Asurfer is actually traveling on which part of a surface wave

Surfer travels at the crest

Explanation:

Waves on the surface of water is known as surface waves in which the disturbance will travel in form of crest and trough.

Now we know that disturbance or energy will travel along the surface due to which the crest and trough will also move along the surface with same speed

Now here surfer travel at the position of the crest of the wave because at that position the surfer will remain at the top of the wave due to which his balancing while he is in motion will be easier.

So here we can say the surfer will remain static with respect to the crest of the wave and crest move with the speed of wave and hence A surfer is actually traveling on CREST of a surface wave

-first use of geothermal energy occurred more than 10,000 years ago in north america by american paleo-indians

-the first industrial use of geothermal energy began near pisa, italy in late 18th century

-in 1904, italian scientist piero ginori conti invented the first geothermal electric power plant in which steam was used to generate the power

-with the above experiment, the first geothermal plant in usa started in 1922 with a capacity of 250 kilowatts

-however, in 1946 first ground-source geothermal heat pump installed at commonwealth building in portland, oregon

-during the 1960’s, pacific gas and electric began operation of first large scale geothermal power plant in san francisco, producing 11 megawatts

-in 1973, when oil crisis began many countries began looking for renewable energy sources and by 1980’s geothermal heat pumps (ghp) started gaining popularity in order to reduce heating and cooling costs

-as effect of climate change started showing results, governments of various countries joined hands to fight against it, for which kyoto protocol was signed in japan in 1997, laid out emission targets for rich countries and required that they transfer funds and technology to developing countries, 184 countries have ratified it
