Answer:
B. Geothermal refers to heat sources on the Earth’s crust
Explanation:
- The geothermal energy is the heat that is derived from the storing of energy that creates by the earth's temperature and the earth's crust is origin for this type of energy along with the radioactive decay of the elements of the crust.
- <u>Thus said to be earth's internal heat and needs to be trapped as it can get lost during the formation stages. </u>
- The temperature that occurs at the earth's core and the metal zone reaches up to 4000°C and thus the high temperature causes the rocks to melt and give rise to the temperature in the plastic mantle to get activated by the convection currents that reach the surface.
- Some examples of this geothermal energy are those of the hot spring and the rising lava or the magmas.
seismic waves
Explanation:
waves show stuff like how the respond and flow through the mantle and I also looked it up so if that helps ☺️
Answer:
A city-state, or polis, was the community structure of ancient Greece. Each city-state was organized with an urban center and the surrounding countryside. Characteristics of the city in a polis were outer walls for protection, as well as a public space that included temples and government buildings. The temples and government buildings were often built on the top of a hill, or acropolis. A surviving example of a structure central to an ancient acropolis is the famous Parthenon of Athens. The Parthenon was a temple built to honor the goddess Athena. The majority of a polis’s population lived in the city, as it was the center of trade, commerce, culture, and political activity.
There grew to be over 1,000 city-states in ancient Greece, but the main poleis were Athína (Athens), Spárti (Sparta), Kórinthos (Corinth), Thíva (Thebes), Siracusa (Syracuse), Égina (Aegina), Ródos (Rhodes), Árgos, Erétria, and Elis. Each city-state ruled itself. They differed greatly from the each other in governing philosophies and interests. For example, Sparta was ruled by two kings and a council of elders. It emphasized maintaining a strong military, while Athens valued education and art. In Athens every male citizen had the right to vote, so they were ruled by a democracy. Rather than have a strong army, Athens maintained their navy.
Greek city-states likely developed because of the physical geography of the Mediterranean region. The landscape features rocky, mountainous land and many islands. These physical barriers caused population centers to be relatively isolated from each other. The sea was often the easiest way to move from place to place. Another reason city-states formed, rather than a central, all-encompassing monarchy, was that the Greek aristocracy strove to maintain their city-states’ independence and to unseat any potential tyra
