Mine reclamation involves reopening a mine that was previously thought to be void of useful minerals. true false

False

Mining is a process that involves the displacement of large amount of soil and rocks from a region in order to excavate valuable minerals and resources. It results in environmental degradation as it disturbs the natural habitat of living species, contaminate natural resources like air and water. Mine reclamation is a process of restoring the land where, mining took place. This is done by completely filling up the mining site with piles of soil, afforestation(planting trees), using land for agriculture purpose to minimize the environmental impacts such as erosion of soil, loss of native biodiversity and others.

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 .. .

the answer is c) an oak tree
