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.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
