Answer:
The main mechanism that is behind the configuration of the present landscape and the formation of oceans is the plate tectonic movement, which is continuously taking place since the last 250 million years. This plate movement is going on due to the generation of large uprising current in the mantle, which is commonly known as the convection current. These currents are originated due to the heat radiated from the extreme interior of the earth.
Due to this motion of plates, there formed three different types tectonic boundaries such as the convergent, transform and divergent boundary. The high elevated mountains are formed adjacent to the convergent plate boundaries and the divergent plate boundaries are responsible for the formation of ocean bodies.
The continents are generally comprised of continental crust, which is comprised less denser minerals and rocks, and on the other hand, the oceans are comprised of oceanic crust which are made up of heavier minerals and rocks. It is because of this reason, the continents floats and it rises up during the collision of any two plates namely continent-continent, continent-ocean or oceanic-oceanic plate collision.

A. human-environment interaction
Explanation:
This kind of study which involves impact of human activities on the environment falls under the human-environment interaction theme of geography.
It entails how human activities continues to shape his immediate environment.
- Geographic theme of location is associated with where on earth something can be found. It could be absolute or relative location.
- Geographic theme of place involves the physical and human setting of a place.
- Geographic theme of region defines a particular area which are classified under some certain categories.
The fitting answer to this problem is the theme of human - environment interaction.
Ocean waves depend on wind for energy. The wind blows on the surface of the water, the energy is transferred from the wind to the waves through vibration of particles. Energy transfers from potential energy to kinetic energy
