What causes surface ocean currents to be deflected?

The Coriolis effect causes surface ocean to be deflected.

Explanation:

The Coriolis effect causes ocean currents to be deflected.

Choriolis effect (named after its discoverer Gaspard Coriolis), is the tendency that any body in motion on the Earth's surface has to change its course due to the rotational direction and the speed of the Earth.

In the northern hemisphere, the attraction is clockwise (to the right) and in the southern hemisphere, the attraction is in the reverse (counterclockwise).

This effect also affects sea currents as the water (liquid) undergoes deformations.

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.
