Why do volcanoes get hot?
Volcanoes bring up material from deep within the earth. earth's interior is very hot.
Is it true when you study earth's interior geologists often rely on indirect such as evidence from fossils?
No. Fossils tell us about what was living at or near the earths surface in the past, they do not tell us about the Earth's interior. When studying the Earth's interior, geologists look at micro gravity variations (which tell us about density differences in deep rocks), magnetic variations (which tell us a bit about the deep rocks composition) and most importantly seismic records (which tell us about the physical properties of the deep rocks). We also look for deep rocks that have been brought to the surface during the collision of continents (the roots of mountains) and volcanic events (such as diamond pipes).
Why is little known of the interior of the earth?
The extreme heat and pressure inside the Earth make it difficult to penetrate deep enough to directly study it. Most of our knowledge comes from indirect methods like seismic waves and volcanic activity. Additionally, the high cost and technical challenges of drilling deep into the Earth make it difficult to conduct extensive research on its interior.
What is the temperature of the interior of earth 1000k deep?
The temperature at a depth of 1000 km inside the Earth can reach around 1000 to 2000 degrees Celsius. This heat is primarily generated by the radioactive decay of elements in the Earth's mantle and core.
How did deep mines and wells give clues to the nature of the earth and interior?
Deep mines and wells provide valuable insights into the Earth's interior by allowing scientists to access rock samples and fluids from various depths. These samples reveal information about the composition, temperature, and pressure conditions of the Earth's crust and upper mantle. By studying mineral characteristics and seismic activity related to these depths, researchers can infer the geological processes and structures that shape the planet's interior. Additionally, the presence of certain minerals and geothermal gradients can indicate the historical and ongoing tectonic activities.
What is the energy source in vent ecosystems deep in the oceans?
Heat from Earth's interior.
What can be used to map the deep interior of the earth?
The deep interior of the Earth can be mapped using seismic waves. Natural earthquakes produce seismic signals which penetrate the Earth. Timing the arrival of these waves at various sites round the world, gives indication of the shape and the wave velocity in the Earths interior. Rather similar to the way a CAT scan can reveal the interior of a person.
Why do volcanoes get hot?
Volcanoes bring up material from deep within the earth. earth's interior is very hot.
What is endogenic?
endogenic forces have their origin deep down in the earth's interior and they work from below
Who determined that S waves were unable to survive deep passage through the Earth's interior?
I donno. Your mom?
what is the source of all the food in the ecosystems?
The Sun and in the case of deep sea vents, the heat and chemicals from Earth's interior.

How do geologists obtain evidence about earth's interior?
Geologists obtain evidence about the Earth's interior through methods such as studying seismic waves, analyzing rock samples from volcanoes and deep drilling, conducting laboratory experiments on high pressures and temperatures, and studying meteorites which originated in the Earth's interior. These methods help geologists to understand the composition, structure, and processes taking place in the Earth's interior.
What did scientist learn earth's interior by studying rock samples?
They can learn about conditions deep inside Earth, where these rocks formed. In addition, forces inside Earth sometimes blast rock to the surface from depths of more than 100 kilometers. These rocks provide clues about the interior.

What are sources of thermal energy in earth's interior?
The main sources of thermal energy in Earth's interior are residual heat from the planet's formation, radioactive decay of elements like uranium and thorium, and heat generated by the constant churning of molten rock in the Earth's mantle. These sources combine to create the high temperatures found deep within the Earth.

The temperature at a depth of 1000 km inside the Earth can reach around 1000 to 2000 degrees Celsius. This heat is primarily generated by the radioactive decay of elements in the Earth's mantle and core.
