Redwood Forest: -3 abiotic and 3 biotic factors of the redwood forest -What types of plants grow there and how they survive -The type of soil and how it affects the plants

Abiotic factors weather, temperature, chemical components whereas Biotic factors animals, plants and bacteria.

Explanation:

Abiotic factors of redwood forest include weather, temperature, chemical components whereas animals, plants and bacteria are the biotic factors present in the redwood forest. Sword fern, redwood sorrel, rhododendron, huckleberry, salal, azalea, and other shrubs are the types of plants that grow in the redwood forest. The soil type is sandy or weathered limestone derived soils which enhances the growth of redwood plants.

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.
