-580-7e numbere260  (preservatives)gmelin reference1380iuphar/bps1058keggd00010  meshacetic+acidpubchem  cid176rtecs numberaf1225000uniiq40q9n063p  un number2789inchiinchi=1s/c2h4o2/c1-2(3)4/h1h3,(h,3,4)  key:   qtbsbxvteameqo-uhfffaoysa-n  smilescc(o)=o

A. they hold atoms  together with a molecule.its a force that exist between molecules. hope this .
