Explain what would happen to the atmosphere in the absence of sunlight. give two supporting details for your answer and use complete sentences. can someone me with this .

In the absence of sunlight the plants which are dependent on sunlight for making food that is photosynthesis would die.

Also the people will suffer as sunlight is a good source of Vitamin D and in absence of sunlight they will not get it so easily.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

hope this .. .
