Timthriall Carbóin

QuestionAnswer
Cén áit go bhfaightear an-chuid den charbón? Orgánaigh bheo
Céard a dhéanann an timthriall carbóin? athchúrsáil ar charbón
luaigh na dhá chineál charbóin aibitheach & bitheach
luaigh ceithre chéim sa timthriall carbóin Fótaisintéis, ábhair orgánacha, riospráid, dé-ocsaíd charbóin
Cad a dhéanann plandaí le linn fótaisintéise tógann plandaí CO2 isteach, á tiontú go glúcós.
Cad a dhéanann plandaí le linn riospráide scaoileann siad fuinneamh ó ghlúcós, agus scaoileann siad dé--ocsaíd charbóin leis.
cá dtarlaíonn fótaisintéis? clóraplas na cille planda
cén ceimiceán atá riachtanach don fhótaisnéis? clóraifill
cén ról atá ag fotaisnéis san atmaisféar? C02 a bhaint
Céard é an cothromóid fótaisintéise? Dé-Ocsaíd Charbóin + Uisce → Glúcós + Ocsaigin
céard é an chothromóid riospráide? Glúcós + Ocsaigin → Dé-Ocsaíd Charbóin + Uisce + Fuinneamh
céard is meath ann? ainm eile ar dhianscaoileadh
tabhair dhá shampla de dhianscaoilteoirí. fungais agus baictéir
céard is dianscaoilteoir ann? Orgánach a chothaíonn ar ábhar marbh, m.sh. fungais
céard is meath neamhiomlán ann? meath a tharlaíonn nuair atá easpa ocsaigine ann. Má tharlaíonn sé seo, ní tháirgtear dé-ocsaíd charbóin, ach breosla iontaise.
Má chuirtear ábhair mharbha faoi bhrú agus theocht ard, céard go dtiontófadh siad? Gás nádúrtha, amhola, móin, gual, breosla eile
Céard é cothromóid an dócháin CH4 + 2O2 → CO2 + 2H2O
Cén fáth gur fhadhb í an dóchán? Tá CO2 á cur san atmaisféar ag ráta níos tapúla ná mar atá á baint. Mar sin, tá an tiúchan CO2 ag méadú san atmaisféar.
Cén saghas gáis é dé-oscaíd charbóin? gás ceaptha teasa (coimeádann sé teas san atmaisféar)
Cad a tharlaíonn nuair a choimeádtar níos mó C02 san atmaisféar? Téamh domhanda
Cén chaoi go ndéanann breis C02 san atmaisféar dochair don atmaisféar? tuaslagann sé go haigéad agus cruthaítear aigéad carbónach, rud a dhéanann dochar d’éiceachórais uisceacha.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
