Plz ! on this map, what is the general name for the horizontal lines?

a longitude
b climate zone divisions
c capricorn zones
d latitude
i do not know how to put on the picture thing plz

If you have a map of a fairly large area and it has evenly-spaced horizontal lines crossing it, there's a pretty good chance that the lines are "parallels of latitude".

Each line says that all the points on that one are located at the same angle north (or south) of the equator.

Pick one line and look carefully along it, or right next to one end of it, and there should be a number. That number is the angle between the equator and any point on that line.

Angles are not distances, but on the Earth's surface, you can use them to figure out a distance. If you move STRAIGHT north or south, the distance between two points is about 69.1 miles for EACH degree of difference in their two angles.

the answer is a. at the equator

-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

hope this
