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.

Answer: Molecular similarities provide evidence for the shared ancestry of life. DNA sequence comparisons can show how different species are related. Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved.

Answer:
Seismic waves are studied by geophysicists called seismologists. Seismic wave fields are recorded by a seismometer, hydrophone (in water), or accelerometer. The propagation velocity of seismic waves depends on density and elasticity of the medium as well as the type of wave.
