Geothermal energy is the energy drawn from the earth (geo) by way of the hot rocks that are found there. It is created as a result of the tremendous heating caused by the fission of radioactive elements in the earth's core.
Nobody has even gotten close to directly examining the interior of the Earth. So there is disagreement among geophysicists as to how heated the Earth's core is. However, the speed at which earthquake waves, sometimes known as "seismic waves," move can reveal a lot to scientists about the composition of the Earth.
It is thought that the Earth's core temperature ranges between 5,000 to 7,000 degrees Celsius. That is far colder than the sun's inside, yet roughly as heated as the sun's surface.

True. Historic texts can be trusted to help in the location of archaeological sites.
Archaeological sites
An archaeological site is a location that has been or may be explored using the discipline of archaeology and preserves traces of previous activity. It forms a part of the archaeological record. Sites can include those with few or no apparent remnants above ground as well as ones with standing buildings and other structures.

If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly. ... Scientists are studying exactly how ice caps disappear.
Answer:
All dinosaur fossils found by archeologists have been found a few centimeters below the iridium layer. So, the possibility of finding dinosaur fossils above the iridium layer is very slim.
Explanation:
Over 65 million years ago, dinosaurs roamed the earth but were canceled out as a result of an extraterrestrial impact on the earth's crust. Research proved that an asteroid brought the end of dinosaurs as the element iridium was found in the earth (since iridium is abundant in asteroids and not the earth's crust).
Records of fossils found have been between 13 to 60 centimeters below the iridium or the K-T boundary as it is called.
