Answer:
Seafloor spreading at the mid-ocean ridge provides the mechanism for tectonic plate movement. The Earth's mantle moves through convection, showing that tectonic plates are able to glide. The location of the plates was determined by locating their boundaries, using data on the Earth's magnetic field.

Africa is the only place where giraffes live in the wild
<h3><u>Answer;</u></h3>
It occurs over many generations.
It happens at the genetic level.
<h3><u>Explanation</u>;</h3>
- <em><u>Evolution is the process that involves change in the inherited traits of a population over generations. </u></em>
- <em><u>The traits involved are the expressions of genes that are copied and passed from the parents to the offspring during reproduction process. Mutations in these genes results to new traits and thus heritable differences among organisms.</u></em>
- <em><u>Therefore, evolution will only occur when there is change in gene frequency within a population over a given period of time. Genetic differences that are heritable are passed to the next generation.</u></em>
