Answer:
(A) When two oceanic plate moves in the opposite direction, it leads to the formation of new crust and the boundary along which this new crust is formed is known as the Mid-Oceanic ridge. For example Mid-Atlantic ridge.
(B) When an oceanic plate crashes with a continental plate, then the oceanic plate being heavier sinks below the continental plate, producing a subduction zone is created, which is commonly known as the Benioff zone. It is marked by deep trenches and deep-focus earthquakes are generated.
(C) When two continental plates share a divergent plate boundary, if slowly undergoes rifting and with the increasing time, the plates get separated from one another forming a rift valley. For example, the East African rift valley system.
(D) Strike-Slip fault zone is the boundary along which two continental plates slide past one another. Shallow-focus earthquakes are generated in this region. For example, The San Andreas fault.
(E) When two continental plates converges then it forms the sandwich pattern, where high mountain ranges occur. The area undergoes extreme thrusting and folding. for example, The Himalaya.
Answer:
this is because the polar regions have less sun rays sticking them compared to any other regions hence the temperature at the polar region is always low
Explanation:
Gravity plays a very important role in the production of electrical energy in a dam.
The water used in a hydroelectric power plant is driven under the pull of gravity.
Energy conversion which leads to the production of electricity is from potential energy more specifically, gravitational potential energy to kinetic energy of the electricity.
Potential energy is the energy due to the position of a body.
Water in a dam, is passed through a channel in dam. The channel is held high up, as the water falls through the channel, it impacts and drives a turbine along its path.
This in turn is connected to a generator that produces electricity.
Gravity increases with the mass of the water and causes the gravitational potential energy of the water to drive the turbines.
