Plants can break large rocks into tiny pieces. How is it possible for plants to be able to mechanically weather rocks by breaking them into smaller pieces? The roots of the plant grow into the cracks of the rock forcing the rock to break.
O The plant absorbs all the water from the soil leaving the rocks dry and brittle.
O The plant wraps itself around the rock and forces it to crumble.
The acidity of the plant forms new types of smaller rocks.

The roots of the plant grow into the cracks of the rock forcing the rock to break.

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.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
