Answer:

Plate tectonic have effected our atmosphere, hydrosphere and biosphere on following ways-

Atmosphere- Plate motion have brought two different plates closer to one another and separated from one another, when this plates come together this can lead to the formation of various Volcanoes which have effected the atmosphere. Gases mainly the greenhouse gases which were being added in the atmosphere have increased the earth temperature. Mountain ranges that were formed in the geological past would have also effected the weather patterns by means of precipitation through the rain shadow effect, which ultimately effect the climate over time. Movement of the land masses in the different latitudes would have also effected the climate of that area in the geological past.

Hydrosphere- Due to the plate motion opening and closing of water bodies have occurred in the geological past. Hot spot and volcanic activity can lead to development of new land masses along with the the change in the positions of land and oceans would have effected in the global oceanic circulation along with the heat distribution.

Biosphere- Due to the movement of the plates it would have effect the then biosphere as due to the fact the plates have moved away from each other their would have been little movement of the organism what this can lead to an new way of evolution.
