Question 1

Define plate tectonics

Answer 1

Plate tectonics is the movement of the earth’s crust into different sections clued tectonic plates.

Question 2

How do plate tectonics impact species diversity?

Answer 2

Plate tectonics has led to the formation of physical barriers, land bridges, and changes in climate zones which have caused species isolation, adaptation and evolution.

Question 3

Provide an example of plate tectonics impacting species diversity

Answer 3

Llamas and camels are both distant cousins and have fulfilled similar ecological roles. Kangaroos and cattle have similar roles in Australia, with kangaroos being marsupial mammals and cattle being placental mammals.

Question 4

How do mountains impact species diversity?

Answer 4

Mountains form physical barriers which isolate gene pools.

Question 5

Consequences of plate tectonics on speciation

Answer 5

Plate tectonics cause consequences such as the separation of gene pools, the formation of physical barriers, and changes in climate zones. All of which contribute to speciation.
